I have seen this caused by 2 different problems. The vertical output IC could be bad but it is usually the CXA jungle IC that fails to cause this. Either way the set should be serviced by someone experienced in repairing Sony TV's.

Bottom half of screen is black


The display strip is not properly seated in the connector base. That is a hardware problem so dont think of a software error.

My JVC model AV-20F476 has a black-out box that covers most of the bottom half of the screen.


Go into menu and under CLOSED CAPTIONS look to see if TEXT is engaged---if it is set to text 1 turn it off or to text 2,3,4, etc

Text was a feature never really used but it is there, some cable boxes also have this setting/feature.

Let me know if you have questions.

Phillips 42 inch Plasma -Screen Issues!!!


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

If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
