After reading several forums I took the back apart and sure enough there were two bulging 3300uF 10v capacitors (C233 and C234). I ordered two replacement caps and changed them out. After getting everything back together the stand bye Vizio light would come on/turn orange and everything returned to normal. IT WORKED!!! Unfortunately, my confidence was cut off as the Vizio light below the screen stayed white like the TV is on, but the picture goes away/turns black after 10-20 mins of operation. (Not sure about sound). There were no other visibly bulged/damaged caps on the power supply. So again hitting the forums I ran across a repair kit offered by LCDAlternatives that comes with all the following caps (C233 and C234 3300uF 10v, C236 1000uF 10v, C201 47uF 100v, C206 100uF 16v, C241 470uF 10v, C204 and C205 1000uF 25v capcitors). The kit is good, but now after replacing all these caps the display will not even turn on for the 10-20 mins like before.
My current symptoms are the Vizio light turns orange in stand bye mode, once the power button is pushed the Vizio light turns white, a relay clicks, the D104 LED on the main logic board turns solid Green/yellow, followed by the D201 turning Green/yellow blinking once/second 3x, the display attempts to turn on/flashes grey, the Y-sustain board starts to buzz like power is there, within 1 second the relay clicks again, the display quickly goes black/blank, both the D104 and D201 LED's on the the main logic board go out, the Vizio light below the screen stays white. It's almost like the picture trys to load, it can't, and therefore a safety shut down occurs? Any help moving forward would be appreciated. Or there might be a video post on here of a 32" Vizio tv flying from a second story balcony. Thanks!


Any luck with this set?
I have one with the same trouble and symptoms.
Let me know if ya find any thing,its been siting for awhile sort of gave up for awhile.

I know for sure the polarities are correct. I am wondering if I didn't damage a couple of the pads/rings/foil where the capacitor leads are soldered on the green side of the circuit board? When removing the capacitors one at a time, I started by sucking up the melted solder with my desoldering tool. After this, I heat up each lead of the cap and gently wiggle the capacitor side-to-side with my fingers until it falls out like a loose tooth. After carefully disassembling everything I am even sure to use desoldering wick. On all but two, I noticed nice complete silver rings/pads on the green side of the circuit board. There appears to be a damaged portion of the pad/ring/foil for the positive leads of C205 and C233 (could be my bad solders?). I read somewhere else online that this kind of damage is normally caused when you're desoldering components. When the caps are installed the leads are bent over so the capacitor doesn't fall out of place while the cap is hanging upside down during installation. If someone desolders a capacitor and tries to pull it out while any of the solder is still adhered to the pad, that portion of the pad can be ripped off and become damaged. Are my options to upload a flying tv video or shell out the $$ for a new power supply circuit board? If they are, I may be posting that video yet.

You may be able to scrap back on the LAN with a knife where the pad is broke ,and extend the solder to connect the cap to the LAN.

Well I shelled out the $$$ for a new power supply. Got everything put back together and I am getting the same results as the ending of post #179.

My current symptoms are the Vizio light turns orange in stand bye mode, once the power button is pushed the Vizio light turns white, a relay clicks, the D104 LED on the main logic board turns solid Green/yellow, followed by the D201 turning Green/yellow blinking once/second 3x, the display attempts to turn on/flashes grey, the Y-sustain board starts to buzz like power is there, within 1 second the relay clicks again, the display quickly goes black/blank, both the D104 and D201 LED's on the the main logic board go out, the Vizio light below the screen stays white.

Now what?
frantzray's Avatar frantzray 02:40 PM 02-08-2013
Going back the forums I found the next most likely suspect could be the Main Board ( board with all the inputs-hdmi, coax, audio in/out). Got one, replaced mine, and still same results as post #184

Talked with a guy I work with that used to fix consumer electronics for a living. He gave me this advice. "You should check Vs voltage from the power supply to Y sustain (170V-200V). Their should be a sticker on the plasma panel with values for those voltages. See if the Vs goes down when the picture goes dark. If it does unplug the Y sustain from the power supply and try again. If voltage stays on then you have a bad Y sustain loading the power supply down. Also check all voltages coming out of the power supply and see which one (if any) goes down when the TV goes into shutdown."

The sticker located on the plasma shows Va is rated at 60 VDC and Vs is rated at 195 VDC.

When Y sustain is plugged in. Set voltmeter to VDC and check voltage at the two Vs pins and one Va pin.
With the Y sustain board plugged in mine was getting 0 VDC on all 3 pins as soon as the power button was pressed. Or you could say it never got to the rated values indicated by the manufacturers sticker.

With the 9-pin Y sustain cable removed from the power supply I re-tested. This time after pushing the power button I got the following stable and continuous voltages left to right while looking at the power supply.
VS = 195.5 VDC, VS = 195.5 VDC, NC = Not used, GND = good, GND = good, GND = good, VA = 58.7 VDC, GND = good, and M5V = 5.09 VDC.

