Question about Sony STR-DE485 Receiver
Happened suddenly one day - the right speaker output is distorted - swapped speakers and wiring and it is definately the positive output for the right side. No obvious issues noted when looking at the solder points on any of the boards. Anything simple to check and/or replace?
The main issue is to determine where the distortion is coming from. Does it start in the front and and get amplified or does it appear in the output section only? This will require a fixed signal and an oscilloscope to trace. Check for leaky coupling caps or leaky transistors in at the diff-amp section.

Tips for a great answer:
Is it on all audio sources or only certain ones? Have you swapped the speakers Left-to-Right to isolate the speaker from the signal chain as a cause?
If it's only an analog source doing it I would suspect a bad audio cable or a switch somewhere in the signal path. Typically, it might be a switch you
rarely use, like a Tape Monitor. It's wise to occasionally (with power OFF) operate all manual controls throughput their ranges a number of times to wipe oxides from their contacts.
