I saw and 1990 "Sony" <<Trinitron>> and it still woked well. Some other people talled me that they are still good... maybe the one made for U.S.A. where bad...

Some is selling an tv 21" monitor "Sony" <<Trinitron>> K-20PS1 for 100 bucks. I think the price is to high for an old tv monitor like this (if it was and tv maybe I would have give him the money).

I have a mid '80's Trinitron model KV-1972R that I watch everyday. This was given to me about 4-5 years ago by a TV shop that was going to throw it out. They said lightning had struck it and the customer didn't want to spend any money on it. I replaced the bridge rectifier and a resistor and it's been kicking since then. I'm not a big fan of modern Sony TV's. It seems like the newer ones I find have either a bad CRT or flyback.

Hi you all,

I have a couple of older trinitron TVs i'm going to fix sooner or later...

One is a 1985 22 inch stereo set (i don't remember the model, it's made in the UK and has a flat protective glass in front of the screen) we bought it new, it needed a flyback in 1994, and has been our main set until 2002 when it failed again and was replaced by a 1976 Philips 26 inch set

it still works, but it would briefly display a blue screeen and shut off whenever a very bright white picture has to be displayed

The other one is a 1972 KV-1300 i've found on the roadside, the IF board has been messed up in a real clumsy repair attempt, there are some missing transistors, and a lot of makeshift handwiring and hot glue... the set is displaying a raster but of course the IF is absolutely dead... i would need a schematic for this set...

Can anyone help me to repair them?

At a repair shop they have a "Sony" <<Trinitron>> that looks almost like this one, but I think the screen is smaller (19" or 20" inch screen) and the plastic from the front side is green. I wonder if it's working only in P.A.L./SECAM, or if it's have also N.T.S.C. input. But the guys there prefere to hold it in place, rather than sell it. And in front, they had the case with the C.R.T. and some components (not all) of an samll (5"-7" I think) of an '60's portable Japanesee tv

Uh, oh, I'm an Romanian but sorry to say the Romanian have the bad habbit to desrtroy everything that is old.

Kiwik, sorry to say, but I don't think the poeple here could help you. U.S.A. "Sony" have different schematics from Europeanen "Sony". I live in Europe. If you tell me the model, maybe I can help you.

I have a really nice 25" XBR from the mid 80s I bought in a thrift store for $75. It has a fantastic picture, I just had to fix a bad solder joint on a big resister that was causing the luma to cut out. Now I'm having trouble with the color saturation fading in and out. I don't really want to get rid of it, but I looked at a nice Panasonic 42" plasma the other day ...

Anyone want to buy it? It must weigh well over 50 lbs.

Edit: telecolor, i used to know someone who had that exact set!

i'm also considering a flat panel display... to use as a computer monitor.

That may just be a dirty ACC control. I forget where it is on that set, but in the chroma section on the board someplace; the kind with a small hole to turn it from the foil side of the board. Very common problem. Otherwise, you have more cold solder joints.

The color also goes a touch green at times.... I'll have to look into it. Even though I'm picking up my new Sony 40" LCD tomorrow, I can't bring myself to get rid of this set yet.

It could be the flyback going out.

My Sister and ex Brother-In-Law bought this exact same model set around '85. This, of course, was a high end set and I know they paid a nice chunk of $$ for it. It saw heavy use for about 10 or 12 years until the CRT finally got too weak to make a satisfactory picture. I remember theirs had seperate speakers and every type of input one could possibly need. That was a time when A/V jacks were considered a luxery. Now, it's pretty much standard even on the cheapest TV's.

awww.. it reminds me of hte PVM-2030. I love those big cube monitors

Snade · #74 10-26-2007, 05:34 PM

Ok, this thread got me hooked.

I just picked up a 19" KV-1923 made in 1982.

Love the clean lines of this set and the picture quality is excellent.

Paid 20 bucks at Goodwill. It is in great shape.

Cheers, Snade

What is the best way to get scratches off of metal? The metal speaker grille on my Sony has scratches on it, I've tried brasso but it didn't work...
