LG plasma 50 inch tv with a fine vertical black line in the center of the screen that runs from the top of the screen to the bottom


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

42 inch samsung plasma tv black vertical lines


Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric

Try to replace the YSCAN board. If not fix it, then it's the PDP Panel failure.

The plasma display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. 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. May have to go inside and see if the contact assembly is disturbed or warped or something.

If these are thick black lines, this is most likely line frequency noise entering the set. you may have a leakage from the DC ground on the secondary side of the powersupply to the AC side, or a bad filter capacitor(s). Most of the time it is the filter caps that give these types of problems. If you are connected to cable TV service, or an outside antenna you can also have this problem from an AC ground loop return. Also if there is a device such as a VCR connected to the TV and it has problems, it can cause this as well...
