If we fail to repair the board we contact you with details. If you have any questions please ask before initiating the service! 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.
Totally dead TV ; this can be caused by a bad power supply as well, but at least for the M550SV model we've seen the main board being bad more often than the power supply board. The front LED indicator changing from orange to white and just freezing there, TV would need to be disconnected from AC to turn it off. TV starting up, but responding extremely slowly to remote and button commands, as a computer overloaded with tasks; eventually it may shut off or restart. HDMI inputs not working or loss of audio.
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.
