I really enjoy the VCR repair Videos, I can't get enough of them, also I always learn something new when I watch your videos, I remember when I worked at a repair shop that we had this dummy video cassette that we could use in a VCR to put it into the fully loaded mode so that we could fasten the front mounted screws in the cassette basket
Hi there! I just wanted to say thanks man , for what? All your VCR repair videos as they have helped me learn alot. From watching these videos and seeing certain things that are similar in all models (Mode-encoder switch for one) i was able to fix up my old Samsung World Wide VCR that had me convinced the unit was destined for the trash ( Was randomly rewinding, ejecting and then stalling and when it would play the picture was full of artefacting) But, upon carefully removing the loader and head drum, checking the mode-encoder switch and finding it very oxidised i gave it a thorough clean. And, thanks to your videos too i saw how to adjust the tape alignment. Through doing all that the VCR works a treat now and im very glad because i nearly dropped a few hundred on a Panasonic NV-W1/W3 unit because i needed a multi-region VCR for transfers i do. So thanks very much for all your videos, they certainly helped me out!
Great video as always👍👍 love these old vcr's & old electronics videos it brings back memories of the 80's😇 as i used to help out (as a kid) in a repair shop and got to see many vcr's, stereos (remember when audio systems were stack up and those speakers) tv's and 80's electronics in general That is why i enjoy these videos & channel Thanks👍👍again for your time and for uploading these videos
As a school system audio visual repair tech from 1980 to 2010, I repaired a lot of these. Service information was hard to come by until the internet. Ahh, the "good old days".
Thanks you about excelent classes. I like it. With you I have learn very much and the electronic does not cause me afraid or dude. Thanks you very much. Bless yo you.
Thanks for a great channel, love your video's. I have a VCR thar won't power up. It makes a clicking noise in power supply. Do you have any suggestions? Thanks :-)
Nice one with the double bearing tower capstan. Haven't seen something like that since the Panasonic K mechanism and some '90s Sony. I certainly haven't seen this in a VCR this late: it was made in 2002. You can see it on the loading motor at 8:04 (0212 date code). I wonder who made this, maybe Funai? But I haven't seen this type of capstan in any Funai/Orion VCRs either. JVC maybe?
Well I have a Hitachi 8mm Rapid Reflex. It plays but I have some horizontal lines maybe with some black and white coming in . I'm not sure what the issue is be it almost plays if you know what I mean.
I actually like this cam mechanism. Plastic fantastic, but at least it doesn't need to move long arms and linkages with too much leverage and friction. It also isn't driven by a belt drive, that's prone to slip on the motor pulley once the cam mechanism gets jammed. That was a frequent failure mode of central cam gear type servo systems (I'm looking at you, Funai). The forced setup screen is just outrageous. Almost looks to me like a partial sabotage attempt from a worker who did the programming of it. Just as one possibility. BigClive did once a taste test of denaturated alc. His reaction was priceless.
Is it the mode switch if a VCR loads a tape, then shuts down, while the guides do not retract, ( or the reels do not take up the slack) so you cannot take the tape out? The only way to get the tape free is take the top off and lift it off of the guides? It's a VCR DVD recorder combo.
Do they grease all the gears?I never seen 99 percent before all could find is 50 percent ,I use for cleaning tube radio chais ,When this virus stuff is done I will try to find good alcohol, you are right it's hard to find very hard
that looks very like the sharp I fixed for the brother in law! It had the same fault, the gear on the side had gone out of place with everything else. As it was his and I didn't much like his constant wanting everything for nothing, I just made sure it was in the open position and prised the long plastic but out until it was fully unloaded. Strange thing is he never came back with it, it worked fine after that. I didn't much care for VCRs anyway, pain in the butt. But I was surprised he didn't reappear with it, maybe he thought I was a bit rough with it or it ran fine after that, I don't know I never asked. It was his VCR and no one was allowed to use it, selfish to the last!
I would like to know why you don't usually remove the head auto clean assembly. In time it could cause much pain, at least it did to my vcr. The heads almost got hit by the plastic arm. BTW awesome repair video.
The plastic arm should not be able to hit the heads, even if the foam/felt/silicone rubber cleaning wheel is missing. Only the foam based head cleaners are really problematic. The ones that made of felt discs or silicone rubber, I used to clean them with IPA, and if they are worn, just flip them around.
They were pure marketing gimmickry. I always remove those as a matter of course and I don't know any technicians that leave them in there. The foam are indeed the worst, they can put sticky mess all over the drum. The other types just redeposit crap on the drum and can harden and wreck the heads. It is like using the same Q tip to clean your ears with every single day!
(20:10) - There is no ethanol or methanol in isopropyl alcohol. It is a chemical in it's own right. Ethyl alcohol (Ethanol) with the addition of methyl alcohol (methanol) is is generally called *_methylated spirits_* or *_"denatured alcohol"_* and is usually dyed purple to indicate that it's toxic. Isopropyl alcohol, commonly called isopropanol is a colorless, flammable chemical compound (chemical formula CH3CHOHCH3) with a strong odor. As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of 1-propanol and ethyl methyl ether. >

