Question about Logitech Z-2200 Computer Speakers
Hi, can you please elaborate on "sub is starting to pulse". Assuming initially that by pulse you mean that the sub produces a thumping sound when turned on, then: in some cases, this would be even considered normal; if you have not experienced this before except lately, then it is possible that the amplifier powering the sub is in question. Chances are that you have a leaky/defective capacitor in that section. The basic repair would involve remove/check/replace (if needed) but if you are not comfortable working with a soldering iron and a VOM, it would probably be best to have an electronics tech work on it. Hope this works out for you. Good luck.
