Question about Acer AL1912 19" LCD Monitor
I have checked everything. Monitor keeps saying it is self testing and it is working fine so check monitor plugs and computer power supply. I did this. It all powers up but nothing comes on the monitor besides this message repeatedly. It is a n e-machines...2yrs old
The self test thinks nothing is connected to it
it might be the cable or the input circuit.
not an easy issue to verify if you only have one input.
most often its is the internal board with a failed input circuit.
you can only open the unit and test the vga cable continuity.
as most have a 1 year warranty you might want to check on yours.
