    Need help with fixing pc subwoofer+speakers please

    Thank you on your compliments gentlemen. I seem to have found the REAL problem. I followed the path that krizblue NZ pointed out to me and I found out that it went to one of the cables that connected to the volume control (one of six). In order to further assess the situation, I had to remove...

    well so I resoldered the joints on the TFA9842J ICs and something weird happened. The first reading I did showed a reading of 10V on pins 2,6 and 8; and 6V on pin 7. However, after unplugging, waiting a few seconds and replugging, the readings went back to 0 on those pins. Only pin 9 still shows...

    So i guess you have found the problem Kris Blue NZ. The TFA9842J ICs are not showing correct voltage values. Pins 2,6,7 and 8 show a voltage of 0V on both IC's, except for pin6 on one of them that shows a value of 0.2 v On the other IC's there is a voltage of 12.2V on pins 8 and a voltage of 0V...

    Thanks for your help KrisBlueNZ! This is a set of logitech x-210 speakers I hope that the following pictures show the model number you were asking me: I found this on one of the TFA9842J, is it a dry/bad joint?

    So, in case it's not readable in the pictures, the IC's are both marked utc4558 and the white pasted items are marked TFA9842J. The TFA9842J were in fact against metal prior to disassembling. As far as I can see, there are no capacitors bulging. Ont the last picture is the bottom of the volume...

    Gryd3 Thanks for your reply Gryd3. The first picture has the amp on the left and the remote volume control on the right. The 4th picture shows that "white past" I was talking about, and the last photo shows the socket for the pair of speakers (not the subwoofer speaker). I'm really just starting...

    Need help with fixing pc subwoofer+speakers please

    So, I got a set of logitech x-210 speakers 4 or 5 years ago(probably more). They are not under warranty any more. About 2 years ago, they started to behave erratically. The led light that lights up when the speakers are on, sometimes, went off (as well as the sound). Or when I tried to turn the...
