Try replacing your video cable, if that doesn't work, try using a different input on the T.V. If that doesn't fix it, you may be out of luck with out an extended warranty.

LG 50" plasma PDP50X4 only shows top half of screen, sound and top half of screen work fine....Help!


That's a relatively easy one - you have either upper or lower Y-Sustain buffer board gone bad.

if the last chip of the upper buffer has failed you may get what you get, even that this is a relatively rare type of failure.

The same would happen if the lower buffer is bad although this is again somewhat rare for a failure for those boards.

Either way you need a new buffer board and I'd start with the lower if I were you.

I assume nobody has messed up with the TV because another possible explanation would be the two buffer boards were disconnected from each other.

The best is they are neither too expensive nor hard to replace.

Hope this helps!

Oh, here's a link with something more about those boards although I am not sure it would apply to your particular case...use it as a good educational resource, but don;t expect to have the exact problem described there:

Brand new lg plasma 60" flat panel tve has horizontal lines accrss the screen only half way up from bottom. When you go close to tv, it looks like lots of of dots.


Hello Fixya customer,

Thank you for your question.

The are a couple of possibilities here including the logic board, lower "Y" board, lower "Y" buffers, and PDP panel. The "Y" is divided into into the lower and upper half of the screen. An experienced technician can quickly isolate the fault upon inspection and verify the supply voltages.

Thank you for using Fixya, and if I can be of further assistance please let me know.

My palsma screen half is black and the other half has the picture


From the brief description it sounds like the sub y board either the upper or lower one as failed (depending on which half is black. For a plasma this is a relatively in expensive repair from a shop probably a couple hundred dollars or little more. I am not in a position to give you part numbers right now but if you want to attempt to fix this yourself i can get the part numbers for the upper and lower sub y boards tomorrow. But working inside a tv can be dangerous and you can make things worse if you are not careful, so try this only if you feel confident working on electronic equipment.

Try re-seating your upper and lower buffer board connectors. These boards run the length of the set on top and bottom. Since your line is from the top going down I would check that one. The connector will be close to where the line is showing up on the screen.

Horizantal lines while showing the picture


In most cases on a plama TV the upper and lower buffer boards will cause diagonal lines to appear in the picture in top or bottom half or sometimes both.
