SOURCE: sound works but no picture. black screen

I've had the same problem. Usually, if I turn the TV off and then back on again, it's fine.

SOURCE: lost half of picture

This can be on the matrix drive board, or the display assembly itself. It is possible to also have a defect in the address decoding area that will cause this.

The procedure is to swap out the suspect boards to determine where the fault is, leave the working boards in the set, and then follow up any necessary calibrations that are necessary.

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?

LG DU-27FB32C has picture but no sound


check in the menu first to see if someone turned the speakers OFF--that is done in some cases if a surround system or a receiver are in use.

Also check to see if sound when a DVD etc is used via rear inputs.

My LG Plasma television DU-42PX12XC had a loud pop


Your tv contains protection circuitry that would shut down the tv if the ymain was out. If the ymain had blown, you'd have no sound and just a flashing standby light. My gut tells me you need to replace the Power Supply Board (PSB). I've seen this before and after spending too much money trying to diagnose a ymain failure, I was surprised to learn that when you have sound but no picture, the psb is a gonner. Try ebay, shopjimmy.com or discount-merchant.com for a replacement.
Good Luck!

Red line on screen


The vertical line, in my case, was due to a bad contact on the flexible printed circuit. I fixed the problem by using a piece of a rubber eraser to apply downward pressure on the flexible circuit as shown in the picture. To locate the faulty section lightly push on the flexible circuit from lef to right untill the line dissapears. 9f78570.jpg
