These symptoms mean that the Tcon board inside the tv needs to be replaced. You can try re-seating the ribbon cables on the board, but that likely won't help. The board will need to be replaced. You must open your tv and get the numbers off your current board to confirm BEFORE you buy. If not in stock, check eBay or search google with part number from board.

I am here to help you. If you need more help reply back. Please be sure to click the 5 STARS or SMILEYS rating now. Doing so does NOT close the question or prevent us from continuing our conversation here. My livelihood truly does depend on your positive rating. Clicking the "bad/poor" rating does NOT do anything to fix your issue, nor does it issue you a refund.
no way to test the boards except if you have an identical working tv. only thing left is the LCD Display Panel (entire tv screen).
no but the display panel could be bad and it's killing the t-con boards you are installing.
