Re: Acer AL2416 AL2416W 24" 1920x1280 LCD Monitor
Allright,
I gave one last shot at my original board. Since I was sure the fuse was blown, I replaced it and voila! The monitor is back to life.
So the inverter board from eBay was likely faulty. So the question now is what the right value for the fuse? I saw people saying it was 'W', others were saying 'M'. I got a 'J' surface mount fuse, rated at 1.25A. Not sure how long the new fuse will hold. Crossing fingers.

Re: Acer AL2416 AL2416W 24" 1920x1280 LCD Monitor
I thought about this and tried connecting only one half of the circuit with no luck. I already attempted a repair on the original board, and it lasted about 2 weeks at 8~10 hours/day until it failed again. I didn't investigate the root cause this time; the fuse is blown up again (I actually verified that) but i am unsure about the FETs or the capacitors. I thought it would be easier to just go ahead and get a replacement board altogether, but it looks like even this is a risky business.

The strange thing is that with the old inverter board, with fried components, the picture shows up with the left side of the picture dim. This seems to point to the inverter board not being recognized by the main board or something along these lines. I have requested refund from the eBay seller, but it's going to be an uphill battle....Leave a comment:

Bump?
The problem might best be described as:
Turn on monitor: no picture, no logo
Turn off monitor: Perfect picture for a second, then power light is amber and no picture...Leave a comment:

Re: Acer AL2416 AL2416W 24" 1920x1280 LCD Monitor
To the brains of this forum.
I bought a replacement inverter board, and replaced my old one (which worked for about 2 weeks after repair).
The problem I have now is that there is no picture when I turn the monitor on. Then, when turning off the monitor, I see a perfect picture flashing just before the power light turns amber.
Anyone has a clue on where this could be coming from ? At this point, having spent $60 on this monitor, I would love to see it work again...Leave a comment:

Polarity was respected for all of them.
I'll see if the fuse held well, but juging by the buzzing sound coming from the inverter board, I suspect something is shorted again......Leave a comment:

After a couple of weeks of service, the monitor died once again and now the boards on eBay are in the range of $50.
Not sure if it is worth attempting the repair again... Perhaps I had the wrong type of caps for the replacement?...Leave a comment:

Thanks for the advice, but as stated in my post, ALL of these caps WERE changed. The pictures show the board before the repair....Leave a comment:

Re: Acer AL2416 AL2416W 24" 1920x1280 LCD Monitor
Thanks everyone that contributed to this thread. I wanted to share my story here.
After being purchased from Costco, my AL2416 had been used as my every day work monitor for several years, along with another 24" Dell.
The problems started with fume coming from the upper left corner of the monitor, and shortly after the left side was completely dim.
Measurements on the board revealed a shorted Q6, a blown F2 fuse and bulged C36, C38 caps.
I replaced all capacitors...Leave a comment:

Hello,
I just wanted to thank everyone for posting their stories.
I saw smoke coming from the top left of my AL2416 a couple of days ago. The picture was fine for a few minutes, then the left side became dark and a buzzing noise could be heard.
After getting to the inverter board, I found
[LIST][*]One capacitor with bulged bottom[*]All the neighbourg capacitors had their color changed to brownish[*]At least one shorted FET (possibly another one as well)[*]Single Blown fuse...Leave a comment:
