Having problems with your Altec Lansing AVS 500 Computer Speakers ?
Rippling vibration in sub woofer seems to be transformer related
The power supply outputs DC voltage so there is a 2200uF cap inside it. If this goes bad you get a humming out (usually from the base speaker) even at minimum volume. Inside the base there are 3 TDA2007a 6 + 6W stereo amplifier 9 pin inline ICs, one voltage regulator IC, 5 other ICs, 2 more tiny transistors, 1 2200 UF capacitor, plus a bunch of small caps. Usually one of the TDA2007a amp ICs has gone bad (in my case it was the one that drives the base so the popping sound was coming out the subwoofer). The TDA2007a seems to be a faily common audio power amp IC. The main problem with the Altec Lansing AVS500 is that there are no screws to be able to take apart the base so you have to brute force pry it apart and then the jacks and controls are also glued onto the front plastic face of the subwoofer so that must be carefully pryed apart also to get the small circuit board out to be able to work on it. It's all too easy to break something if you're not carefull, but what the heck, if the speakers aren't workiing you don't have anything to lose and if you are proficient with a soldering iron and have or can get a TDA2007a audio power amp IC you might be able to repair it. My own speaker problem was easy to determine as one of the TDA2007a was overheating super quickly after plugging in the power. Good luck to anyone else attemping a repair.

Hi, I have a pair of Logitech x-320 speakers. Only the top portion of the right speaker plays when plugged into the sub-woofer and only faintly plays. However, both speakers on left and right play if I adjust the plug into the sub-woofer. However, the vibration of the woofer moves the attachment ( I can't fully attach to play both speakers). Is there something to clean or adjust the connection as that seems to be the challenge? Thanks!
