Welcome to the forum! Definitely need photos of the top and bottom of each board per link below. Acer uses several different power supplies and we'll only be "guessing" without photos.

I think AL1914 uses external 12v Power Supply ????/so would look at the Inverter Board in the first instance.

Well, for sure you have at least 5 bad/bloated caps. See my marked up pictures.

Replace them with caps from this list.

If you are in the USA, you can order from digikey.com and use Panasonic FM series if you follow instructions below.

edit: Most here will recommend that you replace ALL the caps since at least 5 of them went bad and the others may be bad as well even though there is no visible bloating. Caps can still be bad with bloating. They can have out of tolerance uF or high ESR (ohms).

Recapping everything should cost less than $10 USD.

The cap with the "K" vent just right of the inductor coil (green with copper windings) might be a Rubycon cap. You can leave that one installed if you want.
