Re: Acer AL1916W LCD Monitor Power Problem
Acer monitors are notorious for using several different power supplies.
There is no way anyone can make suggestions without seeing yours.
Please include some photos of top and bottom of all boards, using the managed attachments feature you will have to resize to a maximum of 2000x2000 pixels Try to get as clear and detailed photo as you can.Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

Re: Acer AL1916W LCD Monitor Power Problem
1) If you hookup a working computer to the Acer displaying your favourite wallpaper, can you see it if you shine a flashlight on the lcd?
2) Check the voltage regulators on the logic board. They are U101 and U102.
3) When you press the on/off button, what is the voltage on pin 4 on the connector between the power and logic board? Does it change when you presse the on/off button?--- begin sig file ---
If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.
We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.
Please do not post inline and offsite as they slow down the loading of pages.

Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

I have the same power board and I am having a hard time getting the schematic for it, I was hoping that you would be kind enough to send the part number information that is stamped on top of IC802.
Thanks
