Hello everyone,
This is the continuation of a former thread where we worked on the power board. This is about the main board photos attached of everything, but especially higher resolution photos of the main board.
Thread part 1:

As I had mentioned, when plugged in this monitor shows the amber light on the power switch and there is no response to keypress on the switch panel. Someone mentioned that it could be a problem with a corrupted eprom, but for some reason I am getting 80 ohms resistance on the 3V rail. Also checked the switch panel and it looks to be OK.
I removed the 2 electrolytic caps and checked them - their values and ESR are ok. Checked the voltages on the voltage regulator on the main board, and I get 3.3V on left leg, and 1.8V on right leg, so that looks ok.
Not sure what to check next. Any ideas?
