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

My LG flat screen has red and blue line


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.

About two months ago my flat panel plasma tv


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.

Green vertical line on videocon 42inch plasma tv


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..

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?

42" Panasonic Plasma - Vertical red stripe 6" from left side


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?
