Good to know that you problem solve on things that you have seldom worked and fix things. I really enjoy watching the way you work through things and fix them
I've never been able to fix something by reflowing solder. I was started to think it was just a myth fix. Glad to see it actually works. Hopefully one day I'll be able to find something that actually works on. Also its nice to see that I'm not the only one with a work bench that cluttered, lol!
@@12voltvids I guess i've just been lucky, or unlucky? lol. I do have an old CRT apple monitor I'm gearing up to try repairing maybe I'll find a reflow requiring situation in that one! fingers crossed, lol.
Great job getting it working. Makes me wish I kept my old MDP-455 (same chassis) as I think it was suffering from the exact same issues. It was an average player so I don’t miss it all that much. This 555 definitely has a much nicer look with the wood side panels and metal front facade (mine was painted plastic).
I also have a wonky MDP-455. I've sunk close to 10 hours into trying to fix it and haven't really gotten anywhere. In fact, I made it worse last time by accidentally removing the laser's drive belt. This video is giving me the itch to give it one last ditch effort to get it working, though.
Australia and New Zealand are same as Europe. Nominal 230V for single phase supply and Active is brown/ Neutral is blue (and yellow/green for Earth). Cords are double insulated also. I see there is no additional cable clamps on your plug wires.
Well done :-D, thankfully the laser is still good :-D. I still think the laser pickup is a cause of quite a few dead units. As i don't really like messing with the presets, cleaning and lubing is always my first step.
4:40 Tinning the whole lenght of the wire is prohibited by code (at least here in Europe), because a tinned multistrand copper wire is very soft, the tension of the screw terminal will press it flat over time, and it will cause a loose connection. Tinning just the tip is OK, if the tinned part will not be under the screw (still not OK by the code probably). If it's a spring loaded terminal instead of screw termial, tinning the whole wire would cause less risk, but in those cases using a ferrule is the way. With this type of screw terminal, hooking the bare stranded wire around the screw gives the most reliable connection in the long term. Special circular ferrules are available for this purpose, but I have never seen a crimp tool for them or the circular ferrules themselves sold anywhere. I only saw them applied to wires in some factory made equipment.
I don't advise tinning the tip either. The nature of solder will more likely than not mean the whole length is partially soldered. It is almost unavoidable.
@@martinda7446 Yes, I know it's very hard to solder just the tip, capillary effect can easily suck up the solder between the strands much farther than you would want, even way under the insulation if you keep it melted for long enough. Soldering with high temp very quickly might do it, but it's fiddly and not very repeatable.
You are an excellent experienced engineer. I am sure that you can hear and see that laser pick up is not focusing, it is trying to focus. Nonetheless, it is unable to do it.
Amazing how much better the video quality got toward the end looks great. I got one of those cd videos from bon Jovi never got to see the video just thought it was a cool cd back then and bought it.
@@tedbell4416 no actually it just started working on its own. What do you think? I didn't tell you exactly what the problem was. Yes the connections on the adjustment pots a few of them were cracked for sure and the adjustment trimmers himself needed some cleaner on them. But the two I sees that I resoldered on the board one of them the little flat pack ic several pins were cracked solder. It did need dialing in too but once I got it dialed in it played perfectly and it's playing perfect now spins up immediately starts playing the desk no hesitation. that's one of the reasons why I'm more reluctant to fix that old pioneer 10:30 with the broken gear on the loading Trey it's because when I can pick up a really good machine cheap and get it going then why would I spend money to have a gear 3D printed for an old basic machine
What magic is this?????? No dead pickup? Dry joints and that's it? Holy crap. I worked on so many of them and I can't believe your luck. So many bad pickups at huge prices. Well played. I really thought it would be a no-fix
gud day sir! is it ok for you if i ask you,? where can i purchase a chip price of laser optical block KHS 130A,,KHS 150A. and also for pioneer lens.hope for your reply.
Was it the solder or the spray down/adjustment that truly resolved the issue? Could not really see the fault in the solder points in the video. What are the signs of bad solder points on a board? GREAT job as usual, btw.
