- www.TheTubeRevi... How to repair ViewSonic LCD monitor with bad power supply capacitors (bubbled out). Symptom is a "blinking" green power button and no display.
It's been a while since i fixed my monitor using this guide, i wanted to come back here to say "THANK YOU REALLY MUCH", i fixed it for 2 bucks, after replacing the capacitors it worked perfectly until now, i sold it to a friend and the monitor is still working great, now i know what to do if my new one ever get this symptoms.Thanks again =)
Many thanks - replaced all six capacitors on my VX922 monitor and it's now working fine. It was a bit difficult to separate the plastic casing - you need to lever the casing outwards to release the catches - and there about three each side. And reconnecting in the circuit board needed some manhandling to line up the plug. So patience, care, and a bit of force is needed! Thanks again for posting the video!
Fantastic. My monitor is now working.
All 6 Capacitors were blown. Most of the damage was underneath when you took them out. Went to Jaycar(Australia) and bought Capacitors, soldering iron and solder for $31.12
For mine VX922, it required
X1 10v 470HF
X3 25v 470HF
X2 10V 1000HF
As per video. push out pins with hot iron. Pushed new ones back in while heating blocked hole. Did not need really need to add more solder.
Interestingly the monitor does appear brighter.
thanks again

Yet another satisfied customer. I have had my "broken" VX924 sitting in my office for about 2-3 years now. I just could not bring myself to trash it. I just soldered on 2 new caps and it works. Unfortunately, I don't need the monitor any more. I suppose selling it is much better than trashing it though!
I repaired yesterday my VX924 with this exact same problem. My power supply have only 4 big capacitors. Three of them looked suspicious and i replaced them. It cost me € 1,35 for the parts from a local store.
Thank you for this video witch i accidentally found but now i am happy and i hope i doubled the lifetime of this nice monitor. (y)
Confirmed that this works for VX922. Replaced all 5 capacitors in the row shown in the video (all next to each other on one corner), and the one in the center of the board. The smallest cap on the board wasn't bulging up, so I did not replace it. I used:
(4) 470uF 35V 105 degree caps
(2) 1000uF 35V 105 degree caps
The 1000uF caps I used were slightly larger in diameter. They were rated to take higher voltage than stock 10V caps. Thanks for this video, the fix saved my favorite monitor!
I have a ViewSonic VX922 that had this problem. Your video put me on the right track. I replaced a 470uF and two 1000uF capacitors that were all bulging up. Fixed me right up for $5 in parts. Thank you for the video help!
You sir, are an absolute legend!
My VX912 started doing the blinking thing. Whipped it open, took the two bulging capacitors out, popped round to Maplins(UK) but they only had one 470μf25v in store. So I bought two 1000μf25v ones at the hugely satisfying cost of £0.84 ($1.29), popped them in and switched it on, no more blinking!
And all in less than an hour, Fantabulous!!!
I repaired my VX922 (mfg 2006) thanks to this video and some of the other peoples comments.
Old Caps
1x 470uF 10v 105c
2 x 1000 uF 10v 105c
3 x 470uF 25v 105c
New Caps
Old Caps
1x 470uF 16v 105c
2 x 1000 uF 16v 105c
3 x 470uF 35v 105c
Since I'm not sure what caused the original caps to fail I bumped up the voltage on them.
Some notes:
- I was careful removing the back cover but still broke parts of the plastic holding clips. 1 on each side.
- Used solder wick/braid to remove old solder.
Fixed my $200 monitor FOR $1.93!!!!!!! Omg. :D After disassembling my Sceptre monitor I found just 1 bulging capacitor! Went to radioshack and got matching capacitor, little solder and POW! working like a charm. Been w/o this thing for 3 months,
Hey, I want to thank you for the video post. I have a VX922 and was having the green blinking light of death. I popped the case and all but the 400v cap were showing signs of bad bloating. I replaced just the 470 caps as they were the only ones available and my 5 yr old monitor is no longer dead. THANK YOU SO MUCH!! Not only have you given my monitor a new lease on life, but now I have purchased the gear for a home business. THANK YOU! :)
Thanks for this, I had a VX922 that was dead and a VX924 that was giving me migraines with the shimmering diaplay....took both apart today, quick run to the electronics store, back home and a couple of hours later I have 2 perfectly functioning monitors! Welcome back dual screens and goodbye to migraines!
