Philips TV backlight turns off after some time
I have a defected 42PFL9603H/10 Philips TV.
Backlight turns off after some time, image can be seen by using a flashlight. It turns off after some time, it could be after half an hour, sometimes three hours and sometimes it doesn't turn off even for longer amount of time.
Could you suggest what should I check or what could be causing the problem?
Ist dies eine gute Frage?
