Did you check the panel light fuse & the 2 radio fuses? The best diagram I could find is
here, it might not be right for your car but the handbook should have a diagram
If you are talking of the PCB they can't be repaired. My pcb failed on my 2006 Roadster, I found with the lights on it all worked so wired the lights on permanently. There are 2 micro relays on the board one with the lights on one without.
Do your instruments light up with the lights on?
