We have two AL1717 LCD monitors purchased at the same time which have spent their entire lives in the same machine room.
One has been on for years, mostly in standby mode (no video from the server it is always attached to), and this one works great.
The other was used for fixing whatever machine in that room broke, and was usually off with no power, being on no more than a month total since it was made. This is the one that is now failing.
When power is applied and the power button pressed nothing happens at first. If the power button is pressed repeatedly, over 30 seconds or a minute, the power LED starts to blink, but nothing shows up on the display. Eventually the LED goes solid and the "ACER" screen comes up. After that it works normally.
Have any of you ever serviced one of these, or a closely related model, with these symptoms? Other than the usual "check for bulging/leaking capacitors" what should I be looking for? Since it works, eventually, I'm guessing none of the fuses are blown and some capacitor in the power supply is failing, taking a long time to charge up and provide adequate power to the logic and inverter sections.
The one thing about the environment that has changed recently is that a slipping belt on the AC unit was recently replaced, so the room is now a few degrees cooler than it was a couple of months ago. This display was moved to a warmer room, and is warming up for a couple of hours before trying it there, just because I'm curious if it will work better at a higher temperature. It still needs to be fixed though, because it needs to work in the machine room.
