Question about Philips 42PF7320A 42 in. Plasma HDTV
I purchased this TV in 3/05 and it has been a fairly decent piece of equipment. Lately I have had issues with the screen , hoalf of the screen will go black, usually the bottom half. If i tap it it sometimes comes right back. I am wondering what could be wrong and what would it take to fix it properly.
Intermittent loss of picture on either bottom or top half of screen is specific to y buffer boards located on left side of screen going from top to bottom when looking at back of tv. the y lower buffer would be the board to replace to resolve the loss of bottom half of picture. if the top half also is going out intermittently could tied to upper buffer as well but just a note the y main board to right of these buffers drives those two boards so in some cases could also be part of the problem. if only bottom half is affected i would recommend replacing lower buffer only