When I have to resort to using a "parts unit" to repair something, I save the whole original AC cable (along with lots of other parts, of course.) I have a Sony tape deck that I imported from Europe on the way that will receive the cord salvaged from a Sony CD player with a dead laser. It just feels more authentic to use OEM parts without having to hack new plugs onto the end of the original cable. :-) (Don't get me wrong, of course, anything that works is a legit fix, but it's the little things, y'know?)
I agree on the challenge aspect of broken units, too. I would usually prefer to buy one that is not working, but fixable, than one that works. I will attempt to fix it. Someone else might just throw it away. Let _that_ guy take the one that "just works." I fully re-cap just about everything I get, or _at least_ the power supply and servo sections, just as much a matter of course as wiping down the top and front panels. A lot of times, after recapping, cleaning, re-lubing, and exercising the mechanisms a few times, they just spring to life -- whether they were previously working or not!
It's usually not hard and very cheap to find replacement lasers for Sony CD players, if it's not very old. KSS-213A-B-C-D-E-F are the most common and dirt cheap on ebay and Aliexpress, sometimes you can find NOS originals, but the third party ones are usually not that bad either (even if they fail within 2 years, it's so cheap it's worth replacing it again). I don't like the plastic suspension of the lens, though.
I have 5 of those video CDs also. Like you said very very rare. Three play, two kinda of play with lots of audio distortion. Warping again, not quite flat. Hay, what is the RPM on the video part of the small disc. Must be at least five times normal. These really spin up.
Around 5000 rpm slowing to 3000. I have 3 CD video. Robert cray smoking gun, David Bowie ashes to ashes and the flight of the dream team. Very very rare indeed.
The first disc you were playing was badly warped. I have an 8 inch that does the same thing. I place that disc under several LPS, for about a month and it plays fine. Once I store it away upright like an LP and the warp comes back. If you want to sell some LD's let me know. I might take on the warped copies just for the fun of it.
Dave what is your personal view on tinning the entire wire, our teachers in school told us not to do that. As they said it will make the wires come lose easier, I always tinned my wires completely and I never experienced any problems?
You're right, it's not up to code. Tinned multistrand wires are very soft, the tension of the screw terminal will flatten it out over time, causing loose connection. A lot of manufacturers in the '80s here in Eastern-Europe did this and those connections are completely loose now. It only takes a few months, but after some years it will be *very* loose.
My guess is because the stranded wire is much more flexible than if it would be if it was soldered. It could allow the weak individual flexible strands to break right below the soldered bit of the wire, with prolonged occasional movement of the cable. But it shouldn't be an issue if the cable has a strain relief of some kind. As with a mains plug.
I'm curious about the optical pick-up, is it a standard audio CD pickup or specific for LaserDiscs ? laser wavelength is the same but RF output in a LD has surely higher bandwidth. It is rare to find these days people selling broken stuff for what it is actually worth (nothing): I see people asking 30/40 EUR for non-working hi-fi equipment boasting the fact they are basically giving it away for free !
The wavelength is the same as for CD but the optical pickup is totally different. First of all it's much larger than a CD pickup, and the traverse that is mounted on also has tilt ability. So it works off of an x and y axis for up and down and side to side tracking as well as a tilt axis to align the laser up precisely with the optical pits on a laser disc which may not be perpendicular just due to the size of the disc. So if you watch the sled servo assembly you will see that it actually tilts slightly as the movie plays. Physically it's much larger than a CD laser.
What you called "zip wire" certainly exists in Europe. It's not as common anymore, maybe it's no longer allowed, but you definitely see it on older devices.
Remembering European appliance cable colours... BLue Left , BRown Right and Green (Earth) up the middle , on UK plugs that require a green and yellow earth fitted.
But from which view? Wire or pins towards you? For most non-UK European plugs (round Shuko with grounding on the periphery, or this flat low power one), polarity doesn't matter as they're symmetrical and fits into the socket both ways around.
