808 just quit after 4 good years
As the title indicates, my 808 just developed the no audio issue. It started about two months back and I've been leaving it on to help keep it warmed up and functional.
I just sent off for the repair after finding this thread and the link to Onkyo's website for this issue.
Once I get it back, I plan on adding a RAM sink to the chip to keep the temps under control and hopefully prevent this from happening again. I may do a small and quiet fan, too.
I'll update with more findings when I get them.
