    I also have a vizio 42" lcd tv. One night, I heard two or three loud pops as if something had cracked. Screen now only irradically shows random noise. Sound is fine, just no picture. TV turns on/off as usual. Any body seen this or has a resolution?

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: Picture went out on p50hdm Vizio Plazma tv after loud POP

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:

  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

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 :)
