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.

SOURCE: 47" Vizio Flat screen HD LCD freezes up and remote will not work.

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??

My vizio VO47 L has a black screen and sound. I do get a light on the vizio logo on the front. I see no illumination coming out of the back of the unit. what is wrong?


Power Supply popped a cap and fried the metal resistor bank. Replace the cap C241 and solderer the resistor bank. Worked for two months then pop out again. This time the resistor bank burnt through. Bought a new power supply DPS-38cp-1a from ShopJimmi.com $56.00 Replace supply which lasted 1 year 1 day and the same thing happen. Same components. Got this TV free but its costing me time and money now.

When the picture is dark, show a torch light on the screen from a safe distance. If you can see the picture, the backlight is the problem. Anyhow, it is better to show it to a qualified service technician.

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.
