SOURCE: 1/2 the screen goes black

Hi there! According to the Model Number supplied, this is a 42" Plasma. This problem would normally be caused by the bottom Y-Drive board. However it may also be one of the connector plugs which was not plugged in properly in the factory. Check where the Y-Sus Board is located. There are 2 Y-Drive boards connected to the Y-Sus Board. Top and Bottom. The Bottom one may be at fault. Be careful when removing any flexible ribbon cables as these can easily tear. Also unplug from mains before removing the cover. If the panel is 4 months old it should still be under warranty. Make notes before dissassembly. Best Wishes and Good luck, Jus004.

My plasma screen goes black on bottom 1/2 of the screen


In most cases the lower Y-Buffer board causes this issue. Unless you know how to work on a TV it is suggested that you have a technician look at the TV and repair it for you.

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.

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie
