We have a marantz amplifier and wharfdale speakers - bought them new about 8 years ago? and we have our TV / Sky / DVD player all running through the amp / speakers
about 3 months ago I turned the TV / amp on one morning and got a fright when the speakers started crackling like loud popcorn or very loud static.... since then it's done it every day when we first turn the amp on for about 10 seconds, then it stops and normal TV sound resumes from the speakers.... but the last 2 days the crackling has got louder and lasts for about 20 seconds.
does anyone know what the issue / problem might be? - as it was working fine up until about 3 months ago - and we've not changed any settings / cables.
I cannot check the TV by itself as it is all going through the amp (turning TV volume up / down does nothing)
any advice would be appreciated
