The problem is you have to remove the back (lots of screws) and the board is expensive: Part number has changed and is: 996500042147---it retails for 305 dollars----I would not buy a used or repaired board if I were you--this is the problem with all plasma sets--they only sell boards--the ones for the Philips set are expensive.

Power goes out on Phillips 55 in tv. Model 50pf9631d/37. I am suspecting power board

That would be my guess, could also be a safety circuit detecting out of range parameters. But most likely a bad capacitor on the power supply board/module.

Philips 50pf9631d/10 Audio ok but no picture

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.

My Philips 50pf9631d plasma tv turns on then red light blinks 7 times! Philips no help. Local electronics store wants $500 to fix! Set is only 3 yrs old! Please help.

Are you getting picture or sound at all? If not, you could have a very common power supply failure. If you get sound or picture, then you may have a faulty capacitor or resistor on one of the system boards

50pf9631d ambilight has gone out on one side, how do I repair it with out paying philips (or an authorized dealer) outrageous rates, for a problem that has clearly affected MANY Ambilight owners? This is...

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
