I got the same monitor from a friend for free. I've used it for a couple years but yesterday mine had the same problem. Ive never attempted to replace a cap or mosfet before but here we go. Thanks for the detailed video! I helps me feel like I can continue with confidence as I attempt the repair. Cheers
Yes, the problem was that, at one time, Nichicon had a defective batch of the HM and HN series caps that caused them to leak prematurely. A notable amount of Dell and other systems were affected with them. I can't remember exactly when they fixed the problem. Nichicon are normally good caps, and I use them in my repairs.
Great video tutorial. I have exactly the same monitor and same problem, but the capacitors look fine. I opted instead to remove the inverter board and the CCFL tubes and replace them with an LED array. Cost me about $ 44 CDN including shipping for 360 leds on 1 meter rolls.
I had the same as described intially in the video. Having test all the compnentry around the board you described, I found no bad caps or mosfets, or inductors etc. Having had experience with these types of issues I suspected something else if they used cheaper caps for that board. So, I just performed a resolder mod on th esame board you changed the parts on. This was successful as well. My experience tells me that this board might have faulty solder used.
Thanks for the video. I replaced the capacitors with Suncon capacitors and the monitor works every time i switch it on. I had the problem where i'd lose the screen if i turned it off and couldnt get a picture again when switching it on. The Acer logo would go on for a second or two and then disappear with no picture! Couldn't have done it without your video, thank you :-)
Excellent video and tutorial! I would have liked some vid footage of you removing parts and soldering, was hoping to attempt this myself BUT ONLY because having never soldered anything before in my life...(LOL).. I'll be pussing out :D and passing this off to repair guy locally but giving him the link to this video. Thanks again!
Great video Maxx my al2416w has just died, I bought a new 27" but will have a go repairing the acer because will make a great spare if I can get it to work, thanks dude.
@Maxxarcade It looks like the one I'm looking at. That mosfet is Q6, and then the caps, from the right, are C38, C36, C35, C34, C39, C3, C2 and C1. Those are just those caps lined up.
That's a cool idea. I wish all LCD's had the lights behind the screen instead of at the edges. Most of the edge-lit ones are too small to fit LED strips into.
The only way to know for sure is with an ESR meter. I use a CapAnalyzer 88A Series II. It's been a while since I did this. but I think the caps I used on the inverter were United Chemicon KMG series. They were the only ones I had available that were the proper diameter and value. The monitor is still working well today though.
Those are great for just about anything. Only circuit that they might not be ideal for is the CPU VRM output circuit on newer motherboards. The newest VRM I've used them for is Socket A and Pentium 4 stuff.
@TromboneSexy There are too many bad ones to list. Some of the more common crappy ones are Teapo, G-Luxon, SamWha, Fuhjyyu, Lelon, Gloria, etc. Good ones are Nichicon, United Chemi-Con, Panasonic, Cornell-Dubiler, Rubycon, and possibly some others. Mainly the ones from Japan and USA. Though there have been a couple defective ones from good brands before. Nichicon HM and HN series had a bad batch a few years ago, and so did Chemi-Con KZG. These were used on computer motherboards.
I was hoping to edit my previous comment. I used Turnigy High Density R C LED from Hobby King The Acer AL2416W uses 6 U shaped CCFLs that span the full width of the light box. The CCFLs seem to get diffused better than the new LEDs that I installed. In hindsight it would be better to install 14 to 16 rows of LEDs instead of the 12 rows I used.
@Aussie50 Samsungs are notorious for bad caps. Let me know what you find! Usually the standby light is orange. If it is blue and there is no picture, maybe the backlight is out. That will be a sweet monitor to fix though. 24" ones aren't cheap, even used.
@Maxxarcade I couldn't find a obviously blown cap in it so I have a full set on order to recap the whole PSU. I did fix the 32" Proton HD LCD tho, but its still got a bit of picture noise (dvd looks like VHS quality) and again, I think the PSU needs a full recap. the 2 1800uf 35V ones look a bit old and sad.
@GriefEriksson You need to replace all the caps on the inverter, and check for shorted mosfets. Does your picture appear for a second and go out, like this one did?
Wow! I was so surprised to see so many step up transformers on that power board! what was there like 11 of them or so? I''ve repaired a few monitors too and usually they have like 2 or so, one for each CFL behind the LCD,one up top and the other on the bottom. so I have to ask, how many lamps does that board power?! its a beast!
I have the same problem. I removed the components, and so far, so good. Waiting for the replacements to arrive. However, since I have never worked with surface mount before, how would one mount the transistor? I have a Weller WTPC with a TC201. Thank you.
I have years of experience doing cell phone repairs, and light soldering, and circuit board cleaning and repair. Not looking to set up shop on this one. Just a 1x repair for personal monitor. I don't have an ESR meter, nor spare inventory of caps. Any cost effective advice? Where is the best place to order a handful of Caps at a good price? What are the good brands that are reliable? Any additional tips or advice for a rookie on ordering the correct type and style of caps?
Amazing I had the same issue and just ordered a replacement inverter board :) hopfully it will work well :) if it does I will probably have to buy a new graphics card as I just bought two new monitors to replace it and my current card only supports 2 monitors.:S
Thanks for the vid. I opened up my dead AL2416W up to find those same 4 capacitors shot. One was burst right open, and the others were swollen beyond belief. There was no visual evidence that the mosfets had shorted out on mine. I bought replacement 100uF 35V caps, and had a tech install them for me, but the monitor is still dead. I have no expertise in electronics, if the mosfets looked fine, then is there any reason to believe I should replace them as well?
Thanks for posting this. You may have already answered this in your comments, but here it goes... I had the same problem, but the ACER logo didn't show up. I replaced the bad capacitors and now I get the ACER logo for a split second. The MOSFETS didn't look bad, but do you think they could be? I'm just a "tinkerer" with no real training. Let me know your thoughts! Thanks
Maxxarcade Do you know the Mouser number? The ones on the board are P2804BDG, P5504EDG, 17812. Those numbers don't pop up on the Mouser website. Thanks for your help. Mouser is great BTW!
incompresistible Hmm, going by memory, I think these are what you need. P5504EDG = 512-FDD4685 (I think this is the one that was shorted on mine) P2804BDG = 512-FDD8451
my monitor IH252HPB has been having a specific issue: The monitor comes on then will sleep mode. I try to move the mouse as normal, and the screen wakes up for a very brief moment, so that I can see my desktop for a short period of time. Then the screen instantly goes to sleep again. Occasionally, I can fix this problem by pressing the power button on my monitor a few times. Most of the time though, I have to do this process many dozens of times before the monitor reveals my screen.
Thanks. My LCD monitor got a burning smell and later not functioning perhaps of overusage, is the capacitor or the inverter the part(s) to be replaced?
Thanks, same monitor, same problem. replaced the capacitors and the 2 mosfet and the monitor is working again. I would like to know the proper way to unsolder the mosfets. about $10 in parts.
i gotta change the caps in a old computer of mine a cheap compaq from 2007/2008 they failed pretty quickly since about 2/3 years ago it started failing
I have an Acer X233h 23" LCD Monitor. Its started having a prob with a 3" vertical bar that was dim with a single pixel width red line vertically within the bar. then after a few months just went totally black, wont power up. I dissembled it and inspected the boards, and there are no obviously bad caps. the only thin that looks odd is a water-mark type lines around the board mounting) boards look 2 be in new condition otherwise. Would you still recommend replacing all the caps on both cards?
Hi.I have the exact same monitor, with the exact same problem. Would you be willing to give me some more details on exactly what you did? I dont know a thing about electronics, I dont know what a capacitor or inverter or ESR meter, or any of that stuff is... do you think theres any chance I could fix this ?
Hi, I have the same monitor bought it new in 2007 hardly ever use it was sitting here tonight and it started coming on on its own.Think its a cap problem?Thanks
Hey Maxxarcade, I have a samsung monitor that is bad. Slowly died, flickering. Any suggestions on getting it fixed? Its a 2006-2007, debating about shipping it to samsung for a $150 repair, but looking for a cheaper option. Thanks in advance!
Mine had the flickering but as long as i didnt turned it off it would work alright, it will go to sleep and everything without any problem. It also started smelling rly burnt just yesterday, I'm going to take it apart and see what began failing. Have you resolved your burning smell issue? Thanks.
what did you studied? i wanted to go for TIC'S but in the end i decided industrial ING im into the electronical stuff, thoug industries here have a bigger part :/
Hey, I got the monitor, and some reason, it powers on, but it is just a blank black screen. the capacitors and parts look well and sometimes works, but sometimes it doesn't. any thoughts?
Nice vid frm the past i have same mon and its just started stopping so ill be referencing your vid when its fully stopped :-) There a great mon otherwise, i like 16:10 like you
I saw you play minecraft!!! I Saw you!!!... By the way, I have 2 of that model but without the DVI part...Logo appear about 0.5 seconds and then nothingness...How to repair this?
Type in sawder into google it's not there, Solder is. You may find soft sawder, which has a different meaning. I live in Europe and have been to almost every country in Europe some more than once (Spain 5 times) on motorcycles, holidays etc. Dickbreath.

