SOURCE: No picture on vizio lcd

It's likely not a backlight, but a mainboard. If you are feeling frisky, take the back off and get the model number off the mainboard and check eBay.

SOURCE: vizio vw42l, the vizio light turns from ornage to

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

SOURCE: Vizio TV 2006 vx32Lhdtv doesnt work.

I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

I have a Vizio E421VA LCD HDTV and am getting a black screen. The power light comes on, but am still getting a black screen. Does anyone have the same problem and/or solution?


To determine if the backlight driver or the T-Con board is the problem, di this. With the TV on shine a flashlight on the screen. Look for a faint picture. If you can see one then the backlight control board is bad. If you see no movement or any picture at all, the T-Con board is bad.

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.

Vizio tv has sound no picture


Hi Brenton,
You have sound and no picture. It appears to be a case of backlight failure which is common in LED TVs. The problem is technical and involves opening the tv, diagnosing and replacing or repairing the defective board. Please consult some good local TV tech. Good Luck.
