A friend of mine had a Sony Trinitron tv that was a console. At one time i owned a 27 inch Sony tv manufactured in 1980. They also released the Sony FD Trinitron wega
13:26 Wow, my Grandmother's house had that exact model of Atari. I would never have suspected it was a launch model. Makes me wish I had asked for it before one of my other relatives got it.
I picked up a mint condition KV-1215 yesterday for $50. It's gorgeous and is working amazingly. I hate you couldn't get yours going. I just love the way it looks
I never heard of trinitrons until the late 90s when I bought my first high-end monitor. It was so amazing, I assumed they were new tech at the time. It wasn't until a few weeks before this comment, that I realized it was such old tech!!
Well the Trinitron was not new in the 90s or even the 70s as Sony first introduced the Trinitron back in 1968! Well introduced in Japan in 1968 it came out here in the US sometime in 1969.
The add and erase buttons are adding and deleting channels. Sometimes when auto programming weaker channels are missed and not added to the lineup. If this happens, just randomly enter the missing channel number and hit the add button. If a channel is picked up that you don't watch, you can delete it with the erase buttons.
We used more 9/14/21-inch Trinitrons than I can remember - in broadcast & post production… Never saw any smoke or sparks from 1974-1987, then worked for SONY around 1991. That was in PAL markets, so there may have been US power supply issues.
Hello, I was watching your attempt to fix your television and noticed you had a t-slim insulin pump and I have one of those also nice to see another type 1 in the wild 😁 A very good video and a really good attempt at fixing your TV.
This was a fun video, thanks for sharing. Shame the older TV was beyond fixing, as you said that definitely seems like something is shorted, . I'm happy you're keeping the TV, it's really quite aesthetically pleasing. Regarding the newer TV - I had the nearly identical model to your KV-1397R (except mine was grey) and it was a great little TV. Wish I had kept it. 9:55 The 2 earphone jacks were pretty common on older Sony TVs. One of them would mute the speaker, and the other wouldn't. They are usually marked with one dot and two dots to show this. I think the idea was you could record audio off a TV channel to a tape recorder while listening through the TV speaker, use headphones and mute the TV speaker, or as you said - use 2 different headphones for 2 people. 18:17 PIN is the pincushion adjustment, it adjusts the vertical straightness of the sides of the picture.
Their was a church that used to have these on the front of the pull pit. Their was 2 of them under a glass podium, they were black and white and one of them had purple carpet on the with part. The back was exposed. It was a unique set up. 📺
Miami Vice crossed your mind too, I was just thinking you'd see that one the desk of some sinister executive or dealer of yayo. Nice pairing with the NES, I'm guessing that was the peak AV for the time, still amazes me how long stereo TV/gaming took to arrive. RF, oh I thought you'd try Composite, that was high tech bitd heh. Nice headphone jacks on the 70s set, just recently I was thinking I only imagined those in TVs, always thought that was a good compromise for one speaker electronics. Clean AV connection point system too, my first family TV got pretty scratched with screw & fork swaps during the VCR rental years. Coaxial connectors took a while to be standard too, Cable-TV push I guess, wish I could have tried UHF but Weird Al is my only reference to that world. ;) Thanks for the feature, I was curious about high end TVs from those decades. There is progress in AV connectors but slow and in several steps adding Composite, then S-Video, then Component, and eventually RGB/VGA. They each have cost variances but too bad in NA we never saw an uber connector like SCART. Anyways you tried and like you said about X amount of dollars rising to repair, there's always salvage parts. Speaking of LCD replacements, I've seen some interesting tube approximation by using a lens on the outside. hackaday.com/2021/06/16/fit-your-lcds-with-lenses-for-that-vintage-crt-look/
Older set probably has shorted SG horz out SCR on the shield. Also shorted 2SC867 pass regulator & a burned resistor in the hoz drive. Then you need to find what blew it all. Trust me, dont put a penny into it. Pink one looks good. A much better set & easy to fix. Also came in blue, black, tan & maybe a few other colors...... LFOD !
Great Video. It's kinda fascinating (a little bit strange, too... ;-) ) to see this old tech, if it's working perfectly or not. You're really one of channels that I watch regularly. You and Adrian Black have another thing in common... you're both having the same insulin pump. Are you satisfied with it? I'm using a Medtronic 640G, but I'm "on the hunt" for a new one. So, if it is OK for you I'm very interested in your opinion 'bout it. So, back to the CRTs again... ;-) The pink one is really cute... Best regards and keep up the good work!
I'm so glad you are enjoying the content. Thanks for that feedback!! I would highly recommend the Tandem/Dexcom combination of pump/sensor. Adrian and I talk about it quite often. My levels have gotten about 20% better since switching from Medtronic. Also, it was announced that they will start letting users bolus from their phone and generally have more control that way. So, now is a good time to switch I think.
70's Sony TV's were miles better than the competition. Even as a kid back then I appreciated the difference. You paid a premium for them too. The Toshiba FST range was probably the first real challenger in the mid 80s, due to their flat tubes, but Sony was still king for another decade.
These TVs needed to have voltage slowly increase to reform caps a variac would do that but an incandescent light bulb in series with the tv would be useable. I found the Sony TVs to be money pits, throwing good money after bad, usually more than one component with take out several others, usually expensive horizontal output and voltage regulator parts that were Sony only made parts, you have to be damn sure the parts are all changed at one time or else you will have a pile of original and replaced parts making a nice pile. I considered it tuition paid to learn to work with these sets. But I think I would have cut my losses once you blew out the second regulator transistor.
@@RetroHackShack That's great I got a Trinitron from the mid 90s that was in use till 2018 or so and is in storage might just take it out and see if it still works. Also just found your channel a lot of great videos to catch up on.

I worked at Circuit City in 1986. The pink set is part of Sony's designer series from 86-87, and you can get the user's manual at Sony's website. They had pink, red, blue and gray. Thy also had Betamax VCRs in the same colors. On the older set (too bad you can’t get it working) the Auto setting is to set the picture automatically (color. intensity, brightness and contrast). AFT is automatic fine tuning so you wouldn’t have to set the fine tuning yourself. Those controls on the back are for TV techs. When I went to my grandma’s house and watched TV, it was Star Trek.
I'm confused as to why you wouldn't just recap the set. 70 year old electrolytic caps could still be leaking internally even if you don't see any physical leaking. They could be turning into resistors.
I did change many of them. I just didn't show that. You will notice my parts pile grows over time. However, I did test all the caps out of circuit with an ESR meter. They were reading a bit high, but not out of spec.
Shot gunning caps is not the way to go. TROUBLESHOOT the set. Even after 40 yrs at the bench I can mess up doing it. Wrong value, wrong polarity solder splashes etc. There are a few caps commonly go in modern sets but just a few. Others keep on going. And then theres the time & $$ to change out 50 little electrolytics...... LFOD !

Because if I find another set with a working flyback chances are it will work just fine. It's very unlikely I will find a set that has a good flyback but that can't be repaired for some reason.

Could be incompatible wood grain between the 2600 and the 70's Trinitron? One was walnut and the other some kind of burled wood finish..
