Question Recapped Acer Monitor Black Screen

[grgrgrs]

I've got an AcerG276HL,I've had it for about four years, it does not display anything. I just replaced the capacitors. Currently, the power button LED will now turn on as normal, but the monitor will not display anything. What's my next step? I've replaced the AD adapter and tried different HDMI cords and different inputs (laptop/desktop). Thanks!

I'll add that whatever I plug the monitor in to recognizes it's there.
