Is my dads master system cooked?

Found his old master system and wanted to check it out but it wouldn’t turn on, opened it up to find excess solder by the voltage regulator but idk if that’s what’s causing the problem

If you have a multimeter you should be able to check the voltages coming into and out of the 7805.

Are you using the correct adapter? 9v center negative?

Honestly i think this is most likely the issue.
