Vizio XVT473SV

[102mm]

I just picked up a Vizio XVT473SV that's in great condition but it won't power on past the Vizio logo. when i press the power button it powers up to the logo for like 90 seconds then powers off and blinks 87 times then repeats... I'm assuming it's firmware related? is there a way to repair this? any thoughts would be appreciated..

Re: Vizio XVT473SV

OK so i found the main board for the XVT553SV that i thought was bad and installed it in the 47" and now it's working great..

The next issue is where can i get the firmware for the 47" and how can i flash it to the main board.
OR is there a way to dump the firmware from the 55" and upload it to the 47" main board.

there is a repair service offered for the main boards on ebay, but I'm not sure if they deal with issues with the firmware tho..

any thoughts?
