Alesis Multimix 4 buzz

Hi all

I have an Alesis Multimix 4 mixer, which I have been using for a couple of years now, and a Rode NT1A mic to do some home recording. I did buy it secondhand and it worked fine except for a slight headphone hum, which didn't affect the recording.
This morning, however, there is a definite loud buzz which also transfers onto the recording, thus rendering the DAW unusable. I have searched this forum for posts and found about 8, one of which discussed replacing capacitors. I am no electrical expert but I deemed that this would be inside the realms of my skills and tools available.

I have taken the box apart to reveal the circuit board and it is nothing like the one discussed in the previous posts I found. The capacitors all look to be in good condition with no apparent bulging.
So, the obvious question is, where to go next other than buying another one?

Any help will be gratefully received. I do have an AVO, but after that, electrical diagnostic tools and knowledge of capacitors etc is limited.
This is my first post, so please be gentle

many thanks

Mike
