I recently bought an Acer XZ270U off facebook marketplace that does not power on.
When I plug it in, there are no sounds, no lights, and the display remains off.
I already tried replacing the power supply that it came with, to no avail. I am guessing it’s something to do with the main board? I went ahead and opened it up, here is a picture:
Anyone have any ideas?

@redmaus looks like your main board is on the Fritz. The two larger capacitors appear to have swollen tops and thus have failed. At minimum I would replace all caps on that board.

OK Thanks for the help, I will look into that.

@redmaus remove the metal casing around the board and take some more good pictures. that way we can see the actual circuit board. The boards on the bottom of your picture are the LCD driver boards. Those are considered part of the panel and not really fixable. Your issue appears to be related to the board under the metal cover.
