Acer laptop won't turn on after dissasembly

I recently bought an old Acer U13S laptop. I took it apart to use the motherboard for a project, and now I can’t get it to turn on. To clarify, the lights are on, the fan is on, the CPU heats up, and the drive makes noises, but the screen doesn’t show the Acer logo, or boot to BIOS. I checked the RAM, and disconnected and reconnected the CPU. When I plug it in to an external display via HDMI, it shows nothing. The screen turns on, ever-so-slightly changing colour. Does anyone know why this is happening, or how I could fix it?

Answer this question I have this problem too

If the screen only changes color slightly when you turn on the computer, the problem could be with your LCD display inverter. A laptop’s display inverter is a small circuit board, usually about the size of a pen, that illuminates the screen. If the inverter is damaged or not hooked up correctly, then the screen will not light up properly.

I would check the inverter’s connections at both ends, and then replace it if damaged.
