AOC monitor power board
Hello,
I have a problem with an AOC q277PQU monitor. The screen is black (no osd or image) while the led is green and usb ports are powered.
I was excpecting a dead capacitor on the power board, but the problem seems more serious.
I can’t find a spare for this power board, do you think it’s recoverable?
Thanks.

Thank you for your helpful answer @oldturkey03
I am disappointed becasue the 2 yr warranty is overshot by maybe 3 or 4 months, and it was a very decent screen for money.
Here are the labels on the panel:
Thanks

This little chip is just at the back of the burned zone.
Do you know what it is?

@ramaro that is a Schottky SK84 SMD Diode
Maximum Recurrent Peak Reverse Voltage 40V
Maximum RMS Voltage 28V
Maximum DC Blocking Voltage 40V
Cost ~1.00 USD maddening isn't it?
Go ahead and replace it and see what happens. At this time it can't cause any more damage and may actually work. Let us know how it is going.
