Plugged in orange light turno on vizio light is white no picture

Try this thread : SOLVED VIZIO M550NV NO PICTURE NO SOUND It sounds like the same problem that you have.

The power supply board has some issues with its stand by supplies which should turn the logo orange as soon as its plugged in if the logo doesnt turn orange replace the power supply board You can get the power supply board from www.tvrepairworld.com

reset the tv with the tv off, but plugged in hold down the soarce botton on the tv for 5 seconds it should click on and work. if not then there may be curcuit board issues. i found the same tv on the side of the road as somewone was throwing it out, it was leaning aganst their trash can. i brought it home. plugged it in and it went on and inediatly went to the orange vizio light. i rest it and it's been perfect ever since is my comoute monitor now...good luck i hope that fixes it for you..

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.

Your TV is going into fault protection mode. The Uf capacitors on the PSB-Power supply boards are blown. Recap the Uf caps on the PSB.

According to the manual. It says The Vizio lights white when powered on and orange when powered off.

replace the power cord, do not use tv till you replace the power cord ok, you will eventually short circuit the tv or even worse blow the internal components
