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)!
