Tv Switchs off automatically

I have a Sony Trinitron - KVG21Q1.

When i switch on the TV. Audio comes on then the tv turns off within a few seconds automatically. Some times there is a thin horizontal silver line in the middle of the screen. (There is no problem with the Tube, It works fine). Also none of the red lights in front panel blinks.

Hello SpyTan,

You have a vertical deflection problem. This is either caused by the vertical yoke transformer going bad or the vertical coupling capacitor going bad. It may even be one of the components in the biasing circuit that delivers the vertical deflection signal. In any event this may be causing excessive current which then causes the shutdown circuit to activate. I would have a qualified TV technician check the vertical defelection section of the TV.

I hope This helps,

Thank you,

When i switch ON the TV it automatically switches back OFF in about 2-3 seconds.


The vertical IC is faulty and needs to be replaced. Look for a small flat IC attached to a heat sink. It will be marked LA7837 or something similar. Replace that part and update this with your results. That may resolve the problem or at least get you a distorted picture which will indicate a few other parts that need to be replaced.

Keep us posted.