Great tip! I just managed to fix my Viewsonic VX922 monitor by replacing 5 capacitors (3 X 470μF/25V and 2 X 1000μF/10V) - Παίδες το tip δουλεύει!!!
I had the same problem with a vx922 (not a vx924 like this video) and i replaced the 470 μf + 25 volts capacitor with a 1000μf + 25 volts capacitor and i followed these steps and it now works perfectly. And i only changed one capacitor, the one that seemed more suspicious
Good job mate, cheers and thank you for your effort making this video, it really helped a lot of us
I recently repaired my Viewsonic VX922 using this great video tutorial. I had 7 blown capacitors, easily distinguished by the rounded domes on each bad capacitor. As I unsoldered each capacitor I kept track of the type (example: 1000 uF 10V) and the location (example: C244) on the circuit board by writing them down on a sheet of paper. The board clearly marks the negative and positive for each capacitor. I ordered the capacitors on eBay, other types were: 470 uF 25V, 470 uF 10V. Hope this helps.
Just did this and have saved my two vx922's. You are my savior.
thank you, i just fixed my monitor, even though i have no idea of electronics, your tutorial is very easy to follow
i only changed some transistors i got from a local electronics store
thanks!
This worked perfectly! I was going to go buy a new one, but took a minute to look it up on the internet and boom there was your vid. Took me about an hour, this was my first capacitor replacement and now I want to fix everything. I had no problems and was stoked when it fired up on the first attempt. Thank you!
Thanks for this video!! I was probably going to throw my old VX922 out, but after watching this video, I disassembled mine and found 3 bad caps. Tomorrow, I'm going to buy an iron, some solder and find some place local to replace those bad capacitors. Full of confidence now!
Great vid! I have my power supply board in front of me right now, and there's three capacitors that are obviously bad on my ViewSonic VX922: 470 micro-Farad 25V, 1000 micro-Farad 10V, and another 1000 micro-Farad 10V. There's a smaller one labeled 470 micro-Farad 10V that looks "domed" as well, so I'm going to replace all four. If I don't post again, it's because it worked. Thanks in advance!
Fantastic. Thanks for these instructions. Fixed my VX912 - the repair - two capacitors - cost just 92p
Thanx dude, i just fixed my vx922 thanks to you. It was pretty hard, to plug back the power supply board onto the the logic one, but it was worth it, is working now. Thanks again.
after thinking it was an OS problem not being able to wake up just this monitor in my newly installed multi monitor setup, i searched and found this. I took my VX922 apart and sure enough, like everyone else, i have the same problem in the video. Thanks.
I'm going to replace the caps in mine too. I have great fix-it skills but with only rudimentary electrical knowledge. I'm going to ask friends to see which values I can change and still be compatible to possibly make this more robust.
Great Video, had to replace 2 * 1000uf 10v capacitors and monitor works like new. Took only 30 minutes. Absolute champ. Cheers
My VX922 is doing the same thing, but intermittent. I'll make a trip to the local electornics store and pick up some caps.
Thanks for sharing this video..
@kryptiea Great question! They all have small numbers on the side, and these will vary between models. The "bad" capacitors will have a round "hump" or "dome" on the metal end. Read the numbers on the side of these parts and buy your replacements to match. The numbers are values for "capacitance" (uF) and Voltage rating (V). Also make sure you are getting a PC board capacitors (Both wires come out the same end) hope this helps, Good Luck !!
@punfs I didnt see him put the little hex bolts back in that hold the external video and power connectors solid in the cover-- these not only provide a place to thread the video connector thumbscrews into, they also keep the connector leads on the board from being dislocated when plugging the cables in and out. Maybe I just couldnt see it in the video-- either way, I just did this on my VA912b viewsonic and now its up and running like new again - helpful video! thanks, Mike
@punfs I never guessed so many people would take advantage of this. I am really gald I took the time to put this Up! I had just got my FlipVideo camera and wanted to try a quick production. The whole video took me about 2 hours start to finish. Thanks for atking the time to pass your results along. The more people who do this will motivate others. It really is pretty easy, even if you aren't that handy or whatever.. Thanks again!
@lite1979 Just as a follow-up: I borrowed a soldering iron from a friend, bought some solder and some copper braided wick just in case (to soak up extra solder). I was able to remove all of the bad capacitors by heating them up - got a little messy and got kind of close to some other solder points, but didn't melt them. I'm posting this from the fixed monitor right now. I used a nail clipper to clip the long ends off the new capacitors. Ebay is a good place to find the capacitors. $13 total
@132aris I had this same type of action on another VX924. Try replacing the other capacitors on the power board. This worked for me.
