Vizio light is out and no power - Vizio SV470XVT 47 in. LCD TV

Failing power supply

I would say its most likely the power supply. Quite often after a power surge this can happen. Another option could be that the surge just blew the fuse on the power supply board and replacing that may be all you need. That said, usually you will get no signs of life at all if the fuse blows.

Then it is likely the power supply inside the TV has failed, possibly a sticking control board relay.

Check out the flash light test - if you see an image then the issue is with your inverter board that powers the back lighting.

you either have a faulty power supply or faulty main board. Vizio power supplies on the older sets are pretty decent. It's usually the main boards that go. These older main boards tend to be pricey so it may be better to buy a new set.

Vizio TV model E371VL turned on ok and had tv show on ch.4.
Turned on the DVD player and put movie dvd in and closed tray.
We have done thhis numerous of times and never had a problem.
This time " HDMI " was showing on top right of black screen,
then " No Signal " came up on screen, then went completely black screen. Called Vizio, they had me power off and unplug set.
Push and Hold power button on TV for 30 sec. to reset.
Replug set and Vizio (lighted) on lower front of set lighted normally dull orange. Pushed power button on remote and when set did not come on, then push main power button on side of TV. Nothing, no White " Vizio " from orange light. Is this a power supply (0500-0412-1020) problem ? Thanks, Sidney ([email protected])

is there any sound? Did you order the exact main board part # as your original board?

this is most likely the sustainer board(s) problem. Replacing the sustainer boards should correct this problem for you. you can get the parts at vancebaldwin.com
