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.

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.

For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.

Hello kilmertwo, my names Dave! What your TV did is called the POP OF Death! In order to repair the TV you will need to replace the Y sustain & the Z sustain board also! The loud POP noise you heard came from the Z sustain! If you take this TV to a local repair shop the cost of the repair is going to be around 800.00 big one! 450.00 parts and 350.00 labor! Not only will you be spending that amount but this is a common problem with this TV! So you take the chance of this happening again! What I'm trying to do is to save you from throwing good money after bad! Do not repair the TV! You can for the same amount of money buy a totally brand new TV! I would suggest that you buy a Panasonic! Trust me!

Please feel free to contact me if you have any questions! I'll be more then happy to answer any question you may have!

SOURCE: 32 plasma Vizio VP322HDTV10A .

Hello; I am John at J D Electronics in Poland, Maine. I have now repaired 9 of this same model in my shop. The set may be dead always or work intermittently. There are 2 versions of this piece of junk, but I have only seen this one. They all have 2 capacitors that fail on the power supply board just above that red chopper transformer. The are labeled C233 and C234. These are 3300 ufd at 10 volts and 105 C temp rating. You can buy these for about $1 each from Digi-Key Electronics plus shipping. There are some cautions worth mentioning. Make sure the set has been unplugged for a day or more before starting the disassembling. It is VERY important to keep the set face down on a soft surface when doing ANY work on the set. This crappy designed set has a glass faceplate that will fall down if you don't have it face down when all the back screws are removed and it is very hard to put it back into position if it falls. The bottom plastic speaker strip has a million screws to remove both from the bottom edge. Then take out all the screws for the metal back and unplug the speakers. The connector wires to the speakers will not just pull off without you pressing on a side release pin for each of the 4 wire- Stupid design again!. If you are not able to solder these parts in , you can send the board to me for $25 labor plus $10 return shipping and $4 for the parts ( or send your own). We accept only cash or USA postal MO. There is NO Warranty on this repair. It is a better than 80% chance this will fix your set. Call me at 207 998 5687 Good Luck! John

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Vizio had problems with the processor boards.
If you had no lights, I would say power supply, Logo with lights, I would go with Processor board, check ebay. It is called a main board and they run about $60. That is what I would get, but then again, how old is it? If I could replace it with a new for $250 why take a chance for $60. I have pitched them before.http://www.ebay.com/sch/i.html?_odkw=E321VL+main+board&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR2.TRC1.A0.XE321VL+main+board+refurbished&_nkw=E321VL+main+board+refurbished&_sacat=0
