D-Control Main unit no lights

[Vedat]

Hey all.
Earlier this year I had to replace the LED PSU on the fader unit.
And few months later fader unit leds and the main unit leds started flashing. And then Main unit leds died completely, including talkback, oleds, everything.
However, the unit kept working as normal, buttons worked.
Today I replaced the LED PSU on the main unit but the lights didn't come back...
(Fader unit LEDS came back after the replacement)

At the moment I am anxiously waiting for the courier to bring me the Logic board PSU to see if that helps.

My hours are counting fast towards an inoperable suite, so any insight is much appreciated right now..

cheers
