Hi Guys, I have a Sony DAV-S500 (yes, I know it's old, but only 3 years!), where the sound from the left front speaker cuts out. It might go for a couple of weeks without this happening, and then do it every few minutes for a few nights in a row. It occurs on all sources including Sky+ and DVD. When it happens there is a hissing sound from this speaker. Any ideas on what the problem might be? Anybody else with a Sony had a similar problem - if so what did you do about it? I don't want to start going down the repair route if this is going to end up costing nearly as much as a new system! Any ideas would be much appreciated. Thank you in advance.
