Power issues with my receiver.
The issue started with the receiver. Suddenly the “On” blue light, “standby” red light, and “recording” orange light all came on and the TV didn’t came back on again.
Side note: whenever I connect the black system cable to the TV, the light on the TV goes from blinking red to blue to a STILL red.
My guess, perhaps I was using an incorrect power cable, but never had an issue for the first few months.