Thanks for the video, after seeing this I replaced the capacitors on my VX922, and it's now fixed!
Thanks my friend.
It works.
I have a View Sonic VX922 and i changed 6 capacitors and the green light stop blinking.
..And works fine!
Hey, I had the exact problem with my ViewSonic VX922 and found your video here quite some time ago. I findally managed to find the time (and courage) to repair this electronic device (first time smoldering for me) and it worked out perfect. The monitor is working like new. I replaced all capacitors on it, they were all bad imo. Thanks a lot for uploading this helpful guide, if it wasn't for you my monitor would have landed in the garbage can. :D
Thanks for the video. My VX924 had resolution problem which it won't go below 1024x768. Now it works like when I got it.
Thank you!!! I'm the "software" kind of guy, not really the "hardware" kind, much less if it means messing with capacitors (in fact, before this video, the only time I heard about a capacitor was in "Back To The Future"). Anyway, since I thought I had to buy a new monitor I figured "what the hell, I'll give it a try". To my surprise not only was I able to do everything instructed, but it actually WORKED!! All for only $2.78 + tax!! Well, + another $7.99 for the soldering kit I get to keep ;-)
thank mate working again changed two capacitors,all for two dollars great vid.
@Silverhorn2k5 Awesome! This is the power of information. What was set to go to a landfill is now working again!
Thanks for this. I've just repaired my VX922 by replacing two bulging capacitors.
Glad I found this video, VX922 here, thanks!
Thanks so much for the response. Note at 3:24 the bad capacitors will have a "domed" shaped swelling on the top from the pressure inside. Note the value and the voltage rating on the side and simply go to ebay search. In my case i needed 2 pieces 1000uf at 16 volts. ebay ID dementg sells these very cheap. I paid $5.49 total to fix a $125.00 monitor !!
Thank you, got my VX922 working again with your instructions. :)
@BatistaReel Glad to see you were not afraid to touch the Flux Capacitor. "10,000 Gigawatts, Ben what wa i thinking?" I am glad to see you left your comfort zone to save some bucks. This stuff can get addictive!
@getonthetubedude Hey thanks - Just replaced all the smaller power supply caps on my Viewsonic VA912b and it works like brand new-!! Five of seven caps were showing bulges, so just replaced all but the huge one that im told never fails. Used hi temp caps from parts express and couldnt be more pleased I didint have to buy another monitor - thanks, Mike
Thanks so much for your video! I was able to order the capacitors I needed for my Viewsonic and fixed it in about an hour.
Man, MANY THANKS!!! You save my old ViewSonic VX922 (75hz, 2ms, my favourite for gaming) :D
Yeah, i'm so happy, thank you mate!!
thanks!!!!!! i can fix my vx922, excelent tutorial!!!!! thanks again!!!
george from the end fo the world (argentina)
Worked. Didn't take long. 6 of the 10 or so capacitors were bad.
FANTASTIC! Thanks for the help. Did what you said, and it now works great!
@ASUSproz One thing to double check,,, Did you make sure the polarity marks went into the correct hole for each capacitor? They usually mark the minus (-) side of each little can. Other than that, I would check for solder bridges (drops of solder that accidentally are shorting the connections) or loose solder joints.
Thnx a lot buddy! Worked like charm.
Got my VX922 working again . :)
Yes this same problem exists in flat TV's, also in computers, theres even a class action lawsuit against either dell or gateway due to mass early PC failures--
I know of a 50" Plasma that needed four caps replaced and it did the trick, works like new.
Most likely the same problem. Take a close look at the capacitors (little cans) sticking up from the power supply board. If the have a hump or dome shape on the top, they are bad. Read the numbers along the side of the capacitor and do a google search to find a supplier. eBay will have them for sure. Hope this helps.
Just wanted to chime in and say thanks. I have had two ViewSonics (they are both Q20wb models) for a while. One has had this problem for a year or two and I just never investigated the problem-it sat around gathering dust. Yesterday, the other (my main monitor) just stopped working and its power light is now a very dim yellow. I have no idea what the problem is, but I'm going to try swapping out the "recently broke" power supply into the "ago broke" one to see if the green light prob goes away.
