Basic Troubleshooting Help if your Vizio LED TV has a blank screen and no ... It is on an UPS but turned off ...

The problem is most likely with the power source and can be fixed. However, it is best that you return the TV to Walmart for an exchange, rather than voiding your warranty and trying to fix it yourself.

HERE'S THE FIX: I just went through this with my Vizio VX37L. TV is stuck in RGB input. This is the fix.... TV is stuck in RGB input.
(option 1) Power on TV, and press the INPUT button repeatedly and rapidly until you can change to a different input, such as AV.
If that doesn't work, try:
(option 2) With the TV off, press and hold the INPUT button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. The TV will no longer be locked, and the INPUT button should function properly after that.

Option 2 worked for me!

verify if it only happens on the antenna/cable input and if it works fine with dvd or other input, then it is a signal issue with the cable or antenna u r using and repair that problem and not the tv

something is wrong call vizio i bought the same tv two days later all of the color on the screen that should be black is green called repairman who came tv was working and after he replaced the mother board and daughter board tv was black turned on but no pic he tried again and i heard the arching sound he zapped it i was told by repair we need to order the power board it willl be another 3 to 5 days
i called vizio the minute that he left i was so pissed and that is not like me they are sending a new tv that was thursday i still have to wait 7 to 10 days but they are standing behind there tv i will give them that

There may be some components failing in the power supply or one of the circuit boards that are causing too high a current pull.

I realize that this answer is very vague. Without doing proper diagnostics, it is impossible to guess at something like this.

Out of warranty repairs on these sets can be very expensive. I would suggest that if the set is going to be expensive to service, it would be best to replace it with a known brand name that offers an extended warranty with local service. You will pay more, but you will have dependability and better quality.

Go to Vizio website and buy the extending warranty, you need to have your TV replaced since the problem is with the screen itself.

Bad capacitors in the power supply. Open it up and look for swollen electrolytics.

Call vizio asap they will have a tech come and fix it free.. after the manufacture warrenty runs out they want to charge you 6--$ to fix it here is the number! 877 698 4946

I had this same problem. Vizio sent someone out to replace the motherboard. It didn't fix the problem. Since it was under warranty, they replaced it with a newer model VU42L. Doesn't have this problem, but it has others.
