Do I have a blown 3.3v regulator?

Hi everyone,

I am trying to diagnose whether my 3.3v reg is blown on my APM 2.6.

I have tested the IC2 port and there is 5v there, however at the reg itself, on pin 5 I found only 3.3v. I have attached a photo that will explain what voltage is where more clearly. The reason I think it is blown is I read somewhere that if there is a blown reg the compass offsets will be high, which they seem to be.

I don’t think this is an original board, try measuring the regulator.
