Basically I got a ACD 20" model: A1081 for free. They were going to dispose of it at work, I asked them what the problem of the monitor is and they said it has a power issue. I asked if I could take the monitor hoping that it would be an easy fix. I brought it home and realized there is no power brick, luckily I was able to borrow my cousins power brick. I plug the monitor in, to just the power, but nothing happens, the power light doesn't even come on. I was wondering if the power light comes on if the monitor has no video signal? Also, is this a common issue with these monitors?
