Question about Flat Panel Televisions
A black thin band has started to drop from the top of my acer TV screen, it runs across the top of the screen and drops down the the middle . it is starting to get worse, does any one know what this is & how to correct it , all other aspects of the TV work fine and the black band is not a physical thing it is part of the viewing section of the screen.but should not be there.
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.
