Hi,
i've got a Onkyo TX-NR535 AV-Receiver that does not power on.
It only clicks and nothin happens. Not even the Display is lit up short.
I can force it to power up "completely" if i remove the power connector to the AMP Board (the one directly from the transofmrator) OR if i unplug the HDMI board from the vertical board (leaving any cables connected)
The vProtection and iProtection both are at 0,5v measured through the vias beneath the CPU and using ground from the P9001 connector
The problem stays even with the preAmp Board removed. I suspect the problem be either on the HDMI Board or the Amp Board, but i can not find any obvious problems.
Any ideas what i could test?
