TV won't turn back on

I've got a Sony Trinitron color TV (KV-G21S2). It's about ten years old and has never had any problems until now. Last night I turned off the power at the wall socket while the TV was in standby mode. This morning I turned the power back on and when I tried to turn the TV back on it would not turn on. The standby light was not on. I tried to turn the TV on with the remote and also by pressing the button on the set with no success.

The TV was working perfectly before I turned it off last night so I'm very puzzled that it would suddenly stop working.

    The model # I entered is correct. The date on the TV's instruction manual is 1997. I am in Australia, so I'm not sure if we have different models to toher countries.

The picture has a green tint to it on all channels

The color signal consists of Red, Green and Blue. Those three colors, at various degrees, make all the other colors on your screen.

If you have a BRIGHT green screen it's best you don't operate your set.
If it's just tinted green then there is a problem on the CRT (Cathode Ray Tube) drive board. Do check your "tint" setting and see if someone misadjusted it. If that isn't it then you need to have your set on an electronics bench and get an estimate for repair.

Green screen and distorted picture sound is good but no picture

It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Sony FD Trinitron Wega model KV-34BR800

Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.

Older Sony Trinitron (over 10 years old)

My experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Be careful on buying a new one though. Often times, they are much worse. Always Google the model number of the set you intend to buy and add the word 'repair' or 'complaint' to see if it is one of the many models that are customer service nightmares being produced by even the most reputable companies today.

Picture goes on and on constantly

I have the same problem. Picture cuts out completely then back on. When I first turn it on, it does this constantly for about 15-20 mins, then about once every 30 mins or so. The sound is fine, but the picture just flashes on and off.

The color is also starting to shift a lot and cannot be fixed by adjusting COLOR-BRIGHTNESS-PICTURE in the video control menu system. Nothing seems to correct this. I've even unplugged the TV over night to see if it needed some sort of reset. Model = KV-20FV12. Purchased in 2004

My connection is a direct cable connection - Comcast cable. Same problem persist while showing a DVD as well.

Sony trinitron KV G21S2(i think)

Id you have no TV repair experience, play it safe and take the set into an authorized Sony repair place to estimate the cost to repair. Yes I know it would be nice to repair, but how much do you know about component level printed circuit board repair? You will need to first get a service manual, know how to read a circuit diagram, thats a schematic, and know how every circuit works with each other to make the TV set operate. I do appriciate the fact you would like to repair this yourself, but there is no magic fix in most cases when it comes to electronics. There is circuit diagnosise involved. Best advice would be to call in a pro to assist you in these types of repairs. Good Luck
