Question about Sony STR-DB840 Receiver
My receiver is now making some strange noises which sound like a 'crackling' or 'arcing' then losing some of the channels on the cinema surround sound. The same noises are heard on the two channel option, but the two channels operate. The crackling noises seem to reduce as the receiver remains powered on for some time. Any suggestions for causes and solutions?
I am afraid not. That crackling is a component in one of the solid state amp circuits starting to fail. These are all soldered into the printed circuit board. This could be a difficult repair to find an intermittant component. Depending on how old the unit is and how much it cost will factor in on if you have it repaired or not. Rule of thumb is that if the unit is two to three years old and cost less the 200 to 300 bucks you should not invest more then 100 to 150 bucks into it. Good Luck

Have you tried the "Simulated" surround setting?
If you don't get sound in "Simulated" mode then you have probably lost the surround channels.
If you do get sound then your "Media"
is not recorded with a surround "Track". or the surround "Processor" may have issues that need to go to the repair shop.
