    My 42 in. plasma tv has a vertical yellow stripe on the picture. After a while it goes away, but i am worried it may someday stay. has anyone found a fix for this or is the tv just defective? I have not yet tried to contact the store where I bought the tv from, with an extended service agreement.

    I have started seeing the same thing.....today. We bought our tv about 2 years ago, and just realized....duh, don't buy plasma. and even then make sure have a 5 year warranty. I'm struggling to find a LCD tv on tigerdirect.com with high hopes of an amazing price. which they usually do. Along with the vertical lines, has anyone noticed the red dots of death. usually means your tv is about to start loosing information in the form of black squares or more vertical lines until the entire screen is kaput. If anyone is really this, the best solution is to not buy a Plasma, and if you have try to take it back and get an LCD.

This is a result of faulty or dying dip i.c.'s on the tv's logic board.
there are several that span the width of the tv, when one goes faulty it results in a vertical line.. often yellow.
the logic board is most likely small, containing at least 1 big chip wich is the micro... contact tv manufacturer and try to get a replacement. if not there are many 3rd party supplyers of oem parts

    I might add here, plasma televisions run extremely hot wich is thier downfall and the cause of many component failures. have your tv retrofit with two120 mm 12 volt fans over the y & z sustain boards to keep them cool.. heat is your enemy. having this done will double the life of your plasma. plasma tv's are good.. thier downfall is heat and the companies refusal to provide proper cooling in thier product. find a 12 volt source and you are set..or take it to a technician like me that can do this all for you.

SOURCE: Vertical lines on plasma screen

plasma display is made of matrix of elements connected through cables through top and side... these contacts are held by pressure... maybe they would have been disturbed... Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. or maybe you would have to go inside and check if there is any problem with these contacts...

Two vertical black lines on the screen of my ps50b430


Unless someone played with the TV and disconnected the plasma display from the address buffer boards that go under the screen the prospects aren't good.

All vertical lines in all plasma TVs I have seen are operated by chips embedded in the fabric of the display as well.

When they fail they'd either short or burn open.

In the first case they'd prevent the TV from coming up, in the second they'd typically manifest as either black or a random color vertical line like you have.

This is not repairable...sorry.

The odds of this being something else is fairly minimal in my opinion.

Please don't kill the messenger...

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..
