It is worth fixing but you have to replace the power supply. It is a fairly common problem with the Westinghouse units.

Check to see if you are getting 12vdc feeding the T-CON board. the gray glowing means the backlight is working.
If you are going to DIY and have proper tools and know safety precaution then please read on:

SOURCE: vizio lcd sreen fading out.

This same thing just happened to me, don't mean to awaken a dead thread, but apparently VIZIO still hasn't fixed it. I found that the solution is to restart your computer or whatever device you're connecting via HDMI, unplug the HDMI component from the television and the device, wait for it to come back on, and then plug everything back in. Rinse and repeat if it doesn't work. Took me two tries to get it to work.

I've had a rca model l32hd31yx12 and recently began to get white vertical lines after a minute they fade but certain screen changes like volume adjustments and the lines come back and fade again same thing...


Sounds like the power supply has filtering issues, in other words bad capacitors. its best to have a tv shop take a look at it. they shouldn't charge you. good luck

Insignia? 37 720p Flat Panel LCD HDTV will not


Power-cycle the unit (turn it off and unplug for several minutes). If you're unable to power the unit on successfully, the TV probably requires repairs. In home service can be obtained by calling 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada.

Vizio lcd sreen fading out.


Well time will tell if this is a true solution but I experienced the same issue. Originally I was able to get the TV to work by turning it off and back on.

After some research I notice the the Vizio FAQ mentions a similar issue for which the solution is to unplug the unit for 3min.

After calling Vizio, they suggested that under the menu option Setup, Picture, Advanced Video Features, I should try turning off Advanced Adaptive Luma and Backlight Control.