The European plug in the SONY LD player is actually non-polarised. It is used when the mains go straight into a transformer that will completely isolate the power supply output voltages.The metal chassis will set the ground level reference.
i have an RCA Laser disk or what ever It is that Plays the Ones that Come in the Sleeve one has to insert into player then Remove to allow the disc to remain in player, this one has a stylus similar to a record player, now it only plays half the disc then stops and restarts from the begginning, like Mech needs some work as the stylus will not travel the full rail without help, so gonna try relubing the rails and see what happens, it was given to me a few years ago.
That's a CED, capacitive electronic disc. Uses a stylus to track a spiral groove in the disc but unlike a phonograph record where the stylus wiggles back and forth to reproduce the signal, in a CED the depth of the groove varies slightly, the stylus does not actually ride up and down in the groove it rides along the edges of the groove but the distance between the bottom of the groove and the stylus changes which affects the capacitance of the disc at the point where the stylus is running and this difference in capacitance is measured to produce a signal. Was quite an ingenious idea but it also almost bankrupted the company. Did you know that RCA started working on that in 1963. They brought it to market in the early eighties but it already been surpassed by laser optical readout so it died a quick death. Today they are considered collectors items because RCA did what was unthinkable back then they bought all the players back and all the inventory of movies back from the retailers and put them in a giant crusher. Kind of like what general motors did for the ev1. So any of those players that are out there now were collected by people that did not return them because once the program was scrapped and no new movies were being released RCA had a buyback program where a customer could send the player back and the movies back to RCA and they would get a discount on a new VHS purchase. Many people did take them up on that offer, and I know this because the dealer I was working for at the time was an RCA dealer as well as Sony and Panasonic and a few of the players that we sold came back and were traded in on something else. The dealer then returned them back to RCA for a full credit just like they would have if the unit had never been sold and it was a brand new unit. The CED player cost RCA more money and was likely one of the things that caused RCA to not only lose its market share but ultimately end up being acquired by Thompson.
Technology connection did a video series on the CED, it is indeed a textbook example on how to do the wrong decision in every step of the development and marketing of a product.
@@12voltvids Never knew that, And i have A few Of the disc and the one player yet, But as i say it needs work on it, it does play , but only half the Movie then starts over unless its Helped with tracking, Like its Jamming some wheres, not sure, But i used it a few times as is, but Might try getting it Fixed if Worth the Trouble, as i have alot of good Movies on them CED disc.I had this Machine a few Years now.
Nice score for 10 dollars. People in the arcade machine collecting hobby with specific laser disc cabinets, like dragons lair and less than handful more laser disc games. Covet these laser disc players. As functioning units become far and few between these days. Might be a little profit to be made there, if you ever decide to sell it on.
Hey Sir, I believe I have heard that you do camera repairs. I have a 2002 Sony Handycam TRV-340 that(like all old camcorders) can't playback tapes. Do you do camera repairs? If so, what process can we pursue to get my camcorder repaired?
Hello sir, I hope you can advise me. I have a sony MDP-999 LD/CD player. I got a new laser installed myself. LD plays perfectly. However, It cannot play CD. When I put CD in it know it CD insterted. The head moved to the CD. It make very loud moter noise from the laser. Could you help how to made adjustment for CD? I can see all the adjustment switch at the side. CD track focus gain, CD track bias, CD track gain, CD T.J (I do not know what it is) RF. Please help .
@@alanwong3980 if it's spindle height there is a lock screw on the disk Chuck that you losen to adjust. I have just tried adjusting up or down a bit untill it reads. The manual i am sure has the procedure but i don't have it and don't work on enough to bother getting one.
@@alanwong3980 not familiar with that model. Never worked on one. I actually did very lite work on any laserdisk because they were never that popular. Have see. Perhaps 10 in 40 years.
Everyone knows that multi system equipment were a compromise. They did everything but not that well. Those who were serious in Europe boughy an ntsc player and monitor so they could watch ntsc disks in the best we quality available at the time.
Might show up as some dots of noise on the picture. It's quite hard to make a laserdisc unplayable or skipping. Even ones with severe laser rot are usually playable, just having very bad picture quality.
