OFFER DESCRIPTION – PLEASE READ IN FULL! Coppell TV Repair LLC offers you functional replacement for the main board for Vizio P702UI-B3 LED TV as shown on the picture. Vizio tends to use different assembly numbers for different batches of their TVs so there may a number of valid part numbers of this board in addition to Y8386524S. Use this board only as a replacement for the model number shown in the title and the above paragraphs! The board was serviced and tested by Coppell TV Repair LLC. 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. 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. Upon connecting to AC the standby indicator lights up and the TV clicks, then clicks off as the LED goes off. The TV may be totally dead, no front LED indication whatsoever; this is commonly caused by a failed power supply board, though, so you may want to check videos in our YT channel on how to ensure it’s not the power board that’s causing it. 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). 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 in good physical condition, with no missing or physically broken components or traces of tampering or mechanical or chemical damage; electrical failures are OK, but custom repair attempts are not.
