Coppell TV Repair LLC offers you functional main board for Vizio M50-C1 LED TV as shown on the picture. Vizio has several different part numbers for different batches of the board. That is, the numbers listed in the title are not all possible valid numbers – there is no space for more and we can not be certain we know all of them anyway. Upon receiving and installing the board to satisfactory results you can return the old defective board for which we will pay you the amount stated in the title of the listing, subject to the below terms and conditions. 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 contacting to power, the LED indicator lights up, stays white for 1-2 seconds and then slowly fades away; upon attempting to power on the TV (button or remote) the indicator lights up again, then fades down again. Same as above, but the TV may not respond to power on at all. The TV may be totally dead, no front LED indicator whatsoever. Note this can also be caused by a failed power supply. Make sure it outputs standby voltage to the boards or just assume the risk of incorrect call. Loss of HDMI ports or loss of audio output. REPAIR SERVICE OFFERED We may offer repair service for the times when we are out of this board. Search for it at our web site for details. For the record – and as can be seen in tens of videos in our YouTube channel – about 80% of all boards we get sent back arrive in good working order. TRADE-IN CONDITIONS FOR THE OLD DUD 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; electrical failures are OK, but custom repair attempts usually are not.
