Hi, I had the same problem on my Samsung.

I removed the rear cover and cleaned the cooling fans, there were (2), it has worked fine ever since.

Be careful of course working with electrical boards.

SOURCE: Vertical Black line 3 inch width on Plasma Samsung 42C96HD after 2 months of use

On al the plasma tvs there are control boards on the lower part of the screen that control the vertical images. If one of the chips on one of the boards fail, have a bad connection, or no ground it will result in a thick black lne down the screen. Seeing as the tv is new I would get the warrantee repair on it. There is a possibility that there is a problem with the screen itself but more than likely its the boards.

SOURCE: LG RU-42PX11 42 plasma TV has black bar

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.

I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!

SOURCE: Westinghouse SK26H240S - Sound works but no picture?

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

TV picture fades, then shuts off


There are some components in the scan amplifiers, and or the power supply area that have become unstable. This can happen with age and use. It is impossible to make an accurate assessment without actually troubleshooting the set.

You need an experienced TV service tech that is strong on troubleshooting, has the service manuals, and has the proper set-up to work on your set. I would recommend the factory service rather than an independent service tech unless you know for sure that the independent service tech can handle this type of repair.

Considering the age of the model of set that you have, I would be looking at replacing it rather than fixing it. Because of the age of the set the reliability will be decreased.

Picture faded to black, came back, faded again and had stayed black.


It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.
