OFFER DESCRIPTION – PLEASE READ IN FULL! Coppell TV Repair LLC offers you functional main board for Vizio M3D550SR LED TV as illustrated on the picture. The board was serviced and tested by Coppell TV Repair LLC and is guaranteed to be functional. Upon receiving and installing the board to satisfactory results you can return your old dud subject to the terms and conditions specified in a section below. Vizio uses various part numbers for this board in different batches for the TV model. Part numbers we have seen include, but are not limited to TXBCB2K01003Q and 756TXBCB2K0. Those (or similar) can be found on a white sticker on the board and/or the metal heat sink / shield and signify the actual final assembly identification, There’s also the PCB numbers printed on the board that is used as a base for the whole assembly. We’ve seen different PCB numbers for different production batches / revisions, but more importantly, the PCB numbers must NOT be used as a reference because the same PCB can be used for different, often completely incompatible final assemblies. For example the same PCBs are used for boards for the larger M3D550SR TV model and the smaller M3D460SR, but because of other differences in the TVs the assemblies for the 46” and 55” version of the TV are NOT mutually exchangeable! This board will NOT work in any other M3D model than M3D550SR, if only because of the different LVDS output connectors (but not just because of that)! 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. Image supplied through HDMI ports is black and white. TV responds to power on command, LED lights run at the front bezel, but the screen never lights up or lights up, but with no image. TV starts up and LG splash screen shows up, but freezes there. TV comes up and has image, but the image or audio is garbled. Loss of HDMI ports or loss of audio. We prove board’s functionality with a video, so if you intend to return the board make sure to sign it with a Sharpe so you can be sure it will be that same board we show you functional (if it is, of course). 2 Your board must arrive physically intact (not broken, not cracked, no deep cuts, no ripped off components, no moisture damage), with no missing or physically broken components or traces of tampering or previous repair attempts, all with possible exception of damage resulting from electronic failure such as burned components (which we are good at identifying).

The board was serviced and tested by Coppell TV Repair LLC.

Number (suffix does not matter) is the unique identification of the revision of the board that contains the particular set of components that makes it work on the Vizio XVT373SV model. Other components would be used in other versions of the board to be used on other models. They would have the same large “0171″ number since they use the same PCB, but a different 36XX-ABCD-WXYZ number. Differences may be small or big, but as a rule of thumb you want to replace a board in your TV with the same or knowingly compatible one or you risk malfunctioning and even damage (we ourselves learned that the usual expensive way). Before placing an order you must open your TV and verify that this is the board you need. It should be used ONLY on Vizio XVT373SV models and, ideally, only as a replacement to a board with the same unique identification number.

We prove the board’s functionality with a video, so if you intend to return the board make sure to sign it with a Sharpe so you can be sure it will be that same board we show you functional (if it is, of course). 2 The board must arrive in good physical condition allowing subsequent electrical repair and reuse of the board. Sometimes when components fail and burn they also leave burn marks on the board. Most of the time such traces are not affecting the ability to restore the board’s functionality, but in some extreme cases this may be a problem. 3 The board must not have missing or replaced components or have otherwise been tampered with. There may be exceptions for any of the listed conditions, but we reserve the right to be the judge on whether your board qualifies for an exception.
