Question about Vizio GV42L 42 in. LCD Television
I turn the tv on.....I get a blue screen that says "no signal" and then 5 seconds later the TV turns off. Pressing the menu or input button does nothing.
I fear it could be the main board. What are your suggestions?
Just hold down the input button on the right side of the tv. This is the bottom one. So,
With the tv off,
press and hold the bottom button (input)
when the tv turns on, and you see the input menu
release and press the button to put the tv into a mode that works!

FIX FOR THE BLUESCREEN NO SIGNAL PROBLEM: without powering the TV on, hold down the input button and it will reset the signal :) you should see the TV power itself on once it resets... hope this helps.

I just 10 minutes ago got done solving this problem. All together, I spent about an hour before I got it to work. A blue screen would come up with "no signal" indicated and then the tv would power off after 2 or 3 seconds. I first called vizio tech sup. and they weren't able to fix it. According to the ts guy, this happens when you press "input rgb" and don't have a computer attached to the tv. That's possible in my case because I was trying different inputs off my Harmony remote when it happened. I'm not sure which process finally fixed it, but the following are the steps I used, not necessarily in order.
--Unplug tv for 2-5 minutes. Plug back in.
--Turn tv on using remote. When it comes on, press and release "input" button several times.
--Same as above, but use buttons on side of tv.
--Turn tv on. When it comes on, press and release the input option you use to watch tv.
--When a box appears showing several input options, select the one you use to watch tv.
GOOD LUCK! P.S.--DON'T PRESS THE "INPUT RGB" BUTTON IF YOU'RE NOT HOOKED UP TO A COMPUTER!

Solution #4 got me on the right track: this is what I did to get my Vizio (42inch LCD) TV back from oblivion:
1. disconnected tv for about 5 minutes
2. turned tv on, and then HELD the "input" button pressed in for about 10 seconds without letting go. NOTE: the tv turned off as it had for days, during these 10 seconds, but....
3. The tv turned itself back on!
4. Now it's a matter of finding the right input; for me it's the "TV" input that has the signal.
--Good luck, and thanks to those that posted on this irritating issue, it saved me a bundle of cash and headaches.

I have the 32" version. Pressing input alone did not work for me. It never turned itself on. I help it forever. Then I press "on" on the remote while holding the "input" button on the TV, and that worked right away.

I got the same problem and solved it. Basically the "RGB" Input is tripped.
To solve this, you will need a computer with a serial port and RS 232 serial cable (to connect the TV RGB port and the computer).
1. Connect the computer to the TV RGB port (located in the rear panel connections) using the RS 232 serial cable.
2. Turn On the computer.
3. When the computer has powered up (you see the computer desktop), turn on the TV and before the it turns off, set the computer in Presentation Mode (you will be able to see the computer desktop on the TV screen).
4. The TV now does not turn off and you will be able to use the remote control to set the Input mode in "TV".
Hope this fix your problem.

I had this problem on my Vizio VO22L. It was giving me a "No RGB Signal" "The Power Will Be Turned Off" message when I had it in RGB mode (with VGA input from my PC). Anytime I left my PC on and turned off, then turned on the power of this unit, I got this message. I just got off the phone with a very friendly and patient Tech Support woman at Vizio, who talked to several different techs who all came up multiple things that didn't work or help. Finally, while we were talking, she came up with the idea of going into the settings menu and doing a "System Reset" to see what happens. What do you know, it worked!
To anyone else having this problem, try this. With the PC and TV on, in RGB mode, go into the menu screen with the remote (could also be done in TV mode). The far right tab is "Setup". Use the arrow keys to go down to the "System Reset" option. When prompted "are you sure" select "Yes". I powered the monitor off and on, and the problem is gone. Now if it happens again, I know what to do.

I tried unplugging the power for several minutes as well as swapping inputs, including from a laptop. Solution #3 is actually what worked. It is as easy as pressing the input button on the side of the TV. When the set clicked on, the familiar input menu was there in place of the blue "no signal" screen.

I had the same problem. I bought my VA26L at Sam's Club marked "Coaxial doesn't work" for $164.00. After reading this blog, I tried holding the "Input" button with no success. I then went into the menu and had the TV scan for channels. It found the channels on my antenna and took off. Hope this helps someone else. Thanks.

You should try resetting your TV back to factory reset. Press down the mute, 1, 8, 2 and power on using the remote.

I tried for about 45 minutes, couldn't figure this out! Finally, I called my husband into our bedroom, then he too began pushing the buttons. Then I said , let me google this. Low and behold, It directed me to your site. I did exactly as "seemo" suggested, it worked! Thanks so much!

Wow... it worked for me, too.. the technician i spoke with said some blah-blah module was burned out and that may have affected the blah-blah converter. "I Just saved a bundle on my TV repair."

Great site! My husband thought we were going to have to choke up more money to buy a new tv on Christmas! We connected the tv to our laptop with the RGB cable and changed the input. My 3 yr old had pressed the RGB input when he was trying to be helpful and turn off the tv. Thanks again for the suggestions.

I have my Vizio hooked to cable box, and I get "no signal" blue screen, too. I got help via Verizon and cable co. IF you have yours connected to cable when the "no" comes on, take the power cord out of the back of cable box, wait about a minute and re plug. The cable box will display an odd bunch of lines where the time and channel are displayed on front, it's working on reconnection. It should re -program itself, but if not, just turn cable box off with remote and then back on. The cable pic should appear again. This helped my "no signal" problem when I was just trying to watch cable and it wouldn't show. Good luck.
