A while back, I sent an S271HL monitor in for warranty repair. The issue was that the screen would not activate and the only thing that happened was a flashing amber power button instead of a steady blue button. The problem is that I got it back with the same problem I sent it in for. 
I got the monitor back today. On the first of two service order pages, under Problem Decription, I see:
c:cx told that unit dsnt turn on, only a power light flashes
a:did a self test, no go, so informed the cs about repair, cx agreed
r:scheduled the unit for repair
On the second page, I see this:
Computer Data | Accessories
No Acessories (No Box)
Software & Other Remarks:
surface scratches, no power
(Note from this poster: surface scratches? Where? I treated this monitor like it was made of crystal.)
Diagnosis / Repair:
Reported issue not noted. Monitor powers up with good, stable display. Monitor passed intensive system burnin testing over weekend, in excess of 63 hours, with no observed issues. At conclusion of extensive, intensive burnin testing, powered monitor off and back on several times; always powered up with a good, stable display, no issues noted. During testing, powered monitor off and back on several times; always powered on consistently with a good, stable display.
===============
So my friend has a power supply for his Acer monitor (a smaller one) that has 19v and 2.1A, just like mine. So I borrowed his power supply to test my monitor and I had the same issue: a flashing amber power button.
So the question is: Has anybody else ever encountered this with Acer? I'm going to call them, but I wanted to see if there were any opinions here at the same time.
