You have a Ysus problem. Sounds like a cold solder joint or loss connections on ysus main board.

SOURCE: 42 inch samsung plasma tv black vertical lines

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric

SOURCE: Issue with LG Plasma tv model # DU-42PX12X

Another "same probelm"

My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?

Picture covered with big block of black - 3/4 of the screen ???


It sounds like your tv may require a plasma panel, but to be sure remove the back of the tv unit and check the y-sus printed circuit board as well as the z-sus printed circuit board, check that they are getting the correct voltage and that there are no blown compoments on the boards themselves. The boards names, z-sus and y-sus are written on the board as well as the voltages are listed down the side of where the plugs at the boards meet. Good Luck. Oh , and also, check with LG that it doesnt require a software upgrade.

Hello Tiangston9.
These plasma TVs have a common failure with the Ysus boards, more specific an IC that is underneath the big heatsink. The capacitors in the power supply became defective as well.

See if you can center the picture in the setup menu. It sounds like it's just off center.

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

Model 42mf231d/17 42" plasma


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

Try the scan PCBs that run down the side and the connectors that hook them up to the rest of the system. That would be my first place to start.

Unfortunately I don't have service manuals for non-european models. What is the date of manufacture?
