Question about LG DU-42PX12XC 42 in. Plasma HDTV

Red line a 2 inch wide vertical red line appeared the left part of the screen today. the tv is 2 years old and i browsed the knowledge data base which indicated a scan/driver problem. can someone confirm and does this mean the tv needs to be replaced or can it be repaired?

Thanks for all the input I have received. I bought the TV at Best Buy and bought an extended warranty. The technician came out and said it was a 'buffer' problem and that he will order a part (assume board) to fix it. So far no fix. Stay tuned.

I experienced a similiar issue. I have a 1" red bar running vertically about 4" from the right side. After several hours of troubleshooting, I called LG. They recommended I take it to an authorized LG service provider. They attempted to fix the issue with a replacement board. (not sure which one) No resolution. I was then informed that the issue was with the display panel and to replace that was not cost effective. Basically buy a new TV. The TV is only 27 months old and of course out of warranty. I called LG to voice my disgust with a $3K product that is dead at 27 months. ($3K when purchased) With proof of purchase they quickly extended my warranty one time for parts and labor. They redeemed a little of my faith in LG with that gesture. I haven't received the TV back yet. Fingerscrossed......

As you said, this is a scan problem, but maybe not from the 'board' itself but maybe the flex cable. sometimes it becomes loose and it makes a bad connection between the panel and the board. if the tv is under waranty: please call LG service customer they are very friendly and thay can give you a reference number that will get you a free repair in an authorized LG service center... anyway thats the way we work around here (qu?bec,canada). let me know

I got multiple thin colors on the middle of the screen

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

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..
