SOURCE: klh r7000 no sound
Like I wrote, I had a similar problem with popping and then no audio for an extended period of time. I found the solution on another site, http://dexsoft.com/blog/?p=15
Apparently the solder joints are weak, and just as the blog described when I opened up the receiver I saw the same scorch marks from overheating. Just as the blog described, I added solder to each of the joints in the photo and have had no problem ever since.
I am no solder expert, this is my 2nd time, but all I did is build up each of the joints and I have been listening to music, playing movies in surround sound with no problems, no popping for the last 2 weeks.

Take the top cover off with the unit unplugged, you will see the fuse just beside the big capacitors, diodes and the power transformer(and fuse current rating is written on the board) . The problem with your receiver is worse than a fuse I suspect. So, before replacing the fuse check for short circuit. If there is a short circuit specially power amp section(which is common to fail) the problem might get worse when you rplace the fuse without checking it. :)
