Just spent the night gutting a couple of 17" acer monitors that was donated to us from Brandon's work. After looking over the boards, it seems that a voltage regulator is failing on the video board. It is an SOT223 1.8v reg. Some of the Vregs failed and dropped to 1.2v some ended up failing and went up to VCC. The vregs that hit VCC killed the main chip on the video card and will not be repairable. There should be at least 5 of the Acer AL1716 that can be brought back to life. If anyone is interested in picking up some vregs to fix this monitor here is the mouser part.

Ben, at some point would you mind walking some of us through diagnosing that? When it comes to electronics, most of my troubleshooting knowledge is theoretical, not practical and I'd like to start rectifying that.

Yeah, Sure thing Mark. 70% is googling it to see if anyone else has figured it out.

For the BEN'Q monitors(we have a bunch of them) I have verified it is an issue with the inverter circuit. These are going to be a little more to repair.




If anyone wants to take a wack at repairing the BenQ's we have ~18 of them.

4 of these per monitor



2 of these per monitor

and 1 of these per monitor
