Question about Onkyo TX-8511 Receiver
For no apparent reason (no lightening storms or abusive children in the house) the front panel of my TX-8511 will no longer light up with any indicators other than a dim red dot indicating power on, I think.
If this were my old Harman Kardon amp, I would check the fuses but there is no external fuse protection that I can see. No combination of front panel buttons seems to change anything.
Try powering the unit right down by disconnecting from the mains supply. fire up after 5 mins and see what happens. There is a separate transfomer for the standby supply(small red light) An internal fuse may have failed or the thermal fuse inside the transformer. If fuses blow as sson as you fire up = output transistors hay be short circuit.
