Question about Televison & Video
I have a philips 50pf9631d/10 and while the TV is working ok, picture is gone and only audio remains! If i turn off the tv and turn it on in a while picture comes back only to stop again after few minutes. Sometime the tv works for hours without interruptions though..
Bad power supply or backlight inverter.
If the backlight is not turning on, you should be able to see the lcd image by shining a bright flashlight at the screen.
Backlight inverters are loud, so you can hear them operating (high pitched whine) and if the backlight is coming on, you can see white light leaking around the edge of the screen, and even a little inside the cabinet.
Philips are legendary for having power supplies that fail due to bad capacitors, so that could be the culprit as well.
