While there can clearly be a large number of failures and failure symptoms that probably can't all be listed, here are the most common ones we've seen this board cause that we've seen. Loss of audio or loss of video; loss of video is more often caused by a failed sustain board, though, for which we have separate services; still, a defect in the main board could and we have seen cause loss of image - way less often than sustain boards, but definitely a possibility. Totally dead TV; this can be caused by a bad power supply as well, but at least for the 55LE5500-UA model we've seen the main board being bad way more often than the power supply board. REQUIREMENTS FOR THE BOARD SENT FOR SERVICE.
The board(s) we receive must be physically intact and must have not been tampered with or serviced before. The advertised flat rate for repair service is only valid when the above conditions are met.Exceptions are possible and often applied for minor repair attempts, but we reserve the sole right to judge if and when we would consider a repair minor. It is also possible, depending on the condition of the board, to eliminate the second possibility and just flat our reject having to service the board.
Subject to situation and availability we may also recommend replacement of the board, again at the higher than advertised price for repair.