@koopa8585 Sometimes they do not show any physical bulging. Yes, I would give it a shot for the few bucks more it's worth a test!
This same methods works on Dell, Hitachi, Sony and just about any brand LCD. The key is finding the power supply board inside. This is where the BAD capacitors will most always be found.
@yambo59 i know mate, good job and enjoy your new monitor (again) :) its a satisfying feeling having a "new" monitor with just 50 cents (or less)
AWESOME I have a viewsonic VA1703wb came on for 2 sec then nothing.Keep in mind I have never done anything with eletronics in my life beside hit power button I watched a few vids on here borrowed a soldering gun 4 dollars in caps and 3 hours later[anyone who knows what they are doing prob half hour 45 min]like BRAND NEW.The first thing I have ever done correct woohoo
@cozykris Hard to say exactly. It's always easier when you can see something physical wrong on the board. It's a little like being a detective! What doesn't look exactly right? Are there any parts that look burnt? Or look like they have been extremely hot? There is still a good chance it's on this board.. Hope this helps!
@fleetwoodsucks Could possibly be the culprit here as well. Look for any signs of heat or phisical damage. For everyone, I know most of you know this , but just to be sure, always kill the juice on the equipment before working!
Am doing this repair right now... I have a VX924... my 100uf 400V one is blown as well so yeah... I need to get a few more... also these are the ones I had in my unit... x2 470uf 25V | x1 330uf 25V | x1 330 35V | and the big dog... 100uf 400V ... ofcourse if this fails you can still get this entire board bit for $33 your choice if you do not have a sodder iron
Thanks for the video, helped me fix mine ViewSonic as well, easy solution...
Awesome tutorial. But I have a question. Is it possible to take capacitors from let's say, a mother board and put them into a monitor? Or how about a spare Imac capacitors for it's monitor and place them into my monitor that I'm planning to repair?
To clarify its a LCD viewsonic N3250w, January 2006.
Where can I buy these capacitors? I have a Viewsonic VX924 that did the same thing so I just bought a new monitor, but since I found this, I'd like to get that thing up and running again.
Thanks for the video!
Hello there. Thanks for that video. It helped me fix a ViewSonic VX724 which was almost the same as the one on your video. There was no image and a friend of mine was to throw it to garbage. Cost me around 5 dollars of capacitors and tada... and about an hour work. The only thing is that once in a while, it blinks. There is like a camera flash in the center of the screen, but it keeps on working well. What would you think is the problem? Thanks for answering.
@garagecrap you are partially right, theres two reason these fail, first is low grade caps, second is too close to a heat source as you mentioned. the heat sink bakes the electrolyte and shortens the life. I used hi temp caps for this reason - I just did this repair, and noticed there was plenty of room on the board to put these caps elsewhere, but they want us to buy more monitors and you can guess the rest-lol crooks --
hello thanks for this instructional video i have a viewsonic vx922 i have followed all the steps now am on the step that you have to identify the bad capacitors but it seems like all my capacitors are domed up apart from the tiny one that is next to the cylinder like battery thing i dont know what its called haha. so i dont know if i have to change most of them ?
please help thank :)
@punfs No kidding, I know a guy in Arizona who's started taking monitors in for repair to make a few $, & hes flooded with work -- easliy 2/3 of the ones he fixes have this same issues. Indidentally the monitor I fixed a month ago is still working fine. Oddly enough, I have CRT televisions that are almost 20 years old and have never needed the caps or anything else replaced -- tells me the quality and location of the caps in these new monitors and TV's with this problem are suspect
thank you for your videos. The problem is i have replaced the capacitors in the power supply of a Samsung monitor (Power Board IP-35135B). I even replaced the ones that looked fine in case they couldn't hold up charge anymore. Still no success. Back light still doesn't lightup. I know for a fact its the power supply problem because i have tried it with a different known working one and the monitor lights up.
Do you have any solution? Could it be other problems such as transistors or coils?
Wow and here I was thinking it was my video card. I have the same monitor, I'll have to try this. It's starting to get real bad now about not showing anything on startup.
Glad it worked!! $2 < $145 for new monitor right?
