Owner here! Yes the raster got bigger as the caps warmed up during my initial test. Thanks so much for bringing this unit back from the brink of death. I'll be getting that lottery ticket in your honor. Keep on keeping on.

[@andymouse]

Yeah, well nice set.

[@arizonaalchemy7572]

Great deal on the set. Hope you Win the Lottery ! 😊

[@jaysmith179]

I bet that TV was very expensive back in 1974. Thanks shango for taking us along.

[@cashawX10]

I once saw one of these in the window of my local charity shop, late one night whilst walking home. Price tag $20. I actually pulled a 'sicky' from work the next morning to go and pick it up. I arrived 10 minutes after opening, I had already gone. My student house in the early 90's had one of these and it was the best picture of any CRT, or even flat screen tv I have ever seen.

[@scotthettel949]

Some would say that finding the tin whisker was luck but from watching every one of your electronics video's I say that it showcases unparalleled skill and deductive reasoning. You are truly a master of your craft. I have become a better electronics tech from what I have learned from you. Thank you sir. 73

WOW, makes my morning when I can have my coffee with Shango! You got me thinking, I am 73 now, I did a year in Vietnam, now granted I did take a leave and came home when my son was born after 6 months, but my wife was 9+ months along, and that was not a lot of sex but over that year, I never went to a brothel, hell the whores were brought into the hooch's for our use and I never took one to my cubical, not that I was not a horny GI but I guess my personal beliefs stopped me from utilizing the services. They say in the end one regrets the things they did not do, but I don't regret never cheating on my wonderful wife of 51 years and 4 days. She has been gone now for 3.6 years and not an hour goes by that I don't miss her, but no regrets.

[@directcurrent5751]

Condolences on your loss and definitely would not have been worth it versus 51+ years of true love.

[@chetpomeroy1399]

Indeed, sincere condolences for the loss of your bride of 51 years. Thank you for your service, Jerry! It was a national disgrace in the way you guys were treated back then, especially after coming home.

[@ricardogiampieri1408]

Excellent Japanese color tv, in Argentina we had similar, only with a single tuner on VHF (2 to 13). It reminds me of my beginnings in technical service of televisions and radiographers. Now, I am a teacher of electricity (and the electronics I left for my hoobies). Exactly, I agree with you, the first thing is to replace all the electrolytic capacitors in the vertical and the ones near the Flyback. A great greeting from Mar del Plata. ARG.

[@brunomoyano8727]

Hola! Que lindo encontrarse otro argentino, tienen canales de aire como aca en cordoba?

Wow I can remember getting a tube Sony I think it was 30 inch or 32 inch at circuit City in the early 90s it was a $1000 or so if I remember right.

[@bobbyk6585]

It's amazing that Shango still does board level diagnosis/repairs. All of my old tech buddies and the local shops refuse to perform them. I get that time is money, but skillset determines who deserves respect. The White House bit was gold, by the way.

Capacitor changing is the new ASMR.

Once again the master has repaired the machine. Last step is to rip off the tuner shield and poke a hole in the speaker so they won’t know you were the repairman ;)

[@godfreypoon5148]

Recapping is a lot more fun than finding and changing dead TTL logic ICs among dozens of square foot sized boards of a hundred or so chips each. Overstimulates the synapses.

[@BentMG]

My grandmother and an aunt both had this exact model of tv - lots of memories of watching early 80's programming on these beasts. Getting to spin the smooth dial and having to fine-tune for the brand new UHF channels that would occasionally pop up was an interesting experience compared to the notchy locked-in dial for tuning VHF

[@pcno2832]

In 1975, the FCC implemented the UHF "equality rule", so TVs had to have detents for UHF if they had them for VHF. But there was no "memory fine tuning", so you still had to adjust the fine tuning after some channel changes.

[@WOFFY-qc9te]

Ahhhh the cluncking sound of a spinning turret tuner to me is so satisfieing.

Fantastic picture. Even the small fonts look good. I had a chance to get a Trinitron for $30, but the seller said he might trade with another guy and he'd let me know. But he raised the price to $50 and it sold.

[@MrDoneboy]

"One tin whisker, ruined that TV, making me think the transistor was bad. shango does it again!

