Unit powers on and only has a grey screen. "Vizio" is lit white at the bottom. NO controls work on the side panel, or remote to change anything. All we were doing is changing from TV to HDMI5 Input.

SOURCE: 1 yr old VIZIO SV370XVT completely went out 45 min

When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.

For the 46" TV, it sounds like the main board is bad.

For the 50" Vizio: is the LED light on?

What might be the problem on my Vizio XVT373SV HDTV that will not turn off and on properly?


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Vizio e322ar won't turn on


My Vizio E322AR White Vizio Light comes on when plugged in, then slowly fades to "Off". I unplugged and replugged - same. I held down the power botton on the side, and plugged in... same. Vizio light comes on (White) and over 5 seconds or so... fades out to nothing.
Remote doesn't do anything, buttons on the side don't do anything.
Going to pull the back off and look for bad Capacitors, and test fuzes for continuity. Wish me luck ... will report back later with results.

Vizio has sound but no picture.


Hello
The T'Con board [Timing Control Board] has damaged. This board can be located at the bottom side of the LCD panel. You have to open the tV, to take it out. There is no repair to this board, and only card basis replacement should be done. OK.

Vizio GV42L 42inch LCD/HDTV


there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at kmarlin@grandvalleygolfclub.com. thanks, keith

I went to turn on my Vizio and the scrren was


Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.
