Sony wega kv-34xbr800 doesn't turn on sometimes

If I turn it on after a long period of being unplugged it works fine, but if I turn it off and try to turn it back on it will not work, until I unplug it for a few hours and plug it back in then it works fine again

When I turn on the TV, I get a light green picture that fades to an even darker green and then the TV shuts off. Any ideas of what could be causing it? FD Trinitron WEGA KV-34XBR800

My thoughts is that your CRT - Tube is going out.
May be time to think of replacing it.
There is what is called an electrical Gun in the back of the tube. This is what will emit the Green, Blue and Red electron beams on the front of the screen. Sounds like something has been damaged in this gun area.

Picture bowing in center from top down about 1 inch in middle, ok at edges, also looks as if degause is inoperative with colors on left and right (purity) --------------------------------__________________...

This is a convergence problem. Look for poor connections at the convergence ICs. Try resoldering the pins on the ICs. If that does not resolve the problem, replace the ICs.

Sony kv-32hs510 stand by blinks 6 times not abe to turn on the tv

It an over voltage or over current problem.....Turning the TV on and off or unplugging the TV may allow you to start the TV. Once started the TV may run for days until you turn it off.
The TV will require a new board to correct the problem...