Buenas tardes.
Seguí paso a paso tu video y pude hacer encender mi monitor acer.
Muchísimas gracias.
Saludos desde México.
Unbelievably, I've had this very same Acer monitor since Oct of '07 and I like it a lot. Fortunately I haven't had any trouble with mine...
Great video tutorial. I have exactly the same monitor and same problem, but the capacitors look fine. I opted instead to remove the inverter board and the CCFL tubes and replace them with an LED array. Cost me about $ 44 CDN including shipping for 360 leds on 1 meter rolls.
Very nice repair and you can't beat the price!!! Love your videos.
Very nice walkthrough. I have the same monitor and I'm thinking of doing the same repair. Thanks for sharing.
great repair!. I've got a samsung 24" doing similar. blue standby light stays on, no startup. I'll have another look at is soon.
I had the same as described intially in the video. Having test all the compnentry around the board you described, I found no bad caps or mosfets, or inductors etc. Having had experience with these types of issues I suspected something else if they used cheaper caps for that board. So, I just performed a resolder mod on th esame board you changed the parts on. This was successful as well. My experience tells me that this board might have faulty solder used.
I'm gonna try this since the parts should be less than $20. Thank you so much for sharing.
It's a 16:10 monitor, hence the 1200 line height. 1920x1080 is 16x9, which is more common these days. I really prefer 16:10 for computers though.
Thanks for the video. I replaced the capacitors with Suncon capacitors and the monitor works every time i switch it on. I had the problem where i'd lose the screen if i turned it off and couldnt get a picture again when switching it on. The Acer logo would go on for a second or two and then disappear with no picture!
Couldn't have done it without your video, thank you :-)
Gotta love that feeling when you first power it up and it works after a faulty part repair! :-) 5:29
Thank you very much from Spain.
Your video has been extremely useful to repair my LCD AL2416W.
Muchísimas gracias.
@octonian Cool, hope you can get it running. These are nice monitors.

