Re: ACER GD245HQ totally dead no power
My symptoms was the same:
If I turned off the monitor, it no longer turned back on anyway I pressed the power button. The LED below it did not light up.
When I pulled the cables (cord+hdmi)out of the monitor, and leaved there for 2 two days, it returned to normal state, until I tuned off the monitor again...
I replaced the caps. But it didn't help.
Thanks for this forum I ordered the suggested chips from

And I replaced the 2 suggested regulator chips. And the problem has been solved! Thank you lotas and willthrom!
I leave some warning here:
A very hard solder material was used + conducting bands are very tiny under the pins of the chip, and it easy to tear them.
I used hot gun to remove the regulator chip. And I used bit more force to tighten the chip at the first chip swap. Resulting I have to rewire the connections under microscope. But I solved!
