My Philips 42" plasma tv screen often goes black, sometimes only the bottom half. When I tap the side of the set, the full picture returns but the problem returns...... any advice/suggestions?
I bought this tv in april 2008. Today is July 24, 2008. I was watching tv, when the screen started to slowly go black. As if, black curtains were being coming towards the middle from all four sides of the screen. While the black was closing out the screen, a loud buzz was the prominent sound being heard. I tuirned off the tv for a minute. After turning back in, I saw the black engulf the rest of the screen. At this time only seeing black. Audio going, yet, the loud buzz was still the dominating sound. I turned off, unplugged for a half hour. Returned with the same result??????

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.
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
