When I go to turn on my Vizio 32' Model VP322 HDTV10A, it half turns on then back off, repeatedly for 3 minutes before turning on. How can I fix this problem?

If the problem is same with different input devices and you have ensured the are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

Hello, might need a Main Unit or Power Supply by the sounds of it. Try out a company named ShopJimmy.com for parts. I have used them with great success in the past. I included a link to their site from your model page. Hope that helps!

Hi,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where.If otherwise,
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


I hope this will help to rectify the problem, and do take care in handling the TV, because it contains high voltages...

Bad power supply, most likely. Take the back off and look around to see if any capacitors are bulged out. These need to be replaced with the same farad value, most likely 1000uF, but the voltage can be increased a little if need be.

Video demonstration.
You can get these parts at Radio Shack, or on Ebay. Just see which ones are puffed and match the value.

This is a powersupply. The capacitors are the ones with the + marks in the center of the circles.

When you say the "vizio is still lit up" do you mean you are seeing this on the screen itself or some where else on the set?

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.

Remove the 4 screws holding the stand. Remove all the perimeter screws. Remove all the screws from the bottom speaker panel and the rest of the perimeter screws and the ground wire screws at each speaker. remove the screws on the surface of the back panel and you are in. The power supply is the large board in the middle. The bad capacitors are in the secondary and were C233, C234, and C236. I replaced these 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.

Most likely the power supply board. Have a repair shop check it out.
