This video and your other Sony EV-C3 repair vid were an incredible reference! Started with 2 broken EV-C3 VTRs and a box full of family memories on Video8. Never repaired a tape player in my life, but with your videos as reference I was able to repair the tape transport and replace the caps on one to digitize those home videos. Thank you so much for sharing your knowledge!
Some schools, in Ontario at least, still teach using Master and Slave monikers. I'm a younger technician and when I was in college in the mid-2010's Master and Slave were still used but they were starting to lean away from them in favour of "Primary" and "Secondary". My current workplace did away with Master and Slave after some trouble with facilities in the Southern U.S.A. Great video. Thank you.
Your videos were super helpful! Thanks to an old video of yours I was able to fix an old VCR, the last one we had and digitize memories for my parents! I will show them later as a surprise but thank you! I was born in the era where DVDs were becoming a thing, so I had no experience with what is in a VCR, but after watching some of your content I was able to diagnose a faulty mode switch and clean it. While I was able to read the tapes, the loading mechanism is also not working so I have to put the tapes in manually, and keep them pushed down with 2 pieces of folded paper. But this is not a problem since I will only digitize the tapes I have and then I will be done with it.
I hope more people digitize their tapes as they will go bad. I'll tell my friends if they need help doing it. Sending the tapes in for digitizing is a total scam and probably won't be as good quality as an Analog to Digital converter and then a 1080p capture card.
It depends on the place you send your tapes to. Not all places are a scam like you suggest. JFYI: Those A2D boxes that you see for sale on Ebay/Amazon are absolute junk. They do very poor at deinterlacing and upscaling.
I had a few machines similar to these, VHS versions, at work back in the early 90's. They were fuss free and ideal for classrooms, hooked up to a tv set, so easy to use.
Like with me, God has blessed you with a great skill. I used to be a chemist and an, and still am, an electronics technician. May God bless you and your shop. May you have many successes. I am currently working on someone's old audio cassette player that has a bad motor. The ball bearings sound horrible and it only slowly turns with an injection of 9V. Frank Reiser M.S.
Great video thanks. I have a Sony EV-C10 but it looks exactly like the one in this video. It plays Black and white for the first about 2 minutes then turns to color and is fine from then on until I let it cool again. I bought mine few months ago from a Japan seller. Yes I will do the recap on this too one day. :) I love you soldering method for recapping, easy and effective.
I just picked up one of these to convert some old tapes, I get no video or sound but the tape seems to be playing. Do you think it could be caps or some other issue?
You need a hemostat that will grip your small components and lock, the needle nose plies you you have to hold them closed at the same time keeping the part where you can properly solder it, it’s also a good heat sink
hey do you know the value of the 3 trim pots on the head amp? i think they are 47k but not sure, just bought one of these and the pots are all smashed up.
Shootz, I have this exact sony model and the picture is scrambled with no sound. Everything else seems to work fine. My local repair shop didn't seem confident or just didn't want to work on my unit. Do you have a total list of capacitors that need to be replaced? I have been following and writing down what you did but just want to make sure I'm hearing and understanding it correctly. Thank You
#12voltvids Great video and repair! I got the European version of this little beauty with leaking caps in the head amp. It could produce garbage video for some seconds similar to this unit. I replaced all smd caps on the head amp panel with tantalum ones with taking care on the polarity (opposite polarity marking on tantalum). I checked the soldering, no shorts & good contacts. After changing the caps there is no video signal on "V out" test pin at all but the unit switches to the right tape playback speed automatically. What do you recommend to check next? Control logic pins on the head amp IC perhaps? Thank you!
Enjoyed the vid. I have some old tape machines I need to recap. Everything I have says slave and master, from Alesis to Roland. So things have changed in Canada?
100k subs now. Now just think, is just 10% were Patreon subs kicking in a buck a month then all the advertising could go away and all the whiners that complain about the ads wouldn't have anything to contain about. But in reality i have .1% Patreon subs.
@@12voltvids Congratulations, Sir! Hopefully, now the YT algorithm will adjust itself a bit at least, so that the channel can grow faster. People have discovered recently something about the community section and polls, that boosts exposure on the platform. I don't quite understand how it works, but the stuff we need to do in order to be competitive with the corporate machine these days is kinda sad, not to mention the other BS like content ID and the trolls that abuse it. But non the less, let's pop some capacitors to celebrate the milestone.
Dave does Alot of repairs if you back through his videos he's done everything from vcrs to CRTs /plasmas and even microwave ovens and fans and just about everything in between I've been able to keep Alot of my stuff going thanks to him sharing his knowledge
@@12voltvids Interesting your response, where did I say give it away. I said what would be a fair price? I am not wanting to steal it just view some memories of my children.
