Question about Vizio Televison & Video
I have inspected the LED driver PWB for any signs of damage but found none. Would you think replacing the LED driver PWB should be the next step?

Try unplugging the TV for a few minutes (discharges the ballast/ps) then plug in and attempt to power on. I have the 42P Vizio over two years old and ran into the same problem a few times. First thought was a power supply issue, but the unplugging trick worked. Good luck.

Thanks for using FixYa. Please check the following—
1. Is Power board output +5V?
2. Is J1 (#19 in the right diagram)connector good?
3. Is DC-DC OK, check the voltage at J1 using a multimeter.
4. Is U4 (3.3V) working ok, U4 is an IC, you’ll need an IC tester or an oscilloscope to check this IC.
After checking this if it still doesn’t work then check P3 D-sub Input (on the D-board). See this schematic for details--
Please do accept the solution if the issue is resolved or else revert for further assistance.

I am having a similar problem. Try reseating the ribbon cables being very careful with the clips that hold them. On the T-Con board. Sounds like either the Lcd panel screen itself or the t-con board.
