Looking at your middle picture, it does seem that a good clean around the IC socket would be a good idea. It looks like Q555 may have been replaced and there are signs of corrosion on the surface of R570. If you get the 7A12 working well then the internals of R570 are probably OK. I would certainly pull Q555 and Q575 and give the leads and sockets some IPA.

Best regards,
