I have a klh # r7000 with no sound in any mode. tried plugging in different speakers, no difference
I have a KLH R7000, Display works, switches to all the Component Systems but there is no sound from the speakers, from radio or other component hookups. I have disassembled and have not found any speaker fuses. Does this Receiver have Speaker Fuses or does it have some kind of circuit protection that needs to be replaced. Thank You
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. :)
When I watch movies, most of the talking is directed to the center speaker. During surround sound, this gives a more realistic environment, with voices coming from the source (center where your tv is) and ambeint noise coming from the left/right corners.
look on the component for details or in the schematic of the device
if u can find a voltage requlator that matches the same specifications as in ur system then u will b happy
till then u will need the manufacturer requlator