They usually cause no trouble because the laser is focused deep inside the disk. If the obstruction was really bad you might see it but generally it's not noticeable because remember the video signal is analog but it's FM modulated. so what comes off the desk with his red from the laser is a series of FM carriers which convey the information.
Why does a NTSC player have a EU plug on it and why does it operate on both 120 and 240 volts? I think few Europeans would have wanted a pure Ntsc player, Most Europeans had multi standard ones that could do both PAL and Ntsc, most discs here in Sweden at least where imported from America or the UK so having a multi standard one made the most sense. I got like 50/50 with PAL and Ntsc discs got a few discs from Japan and 2 Swedish ones but the other ones are all Brittish and American
From what I have gathered, Sony seems to have used two different models of NTSC players. One, I think, was just NA -- US and Canada, specifically. The other was for Europe and Asia. I have a Sony MDP-600 and a Sony MDP-A1. It's the same player, except there's a PCB attached to the transformer that, on the MDP-600, just has some filtering and a cable harness that goes to the PSU board. That's the NA variant. On the A1, it adds a voltage selector (the same circular kind shown in this video.) There are so many weird regional power and line frequency mix-and-match combinations in Europe and Asia. 100 or 200 volts. 50 or 60 Hz. NTSC or PAL, or NTSC but with PAL color, etc. Who knows where this player was originally sold, but it doesn't surprise me at all to see NTSC with a European plug on it. Somewhere, that's normal.
@@nickwallette6201 Well did some research only Peru, Burma and Guyana seem to be 220 volts and Ntsc and they don't seem to use a EU plug either so dk why it has that plug on it, Even if the player was from like Peru I think it would have had a diffrent plug on it
It's weird to think but because of all the DRM crap on blu-ray discs we might lose the ability to play them before even DVDs. Intel just removed an instruction set from its newer processors that was required to play Ultra-HD Blu-rays on PC. I can already see myself trying to repair an old blu-ray player in 30 years just to keep my discs playing...
Yeah. The whole key-management fiasco is something up with which consumers should not agree to put. Every DVD and BD disc I acquire goes straight into a computer running AnyDVD HD, and into an MKV file on my NAS. I think I have yet to actually spin a single Blu-ray disc in a player -- even a software player. I never even bought a standalone DVD player or BD player, until a couple weeks ago when I bought an old SACD player that _happens_ to play DVDs.
Yes, blue is neutral, brown is phase / L1. But it doesn't matter anyway, because in Europe all plugs have no direction, so if connected, both cables have a 50% chance to be phase. This is true for Euro-plugs like that, but also for plugs with a third earth-wire (yellow-green). So everything with a cable must be isolated or grounded, because you can't tell which cable is phase and which is neutral. Metal cases must be grounded, non-conducting cases (like most HiFi equipment) can be just isolated. Standard colors in many European countries are nowadays black, brown, grey for phases (L1, L2, L3, where between phases are 360V), blue is neutral and green-yellow is earth, but that varies from country to country - let alone older installations... Common are 230V and most homes have three phases (120°), so powerful machines can have 360V three-phase-current.
It's not actually a problem because these things spin so fast that you get this centrifugal force on the disc that flattens it out. when you look at the wobble as it's starting to spin up you would think how the hell can this thing play but it does. It's the centrifugal force in gyroscopic effect straightens the Disc out and the laser tracks at fine. Over the last couple weeks I've played probably 30 discs in this player and they've all played perfect. The best $10 investment I think I ever made I'm trying to buy another one right now but the guy won't take my offer for a broken player.
If you are patient, you might find one for free. I accidentally came upon a Mitsubishi, M-V7057 (clone of a Pioneer, CLD-D704) that the seller just wanted a home for. I guess after we talked, he was more than happy to know I was the kind of person he thought it should go to.
Im bipolar. Thankfuly its well managed on meds. Your joke is both slightly offensive but mostly funny in that “oh. That’s just wrong. *chuckle* “ kind of way
I don't even remember it because the camera was off. It would have been either bipolar capacitor or a bipolar junction transistor joke. I worked for someone that was BPD. There were days he was ok and then there were days where everyone else around him was looking for a bus to step in front of. Yes it was that bad. The best day of my life was walking away from that place. It was better than my wedding day and it was better than watching my 2 kids being born. That gives you an idea on how miserable this one person made everyone else when he was in one of his moods.
