Having problems with my Zafira car radio. Front panel shows correct radio station, but no output on speakers, when I switch radio on I get a slight "clicking" noise from one of the speakers. Purchased a replacement radio from Ebay, initially radio worked fine, then 2 or 3 days later, exactly the same fault. Has anyone got any idea what this can be?

There is a possibility that one of your speakers is causing the fault.
