Question about Philips 42PF9966 42 in. HD-Ready Plasma Television

1 Answer

Darkened screen I own a Philips plasma HDTV which goes into a ''ghost'' mode for 5 to 10 minutes before the picture comes back to regular. Model #42PF9966/37. Is this a serious matter?

    Sounds to me as though the TV would have to be opened up to do what you have suggested. Right?

    Yes, it tells me I have to take it to a professional. Thank you.

The problem you have described indicates that there are faulty electrolytic caps on the y or z sustain boards.Often in cases of problems like this, the caps do look a bit cracked or bulged near the X at the top. If any of them don't look fishy then you should get a multimeter, set it to capacitance mode and check whether any of the read values that differ from the original ratings on the surface or "OL" which means over load. I have fixed a similar problem in my shop for the same model. The caps cost me around 10$. There were 6 of them that had gone bad on the Y-sus.

    Yes you should take off the back cover of the tv to do this. Not recommended if you do not have prior experience to do it yourself coz the circuits hold dangerous voltages for several hours- days after the unit is unplugged from the power supply.

My Philips plasma only shows half the screen. The other half is just blacked out.


This model has PiP (Picture In Picture), find the button on the remote or check manual, this mode is most likely turned on and is being shared with one of the AV channels, or try turning on a plugged in SCART device to see if this picture shows on the other half of screen.

Screen lower half goes black/blank


The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

42" Philips plasma screen goes black


You have a Ysus problem. Sounds like a cold solder joint or loss connections on ysus main board.

Picture goes blank


What type of TV is this unit? An LCD or Plasma?

If it's an LCD, take a close look at the screen with a Flashlight and see if you can see some sort of picture (Almost like a ghost of an image). If this is the case, the backlight has failed.

If it's a plasma unit, you're probably looking at a power supply issue to the panel.
