I can access shopjimmy from the UK by using an IP address changing program.
So it does look like the main board.

So it sounds like the only thing I can do now is replace the main board. Once a new one is installed, will this fix the 24V going to inverter board and 18V/12V going to main board? I don't have a wiring diagram for any of these boards to see if those power circuits are passed through relays that need a switching circuit from the main board.

if you have STBY voltage but no PSon once you try to turn on the TV = You need a new main board.

Did you solve the problem?

Re: Vizio SV472XVT won't turn on

Yes I did! After the new power supply board didn't fix it, I ordered a new main board for it. Just swapped that out last night and it's working like a champ! Now I just need to verify the VGA input is working properly as it didn't pop up as a 3rd PC monitor, but that should just be a computer setting. I also noticed some horizontal lines appearing for a fraction of a second on fast motion or quick screen jumps. I believe it is just a de-interlacing issue with the 240hz smooth motion settings, so I'll just keep those turned off.
