Good afternoon

I have a Philips TC35 that went away with a power issue and AVR showing in Amber, multiple leads and different simulators, still showing AMBER>

However, if BPMs are OVER 120 - AVR turns GREEN, under 100BPM, AVR turns AMBER.

Went away for the first time and they replaced the PSU due to blowing fuses, sent it back when received as it was damaged in Transit - They confirmed the AVR issue, however nothing.

Anyone else seen this?
