SERVICE DESCRIPTION – PLEASE READ IN FULL! Coppell TV Repair LLC offers a REPAIR SERVICE for Vizio M60-D1 main boards XGCB0QK024020X / XGCB0QK024030X / XGCB0QK024040X as shown on the picture. REPAIR SERVICE means that you need to send us your malfunctioning board that we will attempt to service, test and return to you. We may also offer serviced and tested boards with trade-in / cash-on-return (CORE) option for old duds. See store for details. HOW DOES IT WORK This is a flat rate testing and repair service, meaning we will attempt to repair any problem with the board within that price as long as the board we receive meets our requirements (see separate section below). Depending on what we find out and what we do you pay the listed price or less (details explained further below). Following the instructions you package and send or otherwise deliver the board to us. If the board arrives in working order you will be contacted for details. If the board is bad then we attempt to repair it. If we succeed we usually send the board back without communication. 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 M470NV model we’ve seen the main board being bad more often than the power supply board. Front LED stuck on yellow and TV not responding to anything or starting yellow and fading down to nothing. The front LED indicator blinking endlessly white to yellow, but the TV never starting up. The front LED blinking for a while and then stopping just as it should; when powered on the TV would display the Vizio logo and either hang on it for a long time or eventually shut itself off and possibly start initializing again (start flashing the Vizio LED sign). 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.
