Tv problem

Check its horizontal output section circuit for any loose solder terminals. Resolder all suspected solder terminals by applying little more fresh solder. Replace the horizontal output transistor. If this transistor have some leak, it will overheat within minutes will shut down the picture.

I turn my tv on the picture and sound all work and after about 20min the picture goes to a black screen and I still have my sound. I turned the tv off wait about 5 min turn it back on the picture come on...

If you have electronics experience - check the power supply and make sure you are getting the correct voltage to your inverter boards and main av board - also do you see any movement on the screen take a flashlight and shine on the screen - if you can see a dark image on the screen check inverter boards and power first.

thanks,

michael
