SOURCE: vizio 47" lcd no picture no sound has power

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

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.

Why does my vizio tv only stay on for a few seconds before the picture goes fuzzy and the tv makes a very loud screeching noise and shuts itself off


Sounds like the power supply board has gone out. It can probably be replaced, but only by someone qualified to do so.

TV displays RGB code and then displays, no signal and then shuts off. What does the RGB code mean?


It means the source is not set correctly. Switch the source to input 0 (cable or antenna depending on your particular set up).

Will lead you to the manual and quick start information if you need more specific instruction.

Vizio 42" lcd powers up with sound only - no picture


It sounds to me that the unit has a faulty inverter board which could be due to an overheated/bulged capacitor. I would send in a claim on it to the factory if it is still under warranty.
