Vizio Main Board

OFFER DESCRIPTION – PLEASE READ IN FULL! Coppell TV Repair LLC offers you functional main board for Vizio M3D421SR 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 TXCCB02K0010005 and TXBCB2K00603. 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 PCBs 715G4404-M01-000-005K and 715G4404-M01-000-005F being used and it is important to note that the same PCBs can also be used for other models by having different sets of components installed on the board. For example the same PCBs are used for boards for the larger M3D550SR TV model, but because of other differences in the TVs the assemblies for the 46” and 55” version of the TV are NOT compatible! This board will NOT work in any other M3D model than M3D421SR, if only because of the different LVDS output connectors (but not just because of that)! 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 offer repair service for this board. We may also offer components for this board such as the EEPROM, main processor, RAM, HDMI etc. 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). Once you receive the board and fix your TV you can return the old malfunctioning board to us to receive the advertised credit. 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, all with possible exclusion of damage resulting from electronic failure such as burned components. 4 RIGHT TO WITHDRAW – we reserve the right to refuse to sell for whatever reason.
