Electronics Repair Questions? Ask an Electronics Technician
Hello and sorry you're having problems. When did this problem occur- were there any storms, power outages, etc. that may have been a catalyst?
Additionally, have you tried disconnecting all HDMI cables and speaker cables (with the receiver unplugged from power) then plugging ONLY the receiver itself back into power to see if it will power up with no external connections?
Please let me know when you're able to see my reply.
