A vertical line could indicate a faulty lower scan (long skinny boards along the bottom of the set) board, a faulty lower scan connection to the screen or a bad screen altogether!

SOURCE: Vertical white line down centre of Soniq PT42SH plasma TV.

One of your "X" buffer boards is defective. In Panasonic plasma tv's they are located at the bootom of the set and connect directly to the plasma diplay panel via a thin ribbon cable. The board you want to replace will be directly in line with the discolored vertival line in the picture. The part number is on the circuit board and usualy starts with "tnp..." or "txp..."

SOURCE: There is a big black verticle line on the screen

vertical lines in general are caused by the data boards (buttom of screen) theres a left one and right one these boards are atached by ribbon cables going to the logic board .first all ribbon cables must be checked and reconnected to make sure there well seated ,also pass compressed air ( can ) , if this dose not solve problem try slightlypressing on the connecters replace defective board , on many lg tvs the connecter on the logic board is defective slightly pressing solves problem ,if this does not work you have two choices the data board thats on the same side of the line is defective you may try to clean the brown flex connecters that plug to the data board these connecters are not easy to reconnect be delicat and patient !!!if data board does not solve replace logic board !

Black line in centr of Screen


sounds like a bad panel, try reseating any cables you can on the buffers . the buffers would be on the lower edge right where the black line appears. unfortunately Vizio does not supply panels.

Try formatting the memory card in the computer then format it again in the camera and see if that clears the problem. Also try another memory card but if the problem persists it probably needs a repair.
