Its likely your looking at replacing some fets now, I'd inspect the inverter for visual damage to the 3 smd fuses and 4 fets....

Re: Acer AL2416 AL2416W 24" 1920x1280 LCD Monitor
Keith, your scaring me! I love my 245bw, so far no problems(I do hear a high pitch whine from it periodically, may crack it open and check for bad caps). My AL2416w is DVI, its definately blurry compared to the sharpness of the samsung, even with DVI.
I got these Fuses, they worked well, even though they are slightly less tall, they fit the pcb perfect. The seller also shipped them in 2 days, was SUPER fast in the united states.

Thought I would give an update, on March 16th I ordered 2x P5504EDG and 2x P2804BDG from a seller on ebay (Sisitronics).
They arrived today, I replaced the 2 fets on the puffed cap side first, leaving the original ones on the upper portion of the board,
and IT WORKS!! here's a pic, I'm hanging onto the other 2 replacements I ordered just incase.
My worklog.
1)Replaced 10x stock caps with 10x Low-ESR Caps.
2)Replaced All 3 fuses.
3)Replaced the 2 fets on the bottom half of the...Last edited by tgeml; 03-28-2011, 12:26 PM.Leave a comment:

Will do, I have a Raytek Infared Minitemp to take accurate readings with too, I'll take some readings on the original fets while powered on after 5 mins, as well as the replacements.Leave a comment:

Re: Acer AL2416 AL2416W 24" 1920x1280 LCD Monitor
Thanks for the tips, I'll be sure to be really careful! tonight i compared the fets from the side that had good caps, to the side that didnt. The fets on the bad cap side have continuity between any legs, and the back side, so im assuming they are shorted out, makes sense. The side with the good caps the fets tested good, but ill still replace em to keep matched fets.
Thanks again! I'm hoping my Hakko 936 and my desoldering pump help ease the desoldering.Leave a comment:

All of the Fuses test ok (Continuity), polarities of the caps match up to the silkscreen, I took a magnifying glass to the section of the fets that were near the leaking caps and they look like they have a slight "Melted" look just poking out of the sides, like they melted internally. I'm just going to go ahead and order 2x FDD6685, 2x FDD6690, and 3x SF-1206F400-2CT-ND. Just gonna replace it all for good measure so I don't have to open this thing again.Leave a comment:

Progress! I got my order from sev (He sent me 2 extra caps!) I also ordered 4 of the same from digikey, so I was able to replace all 10 caps. Once replacing them, the monitor powers up, but the left side is dim, is this indicating i should replace the mosfets? I Added a high res picture of the inverter as repaired so far, if you could give me your expert opinion that would be great! thanks so much for your help this far....Last edited by tgeml; 03-11-2011, 05:30 PM.Leave a comment:

Figured Id Share my story as well,
I'm having the traditional power on/off problems related to components on the Inverter board, being fairly knowledgeable and having a great hakko 936/desoldering equipment, I removed my inverter to find the 4 north caps(C34-38) not domed, but leaking electrolytic fluid from the bottom, all the other caps looked fine.
I desoldered the caps and ordered a kit of 4 Nichicon Low ESR caps(100 Microfarad/35v) from ebay, from a guy in my state none the less, waiting for...Leave a comment:
