Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

SOURCE: Vertical Red Line

I had a bright red 1" wide vertical line on the right side of my Vizio P42HDE as well as an equivalent Green line on the left. Sometimes a Blue line would appear adjacent to the red line. Had this TV sinc Oct. 2005. Based on internet research, I opted to purchase an LG 6871QCH060Q board (upgrade to the 6871QCH038A and the 6871QCH038C). Picked the board up on Ebay for $100 + $10 shipping from ShopJimmy parts.

From start to finish, this took about 2 hours to repair. Tons of screws to remove. Took me a while to figure out that the video connection unit in the back is completely modular and needs to be removed before attempting to remove the back cover. Once the cover was removed, I was surprised that I could not see where the replacement board was located. Turns out, you have to go one level deeper and remove the audio board and digital board followed by metal bracket/cover. Once removing the metal cover, the bad 6871QCH038A board was visible. A couple of zip ties will need to be cut as well as several cable connections to get to the 6871QCH038A board. Replaced the board with the 6871QCH060Q upgrade. Make sure to keep the sticky foam rubber isolation pieces and adhere them to the new board. It did take some time to figure out how to disconnect and reconnect all the various types of cable connections. Just take your time. The power cable connector for the 6871QCH060Q board is in a different location, thus I had to reroute the cable. Reassembled and only had 2 unused screws left!

TV workd great. Lines are gone. Have a little burn-in going on where the red line appeared, but still better than forking over $800 for a new 42" LCD 1080P TV. Hope to get a couple of more years out of this Vizio.

One line I found has a general example of LG/Vizio repair manual. Not exact, but close enough...http://www.scribd.com/doc/7580885/LG-TV-Plasma-Training-Manual

No solution here.
I have the same issue... A vertical magenta line, about 2 pixels wide, appeared about 1" from the left side of my 52" LNT5265FX/XXA. Of course, this appeared after the 1 year warranty... For me it started showing up about 22 months from purchase date. It goes away when the TV warms up after about 30 minutes or so. Sucks that such an expensive product has developed this issue w/in 2 years.

If its under warranty take it back immediately!!! If not you will need to have the set diagnosed to pinpoint the problem. You could be looking at a faulty t-con/panel connection (easy fix) or a bad t-con board(inexpensive) or a LCD panel(very expensive) failure !

Vertical lines in the display indicate a failing screen. New screens are expensive and not worth the labor and parts charges to repair it. It's new monitor time.

Dark vertical lines on tv screen


If under warranty then of course use that.
This is a display problem. One solution someone knowledgeable in electronics can try.
This problem can be caused by a bad connection fitting of the flat cables on LCD controller board. Dis-connect the flat cables from the LCD controller(T-CON) and carefully reconnect them. Try the unit before reassembling the back cover. You may have to disconnect/reconnect several times to show improvements if this is the problem.
