Check its main power regulator board for any loose solder terminals. Re-solder all the suspected solder terminals by applying a little more solder. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electric shock. Instead, contact any experienced service technician, or the nearest service center.

SOURCE: Blank screen when tv has been on for 10-20 minutes

Hi jilanfa00, 
I am happy to help, we need to check the backlight inverter.

  1. Turn tv on and get to a point that you have audio.
  2. Take a flashlight and shine it on the screen.
  3. Look very closely at the screen for a very dark video image.
If you see an image you have a bad inverter, you should be able to replace it yourself. I can walk you through in chat. Let me know your findings. Lone99star

I think you have a fault on the line output stage either dry solder joints or a fault with components on the line output stage or a faulty line output transformer. If you can check this for yourself otherwise find a competant technician. Hope this helps.

SOURCE: no picture on 32" Polaroid

Your inverter boards need to be tested and serviced, these are circuits designed to control the light behind the LCD glass panel. It could also be the power supply not feeding 24volts too the inverter circuits. In that case the power board would need servicing.

Take it back if its under warranty if not get it serviced at your local repair center..

Screen goes black every few seconds but have a picture


Sony incorporates a video blanking circuit that blanks the picture out when the picture tube begins to get weak. sorry, but short of replacing the tube, there's no lasting solution to this problem. I used to have some success rejuvenating the crt, but I found that it didn't last but a few hours before the blanking circuit starts to activate again.
