Re: red line on left side of plasma bright two inches...
Either the address board or the panel has gone bad. the problem is that many times the address board is part of the panel. if it is under 2 years old you need to get with lg and push for a new panel

Hello;
I am John at J D Electronics in Poland, Maine. I have an LG TV that was
donated to me. It is a plasma model DU-42PX12X. It had 1 inch wide red
and green vertical bar on the right and a blue and yellow on the left.
These bars appeared intermittently. pressing on the control board would
make the bars go away. I have read many blogs on this problem and they
all say to replace the control board located under that huge A / V input
board ( held in by 4 screws on the large aluminum frame). The original
part is # 6871QCH038A The replacement ends with a C instead of an A
Aprox 90 to 135 dollars. This board is used on many different LG and
Zenith models and is a HIGH failure rate part. I like to know WHY
parts/boards fail and I found out why this board fails. There is a large
square IC in middle of the board aprx 1 1/8 inch square. This type of
IC is called BGA or Ball Grid Array. The solder connections cannot be
seen , since they are under the IC . This IC was not properly soldered
at the factory and that is why hundreds of these sets failed. I used my
hot air soldering station on it's highest setting to heat up this IC .
The IC must be directly heated from the top and some heat on the bottom
of the PC Board. Liquid flux should applied to the 4 side edges of the
IC prior to heating. The bars are now gone! To get to this board, remove
all perimeter screws and all middle screws of the back cover. The A V
board will hinge back to expose the control board if you unplug the
cables to the side inputs and the one to the button board. The set will
still run face down on a table with something to prop up the bottom
screen so you can watch the bars. If the set was run for a long time
with the bars, there will be some darkening where the bars have "
burned" the screen. This is perminent, but usually acceptable.
Most like likely, this is a panel issue and it will be too cost to fix.
Other things you can try, reseating the ribbon cables on the buffer boards located running across either the top or bottom or both. If that doesn't do it, replace those boards and still no luck. Panel is bad.

Hello Depending how wide the line is their could be two possible causes.
I have two questions for you.
1. How wide is the line.
2. Does it run from top of screen to bottom of screen?
If the line is thin a single strait line then it is possible the PDP has gone Bad (Panel). (Screen). The screen will to be replaced.
If the line is at least 2 or more inches wide then its a buffer board which can be replaced. LG calls this board Hand insert Boards or display driver boards..
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?
We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?
the lg is 08/05 thank you anyway frith644
