Defective LED back lights strips, or damaged EEPROM on main board. I will try a main board first, if you do nor have a TV LED strip tester.

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.

could it be Ch 9's digital signal is not broadcasting right? what is your refresh rate on your tv? 60 or 120hz? if its 120hz, then its more then likely the digital broadcast, if its 60hz I think its your tv can't keep up with their signal that may be at 120hz. Make since??

Hey there, I have a 6 month old vizio 32" LCD 60hz


LCD inverter module may have encountered a failure. Most common is an electrolytic capacitor failing in the power supply. Examine the board to see if any of the caps have a bloated or raised top, they should not be swollen or leaky. If so find the replacement capacitor # on line and replace. You will require a modicum of soldering skills. You indicate the tv is 6 months old.
Return it for warranty service, do not open your tv or you will void your consumer warranty.

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

change out the LVDS cable (the cable that go from the control board to the main board) and it should resolve your problem. If your TV is still in warranty, call 1-877-MY-VIZIO and they will set up an in home repair for free.

Television will not turn on


My 47" Vizio wouldnt turn on this morning.....had a similair problem 3 yrs ago.....this is what i did and fixed the problem myself.....apparently you have to reset TV. Here is what has worked for me. So unplug tv power cord from the tv. Hold the power button and imput button together ( located on side panel ) for approx 45 sec......plug cord back into tv. Press power button on tv and voila !!!!! Tv came back on!!! I have had my Vizio almost 5 yrs. But have to call the unhelpful customer service atleast once a year.... I hope this works for you :)
