    I'm trying to fix a sansamp DI for someone at work. During a show, it just stopped working for him. We can get it to pass a signal with the battery in, but not with the power cord and the LED isn't going on at all. I opened it up and used a multimeter to confirm that it's getting 9V from the adapter... also from the battery.

    Other than that, I'm not sure what to check. I'm working on getting the board out of the box, but that is tough due to the construction. I have reflowed all of the solder in the meantime and can confirm that it's not a cold or cracked joint.

    Any other ideas?

    It sounds like the unit may have been damaged by using an incorrect power supply and a component may have been damaged. It's best to contact us for a return authorization so the unit cab be repaired. It's not an easy repair for the average person.

    Did you find the solution? I have the same problem. Yesterday it's just gone to bypass with no LED and no switching reaction.

    I couldn't figure out the issue. I reflowed everything and did what I could, but it was an issue beyond my abilities.
