When I turn the tv on, I can hear it but no picture. It tries to restart itself a couple of time then it turns off. Can you help?
i have sound but no picture, if i move the tv or tap on the sid the picture comes on perfect ,but after while it goes off again, tap again it comes on
This is a common problem that shops see every day... Due to the age, size and ultimately the heat this unit generates in several of the component areas it has developed ring cracks in one or more areas. The likely suspects are the convergence amps - this unit uses two STK392-110 Sanyo built amps mounted on a large aluminum heat sink. Or it coud be the vertical Ic, which in your unit is a LA7833 mounted on a smaller heat sink.
You'll have to remove the boards enough to look underneath and see where these components mount to the foil side of the PC board. If you inspect closely enough (get your reading glasses) you should be able to spot one or more of the pins in either of these two areas that are ring cracked. Simply re-flow a little solder on those pins and put it back together...
If any of this sounds too complicated call around and ask what a shop charges to comeout and solve this kind of problem (ring-cracking) causing intermittent picture loss. It shouldn't be costly.