99% is denatured. Best to use 99% it evaporates without leaving anything behind. The 70% stuff the alcohol evaporates and leaves water behind which evaporates slower.
I have a DVD/VCR combo unit my mom got me for Christmas in 2003. Haven't used it in a few years and I have tapes I really need to transfer over to discs. Chalk it up to being lazy I guess.
I believe I said that. You need to dilute it as using it pure will not disinfect properly. It is the water that makes it work. I said 70% was not as good as a cleaner because of the water content.
For a cheap-ee it seemed quite decent for playback :-D. I'm no lover of deck on pcb designs, also having the switchmode psu on the same board is a no no for me. Dam remote only units, utterly stupid design.
You've just re claimed the tiltle of "The King of VCRs", The person who stole it from you finally snapped when he heard your cat meowing in awe
Not only can he fix anything, he can read my mind and knows when I need a Sanyo VCR repair video.
No matter how many of your repair videos I see, I always see something new an I end up learning something. 👍🏼👍🏼
That guy should keep getting angry if it means you upload so much, I'm thoroughly enjoying it! And it's VCR stuff too, best week ever so far!
I'm so excited. I think in few years, no one will have the know how to fix such devices. Your knowledge is enormous. Thx.

VCR’s had amazing engineering. I’m surprised that they even worked consistently. I still have my JVC and it works great.

More power to you. I do not miss working on those things. To this day I occasionally wake up in a panic screaming "MODE SWITCH!" and cussing out Sony.
Great work Dave really appreciate the high level of detail re Timing
Very interresting explaination about those Sensors and mechanism

Likely yes
My Panasonic VCR is having power supply issue, is there any way capacitors can damage. Show no sign of burst or swelling.

You replace them. The led gets weak.

What's the name of that contact cleaner??? Can I use petrol instead ??
I used deoxit this time but nutrol is another one. Nutrol is petroleum based. Has diesel in it.

Counter counts control track. If head dirty counter won't move.
@@12voltvids thanks sir ,I will clean both audio and video head
Those are about forty five dollars at Walmart ten years ago.
Same frustration here, can't find 99% IPA at the store.

maybe a ir remote app for your phone will work. i use it al the time.
Looks like the looser with two YT accounts has been here already and disliked this video.
Well at least he/she has something to do...
I've not even watched the video yet. But sounds like the mode switch needs cleaning.
Mechanical alignment.
(21:03) - That 99% isopropanol is perfect for making hand sanitizer.
You simply dilute it to the desired strength with distilled water.

Is 91% Isopropyl Alcohol good enough? That's all the stores seem to carry around here. Haven't seen 99% in years.
That is still 9% water. I wouldn't use it myself. Try Costco. That is where this newest bottle that was given to me came from.
Please do a give away of one of your vcr ...it will be highly appreciated sir
are you gonna tidy up your lab?
Why would I do that?
