Question about Philips 32PF7320A 32 in. LCD Television
I bought a Philips LCD TV model 32PF7320A 4 months ago. About 4 weeks ago the screen started to go black while watching the tv. The sound stays perfect and I can still change the channel and hear the channel change but the picture stays black. I tried it with a DVD and had the same issue so it's not my satellite connection. I also unconnected and reconnected all cables a number of times but this did not help.
When the screen goes completely black, shine a very bright flashlight closely at the screen. If you can see the image, then the most likely problem is that the backlight inverter has failed.
The inverter is a circuit board that works like a flourescent light ballast. If the inverter fails, there is no backlight, and the screen is black.
Since the invertor is a high-voltage component, I would also listen for any unusual sounds associated with the failure: e.g. buzzing, whistling, popping.
To rule out some sort of connection failure, see if you can recreate the failure mode when using the TVs internal setup menu. The setup menu does not rely on any external inputs....of course neither does the volume control or channel indicator on the screen.
