Novation Xstation 49 power issues?

Hi folks,

Thanks in advance… I have a Xstation 49 that, on USB power lead, only 4 of the far left button LED’s light up, and it will not continue to boot.

I see that the PSU is integrated into the mainboard?? I am super novice, but I do have a multimeter, and am wondering if I should just try and sell this for parts, or if there’s any foreseeable repair I might could begin …

Thanks
Boz
