    These older vcr's were complex as said, and repairing them is a labour of love.
    Any gear from that era combined complex mechanics with numerous pcb's
    that ran hot, so dried out capacitors were common.
    The mechanics require regular tlc, left to dry out sooner or later something jams
    taking the motor with it.
    A classic example of older gear not being better, the same goes for tape recorders
    cassette recorders, and my pet nightmare early laserdisc players.
    Thankfully the early Philips laservision players were too expensive to sell,
    trying to realign one will realy learn you to swear!

    Nissan actually used similar optical encoders inside the distributor of several v6 engines of the late 90s to track the position of the cam shaft, everything was made of metal and they hardly ever failed.

    The large spring-loaded gear on the right-hand side of the front loader is common to breaking. It happened recently on my HR-D120MS. Luckily I had a replacement from a scrap machine of the same type.

    My parents had a Finnish ASA branded VHS VCR since the 80's, I think it survived at least to 2006, and most of the time it worked ok, but image quality wasn't very good, it was grainy.
    Eventually it started eating and damaging tapes, it was serviced at least once, but it didn't last long even after the service.
    My 2003 Philips VHS VCR is much better, it's smaller, it has on-screen menu, much better image quality and up until recent years, it's been working reliably, and most of the time still does. It just sometimes has a "bad day", malfunctions and flashes fault code "2", but so far it has recovered immediatly simply re-starting it.
    It has not damaged any tapes yet, which also makes it better, so from my experience, I agree, old VCR's aren't always better.
    I accidentally recently inserted damaged tape in it and the tape refused to play, I think it jammed the play mechanism, but luckily ejected normally and no damage happened to the VCR, it still plays normally with good tapes even after that bad tape. It was old tape destroyed by that darn old ASA VCR and I hadn't marked it as faulty, doh! Now I did and maybe I should throw it away, but on the other hand, might be good to have it for possible spare parts?

Professional DV is identical to the consumer format except that it spotted locked audio, meaning the audio clock was locked to the video clock. Consumer DV the audio clock is free running. That was designed in to the format (digital 8 is the same) to discourage their use for anything professional.

      All the old ones were very prone to break down. how do you think so many of us made a living fixing VCRs? Reliability on all of them from the 1980s into the mid-90s was abyssimal. It wasn't just the Hitachi ones with the belts that failed all the time same was at RCA used they all had horrendous problems alignment guides coming loose back tension brakes failing eating tapes. Then there were the composite ICS that were used you know the ones that were encapsulated epoxy we're feeling left right and center. It was the heyday of for a VCR repair and everyone that was in the game made a ton of money fixing them VCR repair is what kept many businesses in business. or what's the reliability got better which they did they got a lot better in the 90s you know when the right plastic mechanisms came out sure there were horror stories of gears and stuff breaking usually when kids shove things into them that weren't supposed to go into VCRs but reliability wise the later generations with their light plastic mechanism and very few moving parts or much better in terms of reliability

      @12voltvids  Год назад +1

      They work on the same concept helical scan. Was actually developed for a video recorders first and then digital audio tape use the same design with a rotating head to scan tracks at a diagonal angle onto the tape. The difference being video requires 180° wrap so that there is always one head in contact with the tape at all times as it's an analog system and digital audio tape only uses a 90° wrap. This is because with digital audio there's memory so the information can be stored in memory until the head is in position and then it writes that frame of data onto the tape while it's storing data for the next frame. Digital audio tape having half the contact area of a VCR results in much lower head wear and much lower tapewear.

      @12voltvids  Год назад +1

      Every time I get someone tell me they want to fix their 40-year-old VCR because they were built so much better and so much heavier than the new ones. the reason they were so much heavier was because they had a lot of little metal parts Little mechanical parts leavers and cams and all kinds of other metal parts that were being controlled by guess what? Plastic gears. Guess what happens to metal parts when they sit around for a while? Lubricants dry up turn to glue, then guess what happens to plastic parts that drive those metal parts when they try to operate for the first time in 25 years when the metal movable parts have glued themselves together? It's not going to be the metal it breaks it's going to be the plastic out unobtainium parts. I laughed at so many people disagree when I state that the last generation of VCRs that was made even though most of them were made by funai were the best VCRs made. The reason being is that even though they're all pretty much plastic plastic parts don't rust plastic parts don't seize up yes they can break if you abuse them are stack them on sale on top of a hot amplifier you can run some into some problems however if looked after the plastic is very durable and will last a long time. It doesn't need lubrication the same way that metal parts do and plastic doesn't rust. Many people view these late model VCRs as being cheap because a) they were cheap and b) they are lite. Remember this phrase the reliability of any electronic device is inversely proportional to the number of electrolytic capacitors that contains and the failure mechanical devices is proportional to the number of moving parts it contains. Both say the same thing tomorrow electric credit capacitors in an electronic device the less reliable it's going to be and the more moving parts in the mechanical device is going to increase its time in the service department. The late model VCRs had nipped both of these problems in the butt. they had far fewer electronic components thanks to large scale integration on ICS and they had the mechanical components down to the absolute minimum so fewer parts to break. Even though these parts might not have been as strong as some of the older ones there was still a lot fewer of them to give trouble. If someone was giving away VCRs because I would not buy one but if someone was giving away VCRs and they said to me I've got five VCRs here you can have whichever one you want but you can only pick one and those five VCRs where dated anywhere from the early 80s right up to the last machines off the the line in the 2012, I would pick the newest of any of the machines I wouldn't care whether it was a fun eye or a Daewoo or a Samsung or Panasonic or Toshiba I would pick the last one. The reasons were exactly I stated above fewer electrical parts and fewer mechanical parts plus a modern machine is likely to have a fraction of the hours on the heads then say an old machine that's been in use since the 1980s. When I look around and see people asking hundreds of dollars for 30 and 40-year-old machines I just shake my head. but then I shake my head every time I drive by the local cannabis stores and see the lineup to get in! Actually I laugh at that one because all those people that are buying the legal weed are just helping keep my tax base low with all the taxes they're paying on it.