Ordered a replacement Y sustain Friday night and will have an update after getting it installed tonight.

*to check grounds (pins 4,5,6 and 8) just put the voltmeter on the ohm setting and see if there is an open circuit between each pin and the ground screw used by the power cord.

Got the replacement Y-sustain installed. Found one of the solder points on the back of the old Y-sustain (one part of the large copper coil near the top of the circuit board) to be burnt. After replacing the y-sustain board with the new one I am still getting same results. Improper voltages on the Vs and Va pins when the Y sus cable is connected and proper voltages when the cable is disconnected. Wondering if my replacement Y-sustain board is DOA? Or if the z sustain could be causing similar results. Waiting for further troubleshooting procedure.

Plasmas can be very difficult to fix, esp if you are not already knowledgeable in ohm's law, multimeters, troubleshooting etc. Anyways, it looks like one of your boards is shorted to ground.Unplug the TV from the wall, make sure everything inside the TV is connected, and do a resistance check between every power pin (Va, Vs etc) and ground. They should all ready near infinity. If one of them steadily reads below 10 ohms, that board is either shorted or it is feeding a shorted board. You'll have to start disconnecting things to narrow it down.

It sounds like your y-sustain is driving a shorted y-buffer board. You can inspect the y-buffer board by doing a careful visual examination, normally when the chips go (vertical series of square ones on the left hand side) they short and the chip's casing is breached. The old y-sustain is probably toasted from trying to drive a shorted buffer, and the new one may already be damaged as well.

The thing is with these plasmas is that there is so much high current, high voltage and interconnection inside the set that when one board goes, the power surge usually takes out others or they become weakened and fail soon after. Normally the Y-Buffers/Sustain go and both have to be replaced, most people will look at the price tag and scrap the whole set.

I think these are all the connections coming off of the Y-sus. I will get a better pic and descriptions tonight after going through each one tonight.
DarkVenture's Avatar DarkVenture 12:44 PM 02-12-2013
You just need to probe the 9 and 11 pin connectors, the little ones are less important.
frantzray's Avatar frantzray 08:09 PM 02-12-2013
Ok, I am not sure about this short to ground idea. I am getting the following readings with all circuit boards connected except the main power cord connected to the wall.

9-pin results after testing each pin for resistance to ground.

11-pin results after testing each pin for resistance to ground. *Note: this actual pic shows the connector removed so you can visually see what each pin is labeled as.

Also with everything physically disconnected from the Y-sustain except the 9-pin that goes from the power supply to the sustain board itself. I am getting this shut down behavior. Thinking I got hosed on the replacement Y-sustain board.
DarkVenture's Avatar DarkVenture 08:24 PM 02-12-2013
So the primary side of the Y sus is OK but you may have a shorted Y Buffer or the secondary side of the y-sustain (which is more difficult for someone inexperienced to measure) might have a short. What I would do next is a very careful visual inspection of the Y-Buffer chips, there are going to be around 8-12 of them on the left hand side. What I would do is shine a light on the casing and check for holes.

You could also disconnect one of the Y-Buffer boards at a time and see if the set fires up with half the picture missing. If it turns on it works, just turn it off immediately and replace that buffer board. Don't allow the set to run with only one buffer board as this can cause the remaining good one to blow after about 30 seconds (never mind how I know).

You can also check the fuses on the y-sustain by doing a resistance check. Just look for any component labeled with F followed by a number. They can be very tiny or large and are typically placed near power connectors.I think I see one in your first picture hiding underneath the aluminum heat sink.
frantzray's Avatar frantzray 08:45 PM 02-12-2013
I am really confused by your previous statement. There are 8 chips along the left side, but I am not sure they are Y buffer chips. I think it is all one piece.

Here is a better pic of the entire Y-sustain.

Or do you mean the two chips (XRLBT and XRRBT) on the bottom of this pic? If so, they appear to be daisy chained in the middle by a similar 4 wire connector that is found when going from the actual Y-sustain to the XRLBT chip (two grounds and two Va). Also, these (XRLBT and XRRBT) chips have six ribbon style connectors on the bottom of each chip that I am assuming goes to the screen and one connecter that goes directly to the main logic board via a ribbon style cable. Also FYI, I just unburied the (XRLBT and XRRBT) chips today. In all of my past troubleshooting the ribbons and 4-pin cable between the two bottom chips have never been completely disconnected while trying to power on the tv.

“It’s dead, Jim!”

I searched and found this thread. Therefore, I opened up this Vizio VP322 TV, located the power supply board, and saw five caps bulged on their tops.

