You have a bad lower Y-buffer board. On these sets it is not uncommon for them to fail. At the same time of replacing the lower Y buffer board you should replace the upper Y buffer board since they work together. This is not a repair for the novice so seeking a TV technician to do the repair is recommended.

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:

Check for loose contacts in power outlet, RC cable, jack and socket.
In order to ensure, it is not caused by the input device, connect a DVD player and see.

Hi,
I'm sorry, it sounds problem with lcd panel (screen) that is defective and causing lower half distorted image. If tv is under warranty then call number written on warranty documents for warranty cover or lcd panel (screen) replacement would cost you approx 80% of new tv price.
Hope these info will help you.
Thanks.

Download philips latest firmware here: Click sometimes glitches can be cleared with their firmware. Also this could be a sign that your vertical buffer drivers are over-heating due to a faulty Y-sustain problem. The best way to check is to remove the back cover turn the TV on and see which buffer IC is getting red hot by touching it. Be careful as the voltage levels are dangerous, get someone who's technically proficient to do that little test for you....

Screen split in half


Hello, same thing happened to my 10 day old 60ps60 and we called LG and they came out and put "pin tighteners" on the Y board. All they are are these little white plastic clips that the technician put on the connectors. It is nothing you can fix. Call LG

AKAI LCT2662N screen problems -distorted


that sounds like your LCD controller, since the LCD screen is so big, they will "split" the screen into 2 smaller screens, otherwise it would be so outrageously expensive to have one big massive lcd controller. Your lcd controller is most likely a two-in-one card though, meaning that there are 2 controllers on one board. You'll more than likely need a new controller card for your tv.

Purple and white distorted fuzzy lines running up and down and side to side on tv


I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.
