My A5s are way out of warranty, and I've just started to get the snap, crackle and pop noise with no input connected, and regardless of volume setting (it needs an input to get out of sleep mode, but thereafter unplugging the input doesn't stop the noises).
I took the guts out of the powered speaker and spotted a blown 470uF capacitor on the smaller PCB (top was bulging). I replaced it and its neighbour with good quality replacements (leftover from a mobo repair with the same problem), however that didn't fix the problem.
I've looked around the forums and there are plenty of people who have had the same problem going back 4/5 years, but couldn't find a clear answer as to what the problem might be. If anyone can point me in the right direction, that would be fantastic.
Failing that, I've got a Sonos system with one spare power amp device, and I'm thinking perhaps I could rip the electronics out, put a couple of crossovers in and run the A5s as passives.
Has anyone tried this, or got any suggestions for how to go about it?