I purchased a capacitor replacement kit from LCDalternatives. The kit comes with 9 caps. I replaced all 9 caps, bulged or not, leaking or not (I did not have any visible leakage).

The VP322 has been working once again for the past two weeks now!



Update:  It is March 2013.   All is well, as far as the PS fix!   Thanks to all who posted the fix with this model!


I have this other issue on pinks and greens showing up in the brightest parts of an image with  B&W programs.  This has been there before the PS gave up.  


I will search the forum, and if need be, post about this 'color' problem.   It goes away upon reset of the Menu items.   But, it comes back over time. mad.gif

Good Day all; old thread but seems some what active; I have sorta the same issue*

I got the VP422 42" from a family member; they said they were watching a movie and it just stopped working.

First thing i did was check fuses; the main fuse by the input was good; but there in the center towards the top the T4amp 250v fuse was blown. I've replaced it and applied power (plugged it in) there are 2 clicking sounds come from the PS unit when it gets power; the visio light is Orange; no reaction or clicking when i press the power button. One green LED on sub-board off the PS board.

I can't find an exact match where someone had similar problem I'm still TS the issue with multimeter to insure the PS is the issue or not before i waste money. Caps are all good; no bulges. Rev of the PS board is 1.1

So far this is my Power outputs.

AC_Det = 5 v
Lamp (top one w/ orange wire) =.4v
5vsb = 5.2v

No other power.. no power at all when you press the Power button from the PS_on.. no power output from either side vS or anything. All other fuses good. Only that center one was blown (Which I've replaced and has not blown again. Does this sound like a problem PS board or Main board> ?

Nope. I did find the tech manual online. Still need to follow the step-by-step trouble shooting guide to check each pin.

My vizio vp322 finally died after doing the 1 minute startup on off on off sequence for a few weeks. I have a few capacitors on the power board bulging and leaking, will be able to order/replace them after reading this thread.

There are also two more "thingies" that are halfway broken off on the left side buffer logic/ scan board. They are the (2) 84hk 33 100v thingies in the C21 / C22 spots on the board. Not sure if I broke them taking off the back cover or what.

What are they called? Not sure how to find them online to order them, or should i just order a new board?

My Vizio started acting up about two years ago. In Feb 2012 I finally gave up and put in under my bed for about a year. I took it out and let my friend borrow it. Last night it finally crapped out for good. So looking for a local TV repair shop I ran across this forum.
So I cracked it open and there were two leaky caps.

Two 3300uf capacitors, a few burns, and a few curse words later and it's working like new. Thank you so much.

For the first timers I hope this helps.

Used: soldering tool, electric solder wire, and I replaced the two 3300uf caps that were warped and leaking.
swaggerstick's Avatar swaggerstick 05:39 PM 09-25-2013

I had to change the 2 3300 mfd caps and the 1000 mfd cap. it fixed the problem....... i too had 5 screws left over......not bad for over 50 some screws to take out. The repair cost me about 8 dollars plus some time.

Well after reading all the post I didn't find anyone tha my had the same problem that I am having.My problem is that I have no Audio everything else is fine. I replace the caps that you guys talk about and I even replace the audio board and still same problem..Hope someone can help me fix my problem..please

Hello. So I had the typical bad capacitors in my Vizio VP322. I replaced all the caps and the TV worked for 3 weeks and suddenly died. I opened it up and the (2) 3300uf capacitors that I replaced are bulged. All other caps look fine. These 2 are green Sanyo caps which are a different brand than the others. I am wondering if sonething else caused these 2 caps to go or if they are a bad brand. I have not seen any posts where the problem re-occurred after replacing all 7 caps.

any suggeestion what to do before replacing these 2 caps?
swaggerstick's Avatar swaggerstick 12:28 PM 10-07-2013

Were they 10 Volt caps?......The voltage is just as important as the mfd. size. More than 10 volts should be ok but not less than 10 volts. As I recall the 1000 mfd. cap was rated at 25 volt. One other question that I gave is. Did you make sure that the orientation was right when u soldered them in. I am no expert but I do have some electronic experience. Good Luck.........hope this helps.

My VP322 wouldn't power on at all. Opened her up and found a couple capacitors that were bubbled. Ordered replacement "kit" of capacitors off ebay for $11.99, and they arrived 2 days later. Got out the soldering iron and replaced all 8 capacitors that came in the kit (thankfully nobody will see my solder job). Put it all back together, and TV works great!

Thank you all for such an informative thread. You helped me fix this thing for $12 and an hour or so of my time. Thank you!

Really need help. The TV indicator light was only thing working I opened it up found a few bad caps and I replaced. Turned it back on and it did the same issue still. I checked all the solders I did and tried again and now the indicator light doesn't even work. If I can get a pic of the back of the power supply unit maybe I can check that its all proper idk what else to do.
