Re: Acer AL2216W Dead

I have tried your suggestion but unfortunately it did not work. It has not powered up yet. I am so suspicious about the logic board and am thinking about ordering one??? Anyone has any more suggestion to test the logic board?

OK. here it is with pictures...if you need any more measurements just shoot. Thanks peps....

Re: Acer AL2216W Dead

I did and got the same readings again. Output 4.9 ~ 5.0V and 24 on the fuse. 5v and 14V is showing on all pin-outs as written on the board right beside 16 pin connector. I have checked mosfets on logic board too- got readings of 3.3 middle pin, input 4,9V and pin 3 4.7V.
I have the power led AMBER all the time and it would not turn on nor show picture or even flash for a second or anything.

Re: Acer AL2216W Dead

Hello All,
before I start i have to say a read a lot of threads and yes they are so interesting and carry a lot to learn. Now, my problem is almost the same as yours, but a bit different. My monitors led is amber as soon as I plug it in to 220V and stays like that forever, cannot turn monitor on or get picture or anything else. Same monitor, same power board and here´s what I have in regards to measurement. Secondary output (to the logic board) is OK i guess, on 13.8V I have 14.2 and on 5V I have 5V. Checked the fuse on logic board just fine. All the...
