Hey Guys -
I've got an LG 23MP47HQ which took a dive over the weekend. When adjusting the brightness of it Sunday morning, it went dark. Now every time when I plug it in, it shows the desktop for a split second then goes black and get the same result on different PC. Figured a blown cap, so started disassembly.
Took monitor apart but didn't see anything that stood out on the power board - below is a pic of the actual board. It was then I felt like a dummy as I realized the monitor had an external power supply. Tested it (19V 1.3A) with multimeter and all seemed ok, but tried another one I had laying around (19V 1.58A) feeling sure it would resolve the issue. Unfortunately, I got the same results.
I'd assume replacing the power board in the monitor would be the next step, but aside from that; is there anything else I can do / try first? Perhaps test each capacitor on that board?
Thanks!