      ​@@12voltvids As a vintage VCR collector, I fully understand you and mostly agree with what you said. Although those old top loader tanks are very well-made, they are constantly breaking now. But, I love the mechanical and electronic complexity of those older units and love to tinker with them, adjusting stuff etc, and that's what got me into collecting them, plus the asthetics of the old machines are better in my opinion. I look inside a 2005 "piece of crap Funai" and think of it as a cheap and boring machine with nothing special, but in reality that "piece of crap Funai" is likely going to perform better than my 1979 National Panasonic with woodgrain and piano keys.

      I will be looking it up with my suppliers. I remember back in the day i used to change lots of those sensors. personally I would take any of the late model phone eyes or Panasonic or Sony VCRs over these old ones. Just too many mechanical parts moving around that freeze up and break other plastic parts. I know people will complain about the more modern ones being light having no wait to them but when it comes to VCRs the fewer moving parts you've got the better even if they're plastic. You just have to load them gently no slamming tapes in and trying to fire the tape all the way to the back of the machine. I used to love the old Mitsubishi machines like the hsu 65 and 67 and 82 they were great machines aluminum chassis built like tanks. same with the Sony mechanisms like the R5 and the r1000 and the 767 and the 757 they were good although middle post would seize up on them and break plastic gears if you weren't careful you had to lubricate them.

Videos are tracked exactly the same way they are for regular RUclips viewers it's just you don't see ads. You are paying for the content that you watch no different than with the advertisers supported videos. Other sites do not pay their creators unless you charge the viewers on a per view basis or you opt in for advertising or you opt in for merchandising where you are selling people something I'm not selling anything. I tried the patreon years ago and put up content specifically for patreon supporters. Out of 125,000 plus subscribers I had fewer than 100 people drawing on patreon and contribute $1 a month. There are no sites that I am aware of that will publish my videos and pay me for the views without either running advertising or requiring the viewers to pay. I tried that as I mentioned with patreon and people do not seem interested in paying for content unless it's porn. If you get offended because I tell you to f off it's because I get tired of the comments that I receive on a regular basis from people bitching and complaining and whining to me about the commercials that RUclips runs. That has absolutely nothing to do with me and even if my channel was not monetized there would still be commercials run RUclips is a business RUclips cost a lot of money to run. The commercials that RUclips runs pays for the operation of the business. Yes they do pay us for the content 55% of the advertising revenue to be exact. When you subscribe to RUclips premium the creators are still paid for views and from what I understand it's even slightly higher than the rate that we get from the address of course that depends on how many commercials get run. This time of year commercials are generally higher in count then say in the spring but as a Creator I can't do anything about the commercials and I'm not about to start posting my videos on to other sites where I get no revenue that would make absolutely no sense whatsoever. What you need to understand is that I and other creators do not do this just for fun. Some people come off with the attitude that I should be doing this just to help people. If you understood the amount of time involved in producing these videos maybe you would have a different attitude. I invest on average 40 hours a week sometimes more producing videos. This includes the time repairing products and editing and then dealing with replying to comments. If I come off sounding sarcastic and maybe a little bit rude oh well I have to listen to people bitching and complaining about every little thing. If I called that ghetto blaster I get a blaster I would have to deal with all the people being offended because I called it a ghetto blaster so I thought I would have fun and call it a g blaster or bleep out the word ghetto and then I have to deal with all the nut cases out there that are jumping all over me because I bleeped out the word I did it for fun I had probably 200 comments about bleeping it out I had to delete most of them. and the number of people that bitch and complain about RUclips's advertising it's just getting to me I have no control over it if you don't like the ads you know the solution chip up your 10 bucks a month or shut up but you don't bitch at me about it or you're going to get told to eff off because I really don't give a shit it's beyond my control and I'm not going to invest any more time uploading to other sites unless there's substantial financial gain in it for me. I've yet to find any sites that will provide anywhere close to what I make from the RUclips sites that is unless people are willing to pay to watch on other sites. From your attitude you're not willing to pay 10 bucks a month for commercial free RUclips so I don't very much whether you be willing to pay on other sites as well. since you probably already unsubscribed and you're not going to read this anyway all I can say is don't let the door hit you on the ass on the way out, see ya.

      On an average day i get about a half dozen people bitching at me about the ads. Then I get the crooks that think they are doing everyone a favour posting my content on other sites which I then have to send those sites take down requests. This is the easy part because since the original is posted on RUclips that affirms my copyright
