I've had my Philips 32 in LCD TV for quite some time now and recently started to experience a strange problem, after about 20 minutes of watching TV it goes to this black screen of death exactly like this one posted on YouTube. Then it comes back and intermittently back and forth.
Anyone have any clues as to what might be causing it and how it could be fixed..

Tv LCD Screen panel now is crack or broken?Yes,tv can't be repair only can be replacing the LCD screen panel itself.Sorry tv now only worth as a salvage tv only for it electronic boards for parts,that it.Because tv will cost the same as a new tv,if tv require a new LCD screen panel.
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.
