I have jvc model number av36f802 qnd the timer light comes on but not the tv. what can i do to fix it

The JVC sets were bad for the vertical deflection ic failure, when this happens the safety shutdown circuits engage preventing damage to the picture tube, this will require a tv technician to fix the problem.

My sound comes on and the picture does not right

This could be a vertical deflection problem waiting to happen. Have the vertical IC replaced on this unit...
Seen this problem before, also have a technician check the IK kineing Bias circuits, could also be cold solder joints that do not make contact until the televisons warms up.

The high pitched sound is probably comming from the power supply, possibly due to its trying to drive voltage into a shorted component in the high voltage deflection circuits. You may be lookng at about a $250 repair. If it has been used a lot and its picture quality didn't knock your socks off, I would replace it with a HDTV set. A 37 inch LCD from Toshiba might be a good place to start and should do nicely for you.
