The other day i stumbled upon a rather recent monitor in the dumpster and thought to myself that it would be just a quick cap change on the PSU to get it working again, but i was wrong.
Firstly, this monitor has an external PSU, which i do not have, althogh it did rig a couple wires up to the board for power, so there must be something else wrong.
At first i tried to give it power, but with no success, i thought that the main board was dead, that was untill it gave away some light and a "no signal" image for about a second and then died again.
I then pulled out my DIY RF detector to probe the crystal and the results were rather interesting.
It seems like the crystal is off untill i press the on button and it starts pulsing on and off in about one second intervals, then if i press the on button again at the right time the crystal activity jumps up for a couple seconds and the monitor powers up for about one second and dies.
Not sure what it could be, maybe the internal DC-DC is faulty, but then it wouldn't work at all if that was the case, the processor seems allright, i had it plugged into my PC and had a glimpse of my desktop for a second till the monitor died.
I'll try to get a more graphical representation of the crystal activity tomorrow.
Thanks.
