SOURCE: 32'' Vizio LCD no picture or sound

Your filter capacitors have popped due to diodes shorting, P-channel FETs shorting from gate-to-drain. Pull-up resistors have changed value and as a result your capacitors have peaked (popped)....so now the tv is in protection mode to prevent further damage to your tv. Take it to your local shop for servicing, or take it back if its under warranty......

SOURCE: The LCD screen is dark with no sound or picture when turned on.

I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

Loud pop is usually damage to one of the boards that drive the screen--inverters or T-con type boards.

Not likely to be a do it yourself repair.

Dark band at top of screen...now whole screen


Pop sound is probably the Lamp or maybe the color wheel. When you unplug and try it on do you hear a whirling or winning sound ? Is it followed by a slight ticking sound ? If you get the whirling and a ticking sound it's probably a bad lamp. If you don't hear the whirling sound you may have a bad color wheel. The parts are both made of glass. The pop you heard was one of them breaking. If you can't tell, order a lamp you will need to change it eventually anyway.

Vizio tv first screen had bluish discoloration and than few days later a pop and screen went black .ANY IDEA OR SUGGESTION all of the sudden started experiencing severe discoloration


This is called the pop of death! If you call vizio they will ask you if you heard a pop, this is a common issue and unless your under warrenty your looking at 916$ to fix it. (assuming you have no sound! If you do its 430$ plus tax for parts and repair. You can buy a used one on ebay for that price!

I have the parts numbers if you want them!
Call vizio if you have had this system for under a yr the will fix it free!

As for me my 50 and 42 inch had this issue and well I am out of warrenty.. I hate vizio lol!

Hello SuziCanevaro,

This may have been the sound of electrolytic capacitors exploding. I would not suggest plugging the set back in until you can have it checked by a qualified TV technician. If you are skilled in Electronics and would like to work on this yourself, you will need:

The schematic diagram, a multimeter, a signal generator, an oscilloscope, and an isolation transformer.

I hope this helps,

Thank you,
