Hi I have a Sont Trinitron... I have absolutely no knowledge about what type of tv it is. All i know it older than 10 years and i dunt even think it is a flat screen. I think the model is sony trinitron KV G21S2, about 15inches. Recently I think a fuse blew as I tried to turn the tv by pressing the main power button on the tv as it couldnt be switched on by remote or other means. As i pressed the main button I saw a small flash like explosion in the back. Now the tv cant turn on, and no light is emitted (near the main power button). What happened and is there any way of fixing it? Please reply back and comments will be greatly appreciated.
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

I am having the same problem. When I switch the tv on through the button there was a flash, and it would turn on. However I know how to read a circuit diagram and its components very well. I had a quick look but of a preliminary inspection found no capacitors blown.
The power supply seems to be pulling three amps and blowing the fuse, each and every time I put the tv on once I hve replace the fuse.
Do you know a quick fix, any idea what it could be ? Or do you know were I could possibly find a circuit diagram, or service manual.
Help please
Thanx in advance
I have a sony trintitron KV 27V55.
It worked fine and then I came to turn it on and nothing . it's as if the switch is defective. I've tried from the front of the TV as well as the remote...no response to either one.
It is plugged in...
Is there a fuse on this model? If so , where.
Suggestions?
Thanks,
Tom