380V between phases is for 220V phase2ground. The nominal/harmonised 230V phase2ground makes 400V between phases, and 240V phase2ground makes 415V between phases. (With 120° between phases, the trig works out to a factor of √3)
It's like owning an antique car. Why have an old car? New cars get better mileage, have A/C, etc. Having a classic media player is enjoying part of man's history! Hail LD! Hail Betamax!
I bought this model back in 1993 when I was still a teenager, time flies.

"The Hunter" , very funny movie ! Love it.
Levar Burton was in “The Hunter” with Steve McQueen.
Remembering European appliance cable colours... BLue Left , BRown Right and Green (Earth) up the middle , on UK plugs that require a green and yellow earth fitted.
But from which view? Wire or pins towards you?
For most non-UK European plugs (round Shuko with grounding on the periphery, or this flat low power one), polarity doesn't matter as they're symmetrical and fits into the socket both ways around.
The European plug in the SONY LD player is actually non-polarised. It is used when the mains go straight into a transformer that will completely isolate the power supply output voltages.The metal chassis will set the ground level reference.
i have an RCA Laser disk or what ever It is that Plays the Ones that Come in the Sleeve one has to insert into player then Remove to allow the disc to remain in player, this one has a stylus similar to a record player, now it only plays half the disc then stops and restarts from the begginning, like Mech needs some work as the stylus will not travel the full rail without help, so gonna try relubing the rails and see what happens, it was given to me a few years ago.
That's a CED, capacitive electronic disc. Uses a stylus to track a spiral groove in the disc but unlike a phonograph record where the stylus wiggles back and forth to reproduce the signal, in a CED the depth of the groove varies slightly, the stylus does not actually ride up and down in the groove it rides along the edges of the groove but the distance between the bottom of the groove and the stylus changes which affects the capacitance of the disc at the point where the stylus is running and this difference in capacitance is measured to produce a signal. Was quite an ingenious idea but it also almost bankrupted the company. Did you know that RCA started working on that in 1963. They brought it to market in the early eighties but it already been surpassed by laser optical readout so it died a quick death. Today they are considered collectors items because RCA did what was unthinkable back then they bought all the players back and all the inventory of movies back from the retailers and put them in a giant crusher. Kind of like what general motors did for the ev1. So any of those players that are out there now were collected by people that did not return them because once the program was scrapped and no new movies were being released RCA had a buyback program where a customer could send the player back and the movies back to RCA and they would get a discount on a new VHS purchase. Many people did take them up on that offer, and I know this because the dealer I was working for at the time was an RCA dealer as well as Sony and Panasonic and a few of the players that we sold came back and were traded in on something else. The dealer then returned them back to RCA for a full credit just like they would have if the unit had never been sold and it was a brand new unit. The CED player cost RCA more money and was likely one of the things that caused RCA to not only lose its market share but ultimately end up being acquired by Thompson.
Technology connection did a video series on the CED, it is indeed a textbook example on how to do the wrong decision in every step of the development and marketing of a product.
@@12voltvids Never knew that, And i have A few Of the disc and the one player yet, But as i say it needs work on it, it does play , but only half the Movie then starts over unless its Helped with tracking, Like its Jamming some wheres, not sure, But i used it a few times as is, but Might try getting it Fixed if Worth the Trouble, as i have alot of good Movies on them CED disc.I had this Machine a few Years now.
I want a collection video
Nice score for 10 dollars. People in the arcade machine collecting hobby with specific laser disc cabinets, like dragons lair and less than handful more laser disc games. Covet these laser disc players. As functioning units become far and few between these days. Might be a little profit to be made there, if you ever decide to sell it on.
Believe it or not any type of optical disk player will play fine with a fair bit of wobble.
Were can I get that solder iron at I want one
I did a review of it.
