Sounds like something is pulling your voltage down which is obvously having a knock on affect on the rest of the circit

With power off check resistance between the 9v pad and bottom end of R32 where it meets R33, then check resistance keeping 1 probe on the R32 / 33 resistor junction and the other to ground

Also with power off check resistance from 9v pad to the bottom end of R31 where it meets C13

If you’re getting 9v at the top end of R31 then dropping 3v there could be a solder bridge around that area check those solder joints under magnification

When you look at that part of the circuit and from your description either there’s a bridge on R31 or something possibly C13, 14 or 15 is pulling power to ground
