Question about Vizio VP322 32 in. Plasma TV

2 Answers

I purchased my Vizio VP322 HDTV10A just about 1.5 years ago for almost $600 at WalMart. For the past 4 days or so when I turn it on it will cycle on/off numerous times before powering up and staying on. Today, however (5/21/10), it would not power up at all - nothing, no light in front, no powering up sound, nothing. Tried several different outlets - didn't work. Tried a new power cord - didn't work. I'm now on disability since my purchase of the TV and am not able to buy a new one or take this one to a shop and have it repaired (sorry guys.. sometimes that's just the way it is.) My brother is a very good electrician, but he's not a TV repairman... any suggestions? I'm sure if it were explained in detail, he could repair it. Yes, I have a soldering unit if needed... *grin*

    I have been trying to find a place around where I live to purchase the needed parts - unbelievable! Nobody around here - none of the electronic stores - have the parts! And, they do not have comparable parts either!

    So then my question would be... what parts can I exchange out for different parts and what would part would I need? Where can I get them and what do I order??

    I'm sorry to be such a PITA, but I cannot believe none of the electronic stores around here sell this stuff... I even stopped off at a hobby shop if you can believe that and even THEY didn't have the parts... un-frickin' believable!!

    Any help would be appreciated..


    P.S. - Here are the parts that need replacing:

    C233: 10V; 3300 µF; 105° C(M)
    C234: 10V; 1000 µF; 105° C(M)
    C236: 10V; 1000 µF; 105° C(M)
    C204: 25V; 1000 µF; 105° C(M)
    C205: 25V; 1000 µF; 105° C(M)
    C238: 10V; 470 µF; 105° C(M)
    C241: 10V; 1000 µF; 105° C(M)

    Those are the bad capacitors and need to be replaced. I cannot find higher voltage capacitors with a higher temp. threshold. I cannot even find capacitors with the same voltage, but a higher temp. threshold.

    Any help would be greatly appreciated. Sorry this is turning into a nightmare! :o(

    LOL! Thanks for all the info.. I found a website and got all the needed capacitors.. even ordered extra (just in case I screw something up! haha).. I must be an odd-ball of nature.. LOL.. I bought some caps from RadioShack, they weren't EXACTLY the right one to fit the bill, but I gave it a go anyway, I had no problem getting the bad caps off and soldering the new ones on.. but I think because the caps I bought weren't quite what I needed, it didn't work. I can get the TV to go on, but it shuts itself off immediately.. and I think it's because the caps I bought didn't quite have the right uF ratings that I needed, but it was all they had. So, I ordered the parts online.. I didn't know I needed a desoldering gun... and that I can get (I hope) at RadioShack since I have to go to the auto parts store next door anyway and get my ignition switch I ordered for my truck.. LOL.. a girl of many talents.. hahahaha...

    I really appreciate all your help... I might be hitting you up again if I get stuck.. hahaha... if you wish, you can contact me directly at :o)

  • terrae Jun 01, 2010

    Thanks... yeah.. I didn't have a de-soldering gun when I was working yesterday, but figured it might be best to have one just in case.. am anxious for the parts to get here... I was pretty sure (but hopeful anyway) that the caps I bought weren't going to do the trick, but I tried.. lesson learned.. LOL

    Thanks for the well wishes... it's been a helluva ride! haha

  • terrae Jun 02, 2010


    Ok.. see? learn something new every day... I didn't know there was a specific way you had to solder in the caps.. will pay attention to that next time..

    Yes, you are correct, the 10V blew first I'm guessing, then the 25V followed suit. So, I have about 7 caps to replace.. I ordered the caps (more expensive these days I guess)... cost me nearly $100 with the tax and shipping added on... I looked at numerous places online... had the hardest time finding the 3300 uF caps! If I found them, then they wouldn't have the other caps I needed.. geeze! It was difficult to find all the caps I needed in one place so I wasn't ordering from multiple places... but I ordered extra caps because I might be doing this again.. who knows.. LOL

    Plus, I ordered a soldering tip cleaner, and I bought a stand for my soldering wand today at RadioShack, and a de-soldering wand also... but I am still better than buying another TV!

  • terrae Jun 04, 2010

    BOY HOWDY!! YEEEE HAAAWW... there are days when I really like being female.. LOL.. today was one...

    TV is repaired... and up and running GREAT! In fact, unless I'm just imagining things... it has a better picture! wooo hooo

    Thanks to EVERYONE! who responded and helped guide me... I *knew* absolutely nothing about capacitors, soldering, and plasma TVs (except that you turn them on and turn them off, LOL!) ;o)

    Thanks TONS everyone!!


