TV has no picture, no sound just the VIZIO logo light is on the screen.


Did you check out the power supply for proper operation since both the audio and video are gone? If PS is good then the problem may very well be on main board.

When I turn on my 42" vizio all I get is the vizio screen no sound and the remote will not work to turn it off.after being unplugged for awhile (days) i tried it again and it worked fine until i shut


You will need to get a diagnosis done on the set. It could be a power supply issue or a main board issue. Your problem is between one of those two boards.

I have a 42" Vizio


Your power supply is dead.
Power supplies can be purchased online for a couple hundred bucks, and replacement is fairly simple and requires only a screwdriver.
For those less tech-savvy, you may want to start saving for a new TV.

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.

Vizio vx42l hdtv back light


If backlight went out then sound should still work. Are there any indicator lights to show power is coming on anymore? Try unplugging for 30 seconds, hit power button a few times, then plug back in and try to turn on. This drains any capacitors of power to attempt to reset (basically clearing the TV's throat).

Can also try something on a different input. If current input is composite, S-video, or component, try using DVI or HDMI connection as this uses a different board in the TV. If that fixes it, then at least you can try to replace one board instead of entire tv. :)

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
