Re: Acer AL2416W No Signal Until Warm

Tonight the monitor flickered off for a second. I suspect it is going to fail very soon. So I got around to opening the cover.

Even after 15 minutes the power supply is still so hot that I can't touch it. So it seems fairly obvious that it's the power supply that is failing. Nothing else appears out of the ordinary.

There is a heat sink plate glued down over most of the board, so it's not worth trying to even service any parts. They're kind of rare, but it looks like I can get one out of Canada for $50, unless...

I have a fairly old Acer AL2416W that is my secondary display in a 2-display setup with a Quadro FX4800 video card. Yesterday I temporarily installed a Quadro K4200 card and realized that the problem lies with the monitor. (A couple of red herrings made me think video card.)

This is NOT the 2-second-off problem. I have had that happen to both of my monitors in the past when they were still under warranty.

The monitor gets enough signal to wake it up, but looses the signal and goes back to sleep until it has warmed up a half hour later.

I almost forgot...

I'm Rick, an electrical engineer with a failing Acer AL2416W. I didn't find my symptoms listed in a search. So I guess to start a thread I need to make a posting.
