Coppell TV Repair LLC offers a REPAIR SERVICE for Vizio main board 755.00601.0001 / 748.00606.001M shown on the picture and used in Vizio P552ui-B2 LED TV. REPAIR SERVICE means that you need to send us your malfunctioning board that we will attempt to service, test and return to you. Note: seemingly the same board is used in the bigger Vizio P652ui-B2 model. The numbers printed on the PCB are the same. However the two final assemblies are different enough – even if not visibly so – that they are actually incompatible. Use this listing only for the appropriate Vizio TV model or you risk delays and surcharges! 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. Processing itself needs to be fairly quick in order for us to make profit on the job. 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! COMMON FAILURE SYMPTOMS 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. The TV’s power LED indicator can be totally dead upon connecting the TV to AC power; note there is also a known power board failure that can have the exact same effect. We have a video in our YT channel on how to test the power board, so use that to eliminate the odds of the problem being with it before paying for main board repair! Upon trying to power on the TV the standby LED indicator goes white, then slowly fades dark over 2-3 seconds and the TV never comes up; this is probably the most common failure we’ve seen. The TV comes up, but the HDMI inputs do not work. 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.
