TV loses picture


Sounds like your picture tube or bulb is going out. It depends on what kind of tv ( rp, lcd, plasma) it could also be a component issue.

Phillips 42PFP53320 42" Plasma TV. No picture,


Hello jporter...

welcome here in fixya..

That problem is one of the common problems of plasma TV (have sounds but no picture)..As a expert of flat panel for more than 5 years I already encounter that kind of problem many times..

Actually that problem is caused of either X,Y or Z sustain board or even both 3 boards are faulty..Because some models when the one of those boards have short circuit or bad there are possibility that other sustain board are affected..But most the problem like yours is "Y-SUSTAIN" board..

I can't find your model online please double check it it either Phillips 42PFP5332D/37 or 42PFP5532D/05

And for specific and easy way to find replacement please try to look at the part # of that board (it is usually printed on the sticker attach to the board itself..

Hope it helps and please don't forget to rate my answer..

Have a nice day!!!

regards,
Chester.

My phillips tv 50 plasma hd can't show picture


Hello,


Problem is in either power supply or - my bet - the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

hope that help out......

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.
