Should be a back-light problem itself. If you wish to know more about the back-light system of this Philips TV, check this link. Pull
up older posts there, either by its left side bar, or see it in Timslide
option. http://electronicshelponline.blogspot.com/
ok its possible it is the light itself which would be cheaper- or- it could be the ambilight driver- each ambilight has a driver that tells it to turn on supplys power etc-its not difficult to change-usually located on either one side and the lights all run from it or one on each side-depends- its small rectangular and you can follow the wire from the light back to where it plugs in to the driver- try shopjimmy dot com for parts
probably you got a processing unit problem, which makes your tv stopping recognizing the screen information . you should try resetting all factory default settings, if this doesn't work, you will have to take the TV to an assistance center .
I had this problem on a 42" Philips Ambilight. After reading in another forum, opened up the back, and found 2 leaking capacitors on the center circuit board (main power supply pc board) toward the bottom. Tops of the capacitors were bludged out (10v 3300uF) and leaking electrolytes. Unsoldered the old ones myself, went to Radio Shack. They were out, so order 12 on ebay for $6.63 including shipping. Resoldered and works fine. Can't do it yourself? Take the board out (just unhook the cables & unscrew it ), and take it to a computer shop or tv repair or someone who knows how to solder, and have them change them. Piece of cake!