Hey Sir, I believe I have heard that you do camera repairs. I have a 2002 Sony Handycam TRV-340 that(like all old camcorders) can't playback tapes. Do you do camera repairs? If so, what process can we pursue to get my camcorder repaired?
plugs in UK are a lot different
Hello sir, I hope you can advise me. I have a sony MDP-999 LD/CD player. I got a new laser installed myself. LD plays perfectly. However, It cannot play CD. When I put CD in it know it CD insterted. The head moved to the CD. It make very loud moter noise from the laser. Could you help how to made adjustment for CD? I can see all the adjustment switch at the side. CD track focus gain, CD track bias, CD track gain, CD T.J (I do not know what it is) RF. Please help .
Did you check spindle height?
@@12voltvids Could you advise how to do it?
Do you mean the spinning motor? Mdp 999 use two set of motor. One for ld and one for cd.
@@alanwong3980 if it's spindle height there is a lock screw on the disk Chuck that you losen to adjust. I have just tried adjusting up or down a bit untill it reads. The manual i am sure has the procedure but i don't have it and don't work on enough to bother getting one.
@@alanwong3980 not familiar with that model. Never worked on one. I actually did very lite work on any laserdisk because they were never that popular. Have see. Perhaps 10 in 40 years.
Im sure is because is form Europe is pal and the dish format is ntsc not pal version
Everyone knows that multi system equipment were a compromise. They did everything but not that well. Those who were serious in Europe boughy an ntsc player and monitor so they could watch ntsc disks in the best we quality available at the time.
@@12voltvids ha ok cool
Awesome video👍
This machine must have been a fairly high in their range at the time. It's the only one i've ever seen with the fake wood side cheeks on it.
They've not fake. Real wood just like the es line.
Could it play SACD ?
This was long before SACD.
I was lucky with a LG DVD bluray player...
yes I fixed a Samsung blu ray it had a spring in the tray
@@EastAngliaUK plastic parts
How much does fingerprints affect laser disks? I see you touch them all the time.
Might show up as some dots of noise on the picture. It's quite hard to make a laserdisc unplayable or skipping. Even ones with severe laser rot are usually playable, just having very bad picture quality.
They usually cause no trouble because the laser is focused deep inside the disk. If the obstruction was really bad you might see it but generally it's not noticeable because remember the video signal is analog but it's FM modulated. so what comes off the desk with his red from the laser is a series of FM carriers which convey the information.
Now this is one thing i have never seen in real life before
I find that using a hot air rework station set to 300C will fix these old stretched and deformed belts.
Why does a NTSC player have a EU plug on it and why does it operate on both 120 and 240 volts? I think few Europeans would have wanted a pure Ntsc player, Most Europeans had multi standard ones that could do both PAL and Ntsc, most discs here in Sweden at least where imported from America or the UK so having a multi standard one made the most sense. I got like 50/50 with PAL and Ntsc discs got a few discs from Japan and 2 Swedish ones but the other ones are all Brittish and American
From what I have gathered, Sony seems to have used two different models of NTSC players. One, I think, was just NA -- US and Canada, specifically. The other was for Europe and Asia.
I have a Sony MDP-600 and a Sony MDP-A1. It's the same player, except there's a PCB attached to the transformer that, on the MDP-600, just has some filtering and a cable harness that goes to the PSU board. That's the NA variant. On the A1, it adds a voltage selector (the same circular kind shown in this video.)
There are so many weird regional power and line frequency mix-and-match combinations in Europe and Asia. 100 or 200 volts. 50 or 60 Hz. NTSC or PAL, or NTSC but with PAL color, etc. Who knows where this player was originally sold, but it doesn't surprise me at all to see NTSC with a European plug on it. Somewhere, that's normal.
@@nickwallette6201 Well did some research only Peru, Burma and Guyana seem to be 220 volts and Ntsc and they don't seem to use a EU plug either so dk why it has that plug on it, Even if the player was from like Peru I think it would have had a diffrent plug on it
It's weird to think but because of all the DRM crap on blu-ray discs we might lose the ability to play them before even DVDs. Intel just removed an instruction set from its newer processors that was required to play Ultra-HD Blu-rays on PC. I can already see myself trying to repair an old blu-ray player in 30 years just to keep my discs playing...
