SOURCE: Vizio GV42L LCD TV screen black when turn TV on first time

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

SOURCE: vizio 47" lcd no picture no sound has power

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

SOURCE: I need help with disassembly of Vizio GV42L LCD TV

remove all the screws and start at the bottom and push in the tabs, and work around the edges, being careful not to pry too hard, the cover has clips all around the tv. after the bottom is free and one of the corners the cover will kind of pop off if you use the palm of your hand and lightly tap as you apply sum upward pressure.

SOURCE: I can get a 55-inch

I just casually looked at the TV in Menards the other day and the picture quality didn't look very good to me. To confirm my suspicions, I did a little searching. Conclusion: keep shopping

My Vizio Smart TV has no sound


Sounds like you may need to replace the audio circuit board. If you are comfortable with taking apart your tv, you can find a dealer on this site who provides new and refurbished circuit boards for televisions. It is a shame that your tv is so new and causing you issues. Good luck and have a great day!

55" Vizio LCD changes input when we turn volume up/down


hi it sounds like you have a software problem could be the epprom chip on the main board this is the memory chip, you could try the service mode and do a factory reset see if this cures the problem .
here is how you get into service mode Press "Menu," and then press "2," "4," "8," "9." do not adjust anything else just select reset , you will have to retune the tv in again hope it helps

47" vizio died


Very high failure rate on this brand. Even after repair, something else will fail. Cut your losses and buy a brand name set.

Vizio GV42l buzzing


Vizio makes an ok LCD, but if you notice they no longer make plasma. they stopped last year. Anyways. the buzzing sound is semi serious, it sounds as though you have a capacitor leaking. It is best to get it fixed before it goes out all the way, with it buzzing it will be easier to identify. Best of luck

I CAN TURN THE POWER ON. THE SCREEN STAYS BLACK.


This TV has 2 main circuit boards (2 LCD backlight controlers): the Power Supply board may have fried the video board on it's way out ...
You can either arange to have the TV replaced under warenty if not have it serviced. In any case best of luck with Vizio support line.

Everyone bought this TV because it was so cheap... now we find out why: Vizio cuts corners on everything from engineering to support!! All brands are not created equal. Sometimes you get what you pay for.
