Presonus Studiolive 32.4.2Ai digital mixing console with firewire 800 interface option card - for repair or parts

Presonus Studiolive 32.4.2Ai Digital Mixing console IN NEED OF REPAIR
Includes power cable and firewire 800 cable.

Please Note - This Mixer is being sold "AS IS"
Please read my Fault Description below!

Fault Description:
The Mixer powers on fine, but, after a while, can randomly switch between various scenes selected. i have attempted to repair / debug this board, and to the best of my knowledge, I have narrowed the problem down to a bad solder joint or damaged circuit track on one of the circuit boards (pcb). i've discovered when pressure is applied to a certain point, the mixer works as normal. The circuit board i'm refering to is the one on the far right which contains the "master control" section. The "scene select" push button works intermittently, which to me indicates that the problem most probably lies in around this area of the circuit board. (i've highlighted this in one of the attached photos)
Everything else on the mixer is in good working order - eg. - the internal Power supply, all led meters , all faders, all 32 input preamps, the firewire ethernet option card and the usb wifi dongle, lcd display and so on.
This mixer is in very good cosmetic condition otherwise, has been used in a studio environment and never for live gigs.
I am selling "as is" as i don't have the tools required to attempt any repairs, but it should suit any electronic enthusiast with repair skills, or somone with a similar mixer model looking for known good spare parts.

The mixer uses a firewire 800 interface card and have been working with no issues on a windows 11pc with a pci express firewire 800 card using the firewire 1394 legacy driver.

I cannot confirm latest mac o/s compatability.
