Loop LED on the AU2 board not looping/flashing?

April 5th, 2023
  1. . Check M6808 PSU supplies are outputting the correct voltage.
  2. Switch off mains supply, remove all processor board and clean PCB edge connectors with suitable electrical contact cleaning fluid before firmly re-inserting them. If the loop LED is still not looping/flashing following this action then it likely there is a board fault. Contact TVC customer support for further advice.