@QsoftStudios Usually Mouser Electronics.
@Knaeckebrotsaege Ya, I think I saw that. I need to catch up on stuff over there!
This seems to be better made then the LG.
i just like the videos when you fix stuff.Nice."New" monitor for nothing :)
@karmabike1 I thought about doing that too, but it's pretty cold in my basement, and the monitor gets light use.
@Maxxarcade I couldn't find a obviously blown cap in it so I have a full set on order to recap the whole PSU.
I did fix the 32" Proton HD LCD tho, but its still got a bit of picture noise (dvd looks like VHS quality) and again, I think the PSU needs a full recap. the 2 1800uf 35V ones look a bit old and sad.
You can turn the Antivir nag screen off :) Just involves a bit of bodging in the security section of Administrative Tools.
i had the same thing with my monitor twice. after removing the shield i have had no problems with heat. or caps or ic's.
Nowadays I use Microsoft Security Essentials. I used to use AntiVir.
@GriefEriksson You need to replace all the caps on the inverter, and check for shorted mosfets. Does your picture appear for a second and go out, like this one did?
knowledge is power. most people would have just bought a whole new monitor.
Wow! I was so surprised to see so many step up transformers on that power board! what was there like 11 of them or so?

They should have changed thise caps, they're overloading the mosfet :(, Should be a very easy repair, Good job on that one :)
@csanchez999 That's the meter I use, it's great!

wish i knew someone i could send one of my monitors to. need to have it checked. hopefully fixed.
@bangonitdave Everything is shown in the video... I can't take it back apart to get the exact location numbers.
@Cyantist2 Most of the time it's more than just caps for me, but once in a while I get lucky.
my monitor IH252HPB has been having a specific issue: The monitor comes on then will sleep mode.

