46PFL9706T - screen sometimes goes black
I have a Philips 46PFL9706T (from November 2011) which sometimes behaves a bit badly. Sometimes it does not respont to the remote (hard to both turn on and off).
But most annoying: Quite often it "flickers" by temporarily turning the screen (and the ambilight and the sound) down for a second, before going back on again. This topped itself today, when the screen almost went completely dark (could faintly see the menus if I turned the menus on with my remote) with no sound. Ambilight, however, was on and changed (so apparantly it got the input from my DVR).
Is this a known problem? Is there anything I can do? Or do I have to return the TV on Guarantee and wait (im)patiently for it to be fixed?
