    Logitech X-240 Static in Right Channel

    Hello,

    I have an old Logitech X-240 that I do not really want to get rid of, but it has a ton of static coming out of the Right Channel when idle. It can be drowned out when there is music playing through it, but I had a problem where the static was too much that the music could not be heard through the right at all.

    I am not sure what type of components to check, as all of the resistors, capacitors and the fuses look solid. Would it be the audio chip, or the odd black chip that looks like a 555 timer that is at fault?

    Any ideas?

    If you have ruled out the chance of bad speakers. I'll start by looking for and reflow any suspicious joints. Then I'll try reflowing the big output ICs then reflow the smaller ones and try playing. If that doesn't help I would try replacing those smaller Electrolytics then go at the bigger ones.

      If both output ICs are the SAME, swap them and see if the symptom swaps too.

        Those small 8-pin IC are dual op-amp. So do as JTS suggested.
        What are the P/N of those two power amp ICs?

          old X58 triple channel board... memtest86 memory speed?
          by eccerr0r
          Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.

          Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...

          Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any...

          Reverse engineering of 18650 4-channel tester
          by spleenharvester
          Hi friends

          I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...
