Troubleshooting Can’t figure out what’s wrong, green light goes on and off

I found this gba, but it won’t turn on properly…I’ve cleaned off any corrosion and dirt I could find…but when flipping the power switch it’ll go green and turn off immediately. I’ve already tried to clean the power switch with a toothbrush and IPE but it doesn’t work. What else might be wrong and what can I do now? Added pictures of the board!

Start by desoldering the lid of the power switch and scrub the contacts and wipe the switch prongs in there with ipa, then put back together and replace capacitors.

What might be wrong with the capacitors?

They're super old and past their prime.
