Mackie SRM450v2 PFC Repair & Keysight Scope Signs of Failure | Power Electronics

Hi,
In this video I repair the PFC circuit on a Mackie SRM450v2.
Whilst editing the video, I had time to read the on screen firmware failure message. I had previously thought it was a normal boot message where one can change the language etc.
I have spent over £1000 on firmware upgrades so will be speaking to Keysight before attempting any firmware upgrade.
