Do you know if i can use an inverter from any LCD tv, or does it have to be specific to that model? I was thinking about taking an inverter from another broken TV.

SOURCE: Screen lower half goes black/blank

The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.

Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the case..you have the above problem!

SOURCE: Picture great then goes black

has to do with the main board like the other guy said go to www.shopjimmy.com way cheap and its that one cuz was told to me by the manufacturer you call tv repair man they give you all this **** it can be the power supply or the main board bring it so we can tell you just to get the money for checking it out go to this site get it but be real careful with the screen you can do it your self i did mines aint no science.