It's 1920x1200, but I'm not sure if it has HDCP or not.
what kind of ESR tester do use I was interetsed in buying EDS-88A CAPANALYZER SERIES II ?
what do you think ? I loved the video !
@sasa78016 Have you tried Ebay? I'm not sure if I know any sources that would ship there.
Thanks. My LCD monitor got a burning smell and later not functioning perhaps of overusage, is the capacitor or the inverter the part(s) to be replaced?
MEK will remove flux, but you have to keep it away from the plastics...
Are the capacitor and the inverter the culprit of the burning smell in Acer LCD monitor?
Thanks, same monitor, same problem. replaced the capacitors and the 2 mosfet and the monitor is working again. I would like to know the proper way to unsolder the mosfets.
about $10 in parts.
can you leave the back cover and the metal shields off and run it as is? any side effects to doing that other then lots of dust?
You are such a freakin' pro
when are you going to be looking at that giant dell tv or whatever?
i gotta change the caps in a old computer of mine a cheap compaq from 2007/2008 they failed pretty quickly since about 2/3 years ago it started failing
And the funny thing is, I'm typing these comments from that monitor right now, down in my workshop :-)
What soldeirng/desoldering tool did you used? I dont have a solder gun I'm looking for recommendations. Thanks.
I have the same questions as svenkka1, same problems as in the video, hopefully same solution. What brand of caps did you use to replace the old ones?
I have an Acer X233h 23" LCD Monitor. Its started having a prob with a 3" vertical bar that was dim with a single pixel width red line vertically within the bar. then after a few months just went totally black, wont power up.

Would you still recommend replacing all the caps on both cards?
Should be ok for most of that stuff.
@glenerd1988 No, I was replying to some MUPPET that is learning English, but I replied to you by mistake.
Hi.I have the exact same monitor, with the exact same problem.
Would you be willing to give me some more details on exactly what you did? I dont know a thing about electronics, I dont know what a capacitor or inverter or ESR meter, or any of that stuff is... do you think theres any chance I could fix this ?
I desperately want to see caps in one of your repairs, and I have no clue why.
@sheps999 Yep, I've just been too lazy :-)
Hi, I have the same monitor bought it new in 2007 hardly ever use it was sitting here tonight and it started coming on on its own.Think its a cap problem?Thanks
Could be. Can't say for sure without taking it apart.
Hey Maxxarcade, I have a samsung monitor that is bad. Slowly died, flickering. Any suggestions on getting it fixed? Its a 2006-2007, debating about shipping it to samsung for a $150 repair, but looking for a cheaper option.
Thanks in advance!
How did you get the mosfet of? they seem to be glued down so i pulled some of the pcb off with it
Mine had the flickering but as long as i didnt turned it off it would work alright, it will go to sleep and everything without any problem. It also started smelling rly burnt just yesterday, I'm going to take it apart and see what began failing. Have you resolved your burning smell issue?

@derrickdent37 Mouser Electronics.
@pathman2 That's the way we pronounce it here... The L is silent. Watch some other people's repair videos and you'll hear them say it the same way.
What ESR meter do you use? I am tired of using an ohmeter.
What are the values of components which need to be replaced?
How about high-density yellow Elna capacitors?
Hey, I got the monitor, and some reason, it powers on, but it is just a blank black screen. the capacitors and parts look well and sometimes works, but sometimes it doesn't. any thoughts?
What is the name of the capacitors you replaced on the mainboard?(i can;t read the name :/)
guten tag!
man i gotta send u my widescreen monitor cuz im in need of a repair cuz it doin da same thing its a Westinghouse 19"
Nice vid frm the past i have same mon and its just started stopping so ill be referencing your vid when its fully stopped :-) There a great mon otherwise, i like 16:10 like you
Nice!
TDK electronics generally aren't cheap.
I saw you play minecraft!!! I Saw you!!!...
By the way, I have 2 of that model but without the DVI part...Logo appear about 0.5 seconds and then nothingness...How to repair this?
Are those busted caps CapXon brand?
where did u get the parts i got a AL1916W
Have you had any problems with that monitor? Is it going well? :)
Whare do you get your parts? (MOSFETS, caps etc)
That ought to be a good monitor...it has a Samsung PVA panel.
Nice fix. Cheap Monitor....
Wish in my city people throw that modern stuff away,heh, i find only 15yrs. crap..
nice
A TDK board ?
