I hope someday stores like Amazon will rate based on expected lifespan. I just had a receiver die. It was 8.5 years old, not really outdated... But those kinds of things should last a lot longer!
If it's just a capacitor that failed, it might be repairable for a few dollars. Electrolytic capacitors unfortunately have a finite lifetime, which gets worse with higher temperatures.
(I also was ready for Dolby Atmos and EArc... Things that most people don't care about.)
Do you think it's worth selling the broken receiver on eBay with no reserve?
