You reports that you've changed the T'Con board. Where is the T'Con board to a Plasma TV? There is no such board to any plasmas. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to see the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now. Pull up older posts there or make a search by typing in the brand name of the device in the "Search Box", at the top right of the display window

Ok, There are well three boards in this set that would influence such a
behavior. The culprit is the Key Pad Board. It has what is called a
leaky switch. This then locks up the Microprocessor. This will result
in the set operating like a ghost has the remote.

SOURCE: got a new T-con but no luck
is your back light constantly on when you are not changing channels.if so replace the main board. can you see a menu if you hit the menu button ? that is generated by your main board..... replacing the t-con will only correct vertical lines in the pic.
