OFFER DESCRIPTION – PLEASE READ IN FULL! Coppell TV Repair LLC offers you serviced and tested main board for Vizio E422VA smart TV as illustrated on the picture. The board identifiers that Vizio uses may vary; one example is TXACB5K05303 found on the white sticker on the board however similar sticker may also be found on similarly looking board found in Vizio M421VT. The two boards are NOT compatible and you can NOT use board from E422VA in M421VT and vice versa – first, there will be image issues due to different panels and T-CONs and second, M421VT has extra functionality such as Bluetooth remote, which E421VA does not. Simply put, make sure your TV is indeed E422VA before placing this order! 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. 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 E422VA model we’ve seen the main board being bad more often than the power supply board. The front LED indicator blinking endlessly, but the TV never starting up. The front LED blinking for a while and then stopping just as it should, but then the TV hangs without doing anything; or the TV would hang on the Vizio splash screen, stay there for a long time and then power cycle. Loss of HDMI ports or loss of audio. We may offer repair service for the times when we are out of this board. Search for it at our web site for details. We may also offer the EEPROM for this board for DIY repairs as well as other parts we’ve seen fail on the board – alone or as part of DIY repair kits. 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). REQUIREMENTS FOR TRADING – IN YOUR OLD DUD. 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. 4 RIGHT TO WITHDRAW – we reserve the right to refuse to sell for whatever reason.
