M602 Speaker Problem,.. Popping Sound

\015 I have the same problem as others who have previously posted comments. My speakers make a popping sound, as if the power is being continously turned on and off for the M602 Altec Lansing speaker system for the iPod,.. It doesn't start off doing it, but after about 5 minutes the speakers shut on and off. I assume it's something to do with the power and not an actual physical problem with the speakers, because they sound great until the problem arises which is usually after about 5 minutes. Maybe i could simply buy a new adapter cord? If anyone has any ideas please let me know\015

Answers :

This worked for me on my M604: Try inserting/removing a headphone plug into the jack several times to see if that clears the problem.

\015\012The "popping" sound is very similar to the sound that the unit makes when inserting headphones into the 'headphone' jack on the back of the unit.
\015\012
\015\012The jack has a contact switch that triggers a relay inside the unit. If that contact switch is 'on the verge' of making contact, slight temperature changes may cause deform closer to it's contact target. The subsequent capacitance build-up and discharge across the gap could explain the cycle of popping noises after the unit warms up.

Popping sounds I have had these speakers for a few years and LOVE them, but about couple years ago, I've been getting popping sounds from them.  I hate to get rid of them because I know the speakers are working fine so I've done some research and it looks like the problem is with the control center.  Logitech will not repair it and a control center is hard to come by on ebay so I have couple of questions, 1) can I repair the control center myself or 2) is it possible to replace the 6(?) pin plug