[@larryh8072]

I worked for a cable tv company in the mid 70’s. We had one of these sets on each of our trucks so that we could demonstrate that customers cable signals were good and their tv was crap. They took a pretty good beating bouncing around in our cable vans. Excellent sets...

[@TheDevice9]

Thanks for the look inside and repair on this. I have a KV1203 that's very similar, but I haven't turned it on in 20 years and I'm now a little afraid to unless I'm prepared to recap it. My set belonged to my grandfather and always had the best, sharpest picture of any CRT ever. I stopped watching it so I could watch a bigger screen and now ironically I watch nearly everything on a monitor not much bigger than the little Sony.

[@gustavoangelero4068]

Hi Shango. I have a model 1310, which I haven't turned on in years. Watching your repair.

[@ericmoeller3634]

I'm only 31 years old but when i was a kid you could find those type of tvs all the time on the side of the road and most still worked pretty good my friend gave me a Sony tv just like that but the handle was broken off i used it until it quit producing a picture it lasted a little over a year

[@moisessan1]

[@defaultuserid1559]

A friend gave up on his huge Panasonic CRT type TV due to intermittent problems after it warmed up, so he gave it to me after he got a refund from the appliance store who didn't want it back for some reason. It weighed a ton and I really didn't want a set that big but I gave it a shot since it was pretty new. I took the back off and start pressing on the bottom of the main board with a screwdriver handle. Found a bad solder joint near a power transistor and re-flowed all the connections that looked iffy. We used that set for the next 5 years because it had a great picture. We left it behind when we moved because it was that heavy.

It's too bad we don't have switches on our outlets like the UK and Australian ones.

[@stephenhall6595]

These sets were popular in the UK too but they only had a UHF tuner here of course. I have a Sony Bravia that I bought back in 2007 and it still gives a good picture.

[@ILIVEPLAYSTATION]

This is my second favorite trinitron, my first being the original :)

[@edwardallan197]

Just listening and following along with Shango? I finally "get" how tubes work, how current and polarity POTENTIAL (not flow) affect tube performance, how a carrier frequency allows regenerative amplification. And many more ideas I had struggled with. Endless illuminating fun here. ❤

[@greendryerlint]

This is the TV we had in our kitchen when I was a kid. It ran until the mid 80s as I recall, then I think the picture tube started failing. Great set that had a sharp picture for many years.

These are tough sets. In 1980 we bought this model from a pawn shop for $125.00 NEVER had any problems with it. My little brother still has it now. Like you said, " Don't leave them Plugged in. " It has been a Great set for only $ 125.00 ! A day on the work bench Spoiled by a WHISKER...

This was my family color TV set in New York City during the 1970s....

[@LaLaLand.Germany]

I have a 10something pal set, this and mine look quite similar but I think mine is 1st gen Trinitron, early 70´s, 240volts. It still kinda worked when I tried it but it had funky coloring, a bit like if I held a magnet next to it. But after this I think I can do it. Boring parts change is right up my alley. I´ll look into it, it is quite uplifting being able to state "I fixed a TV".

[@carolriley9392]

I still to this day, find myself diagnosing dead am circuts on zenith transoceanic radios by removing the germanium transistor and if its shorted to test leg, tapping it with a screw driver and most of the time will be just enough force to remove a small whisker from inside the transistor. Crazy, but it works.

[@jamesatkinson6480]

I might well have got rid of the 'tin whisker' in using a toothbrush around the 'sensitive' area of the circuit board. I worked on several of these sets in the 1990's, and the Sony Trinitron with a good CRT gave a very clear picture after replacement of deflection electrolytics. In Australia, several of these models incorporated a 'switch mode' power supply, reliant on a horizontal pulse to maintain operation, and with a 240V AC mains supply, giving a +B of 135 V, with a few other low voltage rails, where electrolytic capacitor replacement was common. You have done very well to come to a very rare diagnosis, as I remember thinking that the 'tin whisker' was something that just occurred internally with (ageing) germanium transistors...

Hi shango. This comment has nothing to do with this video but I found some useful info on the t291 India radio that failed the am test. It would seem that one of the electrolytic capacitors that says 1 microfarad should be 10 according to the Sony schematic this drastically make the a.m. band sound so much better with less distortion and possibly less bleed through from other stations thanks again for all your videos