Good repair.. I got analog working again but the DVI seems to not be responding... oh well analog with a dvi adapter is fine with me....
hi there.great video...I have a strange problem. I have a viewsonic va1916w.When I turn it on it does work normally for 3 maybe 5 minutes and after the screen goes off but the indicating light stays on. I turn off and then on again the monitor with the power on button and then it turns on again and after that it does the same thing. I replaced a damaged capacitor but it didn;t solve the problem. Could you give me any idea of how to solve this. Thank you in advance.
i get the blinking green replace capacitor no more blinking but black screen no signal
i have an old crt that has this problem of the power light flashing, Do you think it would be a similar fix? Should i open it up and look for domed capacitors? near where the power comes in?
hi there!!! i need your help..i had a monitor problem but it is a viewsonic VE710s. i cant see where the screws are..i want to open the back of the monitor to see if theres a capacitor bulging cause my screen display is so very dark and hard to see.i change every settings for the picture but still not working..hope you could help me..thanks!!!godbless u!
Muchas gracias, me gustaria una pagina en español
I replaces 2 bulging capacitors on a viewsonic vx910 however i still have the blinking green light . should i replace the other capacitors? or could there b
e another problem?
How do you know what capacitors to use and where to get them? Are they all pretty much the same from monitor to monitor?
Hi um I have a 37 inch LCD ViewSonic um and it's having move is she shut off would keep on going and going will stay on some day some days it won't and I'll go grab the pointing light and its won't turn on at all some days um leave a message please on the bottom there and would be nice if I could have small I can't find the capacitors for so I'm wondering if there's anything compatible with it
Hello video uploader, i have a question for you. I have the same vx924 as you, have had it since it came out ( many years now). I've noticed a buzzing sound in the back of it and after the monitor has been on sleep for the night and I move my mouse around to wake the computer up it goes in and out of picture for 2 or 3 minutes and then it will be working as intended. I don't think anything is wrong with the cable as the monitor will work. My feeling is that it is a bad capacitor?????? thanks
would that mabye be the problem of my advent lm1704b i opened it and it has 1 doomed capactior ?
Hey man I have the same problem. Im getting a soldering gun soon and im gunna repair this baby by myself (since warranty is void).
Can you tell me, what type of power capacitor do I need? Is their a certain brand/model? Should I order it from viewsonic or a manufacturers website? Or can I salvage one off another monitor?
i replace the capacitor with the exact numbers but different name band still getting the orange light does the band have anything to do with it
hello
I need the integrated reference U101 that burned this VX922 monitor. thanks
my green powerbutton does the flashingthing, but only when it goes into native resolution on the DVI-connector, the VGA still works fine, is it still bad capacitors then?
Hi here !
I fix my screen a year ago with this.
But recently, it does the same thing. I disassemble it, but... all capacitors are fine !
Any idea ?
would it be okay to use 85 degree caps instead of the 105?
@handyman6042 Mark sure the + marks go in the correct hole. Could also be another problem as well. Sorry not sure!
Thanks for making this
hey i have a vx2450wm-led and it will flash the viewsonic logo then immediately power off and keep repeating the process please help if you can
Hi there, I have the same problem but nothing change after caps replace, they was like new, no blow but I change 4 of them for brand new, and still green led blinking :( Any ideas ?
1 x 470uF 50v
1x 220uF 63v
1 x 330uF 35v
1x 470uF 25v
Which capacitors should i buy? i mean the specs of all of them.
hmm. I would like to ask if anyone knows the value of the fuse in power supply in amps.
I need the value of diode zener zd121 . Might I tell me ?
Cool, thanks.
FOLLOW INSTRUCTIONS AND THIS WILL WORK WONDERS!
@cozykris Could be something else wrong. Any other parts look damaged, too hot, "melted" ? Play detective, you may see a clue!
Hey I have a problem with my tv/monitor its a viewsonic N3250w and I've had it for about 8 in a half years yes I know it's old but just recently like today and yesterday but now it won't turn on at all but anyways so I've tried pressing the power button several times on tv and remote I've unplugged it and plugged it in and tried other outlets to rule out a power issue but for sure inside the tv so it won't turn on at all now. And I tried connecting my PC to the tv because it can and has a long time ago been used as a monitor and I did that so if it were connected I wouldent have to turn it off and back so that it would just go in sleep mode with the PC. Because I got it to work yesterday and once I turn it on I can turn it off and back on but after like an hour it won't turn back on period so hopefully this is enough of information for someone to help me out if you can help plz do would be so much appreciated, thanks.
that problem my LCD viewsonic VG1921 19 help me ..problem
