    Is it possible you missed a breaker? I am curious though how the TPC is powered if the LVPS is bad.

      TCP is powered by 24V standby supply, not from LVPS. LVPS powers on backplane (and boards) and EVB (fans, motors..)

        Yep, the TPC is indeed powered by the Standby PSU, because if I remember correctly, it is the TPC who eventually sends the POWER ON to the LVDS... I had a schematic of how stuff is powered on those machines once, because LVDS related faults were the most common, but I can't find it right now. It was a pretty public thing and provided to me by Christie.

          Elia is correct. It's powered from the 24 volts. If it was not you would not have control over the projector....

            Of course you are all correct, but the standby PSU still takes its inlet power from the same 100-240volt power input so if the TPC is running the projector is likely getting power.
