ITS A VIZIO VW42LHDTV10A MODEL TV
I've fixed several of these, easy fix, you will need to replace both 470uf 35 volt capacitors on the master and slave inverter boards. So you will have to replace a total of 4 capacitors. The capacitors themselves are about 50 cents a piece. The inverter boards are on the far left and far right of the set. You will have to remove the back cover to see them. If you don't have the ability to replace the capacitors, you can just order new inverter boards for $40-$60.
SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.
I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

Sounds like your Backlight Inverter Board is going out, saw one on ebay for about $55 : ) have to get the one for your model tho...

It's likely not a backlight, but a mainboard. If you are feeling frisky, take the back off and get the model number off the mainboard and check eBay.
SOURCE: plugged in orange light turno on vizio light is white no picture
possibly is the main board.

you need to check first the power supply board whether the output supply 12-24vdc for the inverter board is stable and not flactuating..you can measure the output voltage with a multitester..you get a voltage output of 12-24 with the inverter board is connected or loaded to the system.be carefull of the high voltage at the inverter board..once the output is stable replace the inverter board or you can measure the output of the inverter be very carefull..the output range upto 500vac.be carefull..if the high voltage is stable replace the lamps...tnx and good luck..