@@basecom70 They appear to be selling on ebay in the neighborhood of 475 so that is probably where I will sell mine at. I sold a Betamax for 400 a few years ago, and after the fella that bought it finished transferring his tapes he listed it and got even more for it. I know because he emailed me after the fact to tell me he got 525 for it! The EVS3000 I just serviced last week, the guy that brought me that one paid 300 for a broken 8mm deck. These units are hard to find that have been serviced.
@@frankreiserm.s.8039 I am trying to grasp what you are talking about and then I remembered that i mentioned that my car had the battery disconnect relay fail. This is an electric car, and the battery is 360 volts. There is a safety disconnect that disconnects the high voltage when it is turned off. There is also a 12 volt battery for the low voltage stuff like the computer. When the power button is pressed the computer checks to see you have the fob i. Your pocket. If so, it turns on the car, and closes the high voltage relay which turns on the power inverter to power the electric motors that move the car. Relay fails and car doesn't move. In the next 10 years the majority of the cars on the road will be electric. Now with Biden in power the push for green cars will be in high gear. Having driven an electric car for 10 years now i say it can't happen soon enough.
What a cute vcr, i should call you the mad capacitor dentist, pull em out :-D Those new caps look like flang-chang-wang brand, have you had any dud ones?
I have a Samsung TX-R3079WH HD CRT from 2005 and it has no chroma on composite video. Idk where to even start on it. The circuitry is so unbelievably complicated, and I don't think it uses a crystal like the old CRTs did.
The HD CRT sets did get really complex. Most of them used a 3D digital comb filter. There will be a crystal in the color demod circuit.They were far more complex than LCD sets are today, becaus enow everything is burried in a video processor IC.
@@12voltvids Here's where the mystery deepens. I replaced the main video processing board, and upon turning it on for the first time after replacement, I had chroma. I sealed up everything and put the back on, and when I turned it on again, I lost chroma. What the f***. Maybe there's a short on another board? I read online that Slimfit Samsungs were really SlimSHITS and didn't believe them. Well, I've had to replace so many crap Korean capacitors it isn't even funny, and after wasting $40 on this main board, I might just smash it and toss it.
@@walle637 If you had chroma with it apart, and lost it after assembly I would suspect a bad connection, and the flexing from the weight of the board opened the connection.
Yep, I remember when one had to put the jumper for master or slave configuration in hard disks, never thought it was politically incorrect at that time.....
There was a time when referring to native persons as "indians" was also OK. Sorry, but the only "Indians" are either people from India, or it's a motorcycle. Native Americans, First Nations or Indigenous person is the only way to address the original people of North America.
There were two for sale and I did look at them, but I had no real use for them at the time and I have a wife that throws things out if you turn your back on her. "If it is not being used there is no point in giving it house room", Even she looked at them, but decided not to get them, they were need a bit much for what it was anyway. Fine if you are transferring video to DVD, but everything I want to transfer is on VHS tape. Just the kids and some holiday things, but I can live without it anyway!
@@josegti84 I agree that PC is blown out of proportion in many cases. Some take offence to just about everything and manufactures have to be very careful about choice of names and terms as it can literally blow up in their face.
Well at least it wasn't as bad as my customer with his 2021 Toyota Rav 4. Soy based insulation attracts mice. Have chewed wires twice and caused over 800 in damage each time and not covered by warranty.
anyone that knows anything about old computers, electronics, switchers, power splitters or anything like that knows what you mean about "slave" and "master systems. It's only funny to stupid people who don't know what it means.
Unfortunately in this politically correct world terms that have been used for years are no longer acceptable. When you think about it master and slave are terms that are no longer acceptable considering the history of those terms. Host and client are better terms that describe exactly what they are.
The picture quality is as good as any 8mm player. No, it isn't a hi8 or digital 8, it is regular 8mm, and that is what it plays but, the picture quality is as good as any 8mm player or camcorder. 250 lines horizontal resolution which is 20 more than. VHS. Also the color is superior to VHS. Why? Because VHS converts the color down to 629khz, 8mm and hi8 used 729khz for color under frequency. Betamax and 3/4" umatic both used 688khz. The picture is better than VHS. You should understand the format before you comment. No it won't play hi8 but it will play standard 8mm as well as any other. A hi8 player will produce a better picture on hi8 tapes when used with an s-video cable only. Regular 8mm even when played on a hi8 player will look exactly the same. If an s-video cable is used there would be the potential forgotten crawl interference however since 8 mm only records 260 lines of definition 20 better than VHS there should not be any dot crawl interference as that doesn't occur until you get Beyond 340 lines definition. This is approximately the point where lumanence and chroma signals start to dot crawl. Since reqular 8mm and VHS don't have that frequency response to cause dot crawl therefore little is gained using an S-Video connection for standard VHS and standard 8 mm but there is definitely a gain when playing a super VHS or high 8 tape over an S-Video connection.

What are SCR's component used for in TVs, VCRs, Record players, Tape deck machines, VHS machines?