Yeah. The whole key-management fiasco is something up with which consumers should not agree to put. Every DVD and BD disc I acquire goes straight into a computer running AnyDVD HD, and into an MKV file on my NAS. I think I have yet to actually spin a single Blu-ray disc in a player -- even a software player.
I never even bought a standalone DVD player or BD player, until a couple weeks ago when I bought an old SACD player that _happens_ to play DVDs.
Yes, blue is neutral, brown is phase / L1. But it doesn't matter anyway, because in Europe all plugs have no direction, so if connected, both cables have a 50% chance to be phase. This is true for Euro-plugs like that, but also for plugs with a third earth-wire (yellow-green). So everything with a cable must be isolated or grounded, because you can't tell which cable is phase and which is neutral. Metal cases must be grounded, non-conducting cases (like most HiFi equipment) can be just isolated.
Standard colors in many European countries are nowadays black, brown, grey for phases (L1, L2, L3, where between phases are 360V), blue is neutral and green-yellow is earth, but that varies from country to country - let alone older installations...
Common are 230V and most homes have three phases (120°), so powerful machines can have 360V three-phase-current.
Oh yeah, LOVE me some Robert Cray/Smoking Gun!!!!!
Now donate it to the shredder channel. Cool Vid!
Not this one. Too good a player
I look to get a remote PIONEER VSX-403
1995
The warping in that disc look pretty bad. I know nothing about them but it looks pretty bad
It's not actually a problem because these things spin so fast that you get this centrifugal force on the disc that flattens it out. when you look at the wobble as it's starting to spin up you would think how the hell can this thing play but it does. It's the centrifugal force in gyroscopic effect straightens the Disc out and the laser tracks at fine. Over the last couple weeks I've played probably 30 discs in this player and they've all played perfect. The best $10 investment I think I ever made I'm trying to buy another one right now but the guy won't take my offer for a broken player.
I wish I could find one for $10
If you are patient, you might find one for free. I accidentally came upon a Mitsubishi, M-V7057 (clone of a Pioneer, CLD-D704) that the seller just wanted a home for. I guess after we talked, he was more than happy to know I was the kind of person he thought it should go to.
I bought another one for 10 bucks
Im bipolar. Thankfuly its well managed on meds. Your joke is both slightly offensive but mostly funny in that “oh. That’s just wrong. *chuckle* “ kind of way
I don't even remember it because the camera was off. It would have been either bipolar capacitor or a bipolar junction transistor joke. I worked for someone that was BPD. There were days he was ok and then there were days where everyone else around him was looking for a bus to step in front of. Yes it was that bad. The best day of my life was walking away from that place. It was better than my wedding day and it was better than watching my 2 kids being born. That gives you an idea on how miserable this one person made everyone else when he was in one of his moods.
Laserdisc size in 16,7 gigabyte
It's an analog format. The digital audio soundtrack was under 600 meg per side as only 60 min max of 16 bit 44.1khz digital audio.
Try cleaning lens
Watch and learn
maybe something fun to know in europe 3 phase will be 380 volts and single phase as dave said 240 volts
380V between phases is for 220V phase2ground. The nominal/harmonised 230V phase2ground makes 400V between phases, and 240V phase2ground makes 415V between phases.
(With 120° between phases, the trig works out to a factor of √3)
that is a dutch plug 😀
good it was a lose connection
Bad lead free solder
Not tied to this video just thought you may enjoy this physics talk: ruclips.net/video/P1ww1IXRfTA/видео.html
Bargain for $10 👍😀
I think I overpaid
If you ever decide to sell it, I’d buy it…if the price was reasonable.
Why you need Laser Disk now?
Trash Museum!
It's like owning an antique car. Why have an old car? New cars get better mileage, have A/C, etc. Having a classic media player is enjoying part of man's history! Hail LD! Hail Betamax!
I have many movies that are just not available on any other format. Many old classics.
