Vizio xvt553sv reporting m470nv main board

[chandan7]

Hi,

My Vizio xvt553sv recently stopped working after a power surge. After asking for help in this forum, I found that the mainboard needs replacement. I bought a mainboard with the exact matching number 3655-0122-0150 which the seller specified is for Vizio XVT553SV.

However, after plugging in the mainboard the TV I am noticing several issues.

1. It does not boot up in one go. First it boots up for a long time then turns itself off and turns back on. And after the second boot up the TV stays on. The whole cycle takes a long time and happens everytime I turn on the TV.

2. The TV is unable to detect my bluetooth remote. I tried pressing the record button + green button, but it could not discover the remote. I also tried the "hold down the Q, P, and Spacebar" thing, still nothing.

3. The wifi does not scan anything.

4. While the board has 4 hdmi and 1 side hdmi ports, the OSD when pressing "input" only shows 3 hdmi and 1 side hdmi

5. When I check the system info in help, I noticed something strange. The model on the mainboard reports itself as m470nv.

How is that possible? The mainboard does have 5 hdmis and the number is correct on the mainboard for what it should be for xvt553sv. Did the ebay seller somehow flash the wrong firmware on the board or change some chip?

Please help!

Thank you for the prompt reply @budm. So there is nothing that I can do? Flash a new firmware or something?

sound like a factory programming error, you can confirm this by removing the metal shield on the main board to look to the flash memory chip. Vizio mark these flash memory chip with a color marker like white, blue or red.

in your case just return the board back to the seller.