  • terrae Jun 04, 2010

    a little determination... a LOT of guidance from others who are in the *know*... faith in yourself that you can meet and accept the challenge... and give nothing less than everything... what else have you to lose since the TV already doesn't work, if you screw it up, you are no worse off than when you started except for the little bit of money you put out in parts... I had GREAT teachers (including YouTube! LOL).. and a true desire to learn, and a playfulness to accept a challenge.. haha

    I am astounded as to how many people have had problems with these plasma TVs.. it's not just Vizio either... apparently it is all plasma TVs. As far as I can tell, if Vizio had simply changed from lower voltage caps and used caps with a higher voltage, maybe they could have continued manufacturing plasma TVs instead of discontinuing manufacture of them... then again... maybe if they could have engineered some sort of cooling system for the power boards, sort of like what you see in high-end gaming systems, as well as using higher voltage caps, maybe they could have avoided the entire situation altogether... something to think about anyway.. LOL... maybe I should have been a television engineer.. HAHAHAHA (uhhh.. yeah, right!!

Its bad capacitors on the power board
if you can solder, you can fix it.
look for caps that are bulged up, theyre supposed to be flat on the top. google bulged caps and youll see pictures
replace with same value parts to solve, all are solder in

    hey don't sweat it, electronic parts are almost impossible to find locally. you need to find them online - i usually check companies like - digikey, mouser, jameco, or mcm electronics. just search for the official websites and pull them up. digikey will send you phonebook sized catalogs so might avoid them, but just find the website and punch 1000u or whatever. go with 105c caps wherever you can , and you must have equal or greater voltage tolerance. if you have 10v you can put in 16v or 25v but you cant put in 6.3volt. if you need practice soldering, find a little kit, toy, or something to solder together to get the hang of it. you will need solder wick or a desoldering pump to unsolder the old parts. you should be able to find video tutorials on so check there just to see how its done quick. best of luck! oh also, you might complain to vizio since all of these tvs have bad caps, maybe they would pay of a repair since their product is defective.

    yeah too small values would probably cause it to shut down. you don't need the desoldering gun or pump, but its nice. i usually just use some solder wick, but you can even just head the connections and pull them out, just make sure you dont tear the traces (wires) on the board, or then you have a bigger issue to deal with. best of luck to ya!

    Well glad you found all the parts, and will have the proper tools to get it done.. and now you'll be ready to repair other stuff too. Let me know how it turns out or if you have any other questions. Good luck!

    excellent! nice work.. if vizio would have fixed this for you, they just send out another power board with the same defective caps on it. good job! a little determination is all it takes!

What parts do you need? It is the caps that are the problem did you solder in the correct way with the negative stripe on the cap? Which caps were bulging? my guess is the 10v and after they blew a couple of 25v blew!!

The sound on my vizio model no is vp322 hdtv10a comes on for a short time and then it goes off and the only time it will come back on is when I cut hte TV off and after a while and the cut it back on.

You may have a bad power supply, or the voltage regulators on the main board are flaky. It may be a bad capacitor, generally a visible difference from the other capacitors will indicate the candidate.

Vizio has a recurring problem with \'adjusable\' voltage regulators on their mainboards that produce the sub-5 volts components desire.

So, it is a component that is heat sensitive, has a bad / cold solder joint, or possibly the power supply capacitor that drives the sound ICs and amplifier.

Vp322 hdtv10a have picture but no sound, what board is it?

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.

I have the Vizio vp322 hdtv10a that doesn't turn on,I opened the back panel and found that the capacitors aren't bulging.

Hello, might need a Main Unit or Power Supply by the sounds of it. Try out a company named 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!

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 you are not able to hear sound during the this process, the power supply of the TV is likely failing.

If you are able to hear sound during the 3 minute ordeal, then likely the inverter for the backlight is failing, which can also be caused by a failing lamp as well.

Try this: turn the TV on, wait for it to do its thing. Goto the menus, picture settings, and turn the brightness *down* as far as it will go. Exit out of the menu (save if prompted). Turn the TV off, wait a bit, then back on. If still same issue, it could be the power supply or inverter / lamp assembly. But, if the cycle is shorter, or comes on right away, then it is likely the lamp / inverter.

I think I need a new power module for my Vizio vp322 hdtv10a tv. How do I open the TV to expose this module? There are about 10 million screws on the back of the set.

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.

No power

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

One year to the date almost now out of warrenty it wont turn on

Mine did the same thing (VP322), I would go to turn it back on after it having been off for a while, and it would turn on, then off, then on... Over time it would cycle on and off even longer... Eventually it stopped working, would not turn on and made a clicking sound.

Mine was past it's warrently, so I opened it up and inspected the switchmode power supply board (where AC connects, and two voltage ribbon cables going to screen circuit and main circuit). On the side going to the main circuit board I noticed that five electrolytic capacitors were bulging at the top (a clear sign of overheating) and when this happens, their values (in farads) tends to drop, which can cause voltage instibilities.

The capacitor values were:

2 x 25V 1000 uF
2 x 10V 3300 uF
1 x 10V 1000 uF

I replaced them with spares and reassembled the unit, and it now works.

Hope that helps!
