Opening an AV40. I'm stumped.

I am having issues with a trs input and wanted to get to the circuit board to troubleshoot. I've removed about 20 screws from the rear of the AV40 (some are still on the unit....they turn and turn but don't come out) but the rear panel doesnt seem to want to budge at all. What's the trick?

  • Hi,

    Thanks for posting!

    This sounds like it may be hardware related. Warranty and non-warranty claims cannot be handled here on the forum but I can point you in the right direction! Here are a couple of options that you could choose from:

    • Submit a Warranty or Service Inquiry with our Technical Support team by logging onto the M-Audio Support Page. Select Warranty or Service Inquiry from the drop down menu. This will not require a support code.

    or

    • For faster support, call or email your nearest Support Office or International Distributor. Select your country to find the nearest office.

    Make sure to reference or link to this thread to help out the support team.

    I hope this helps! Let me know if you have any additional questions.

  • Hi,

    Just remove the 10 screws around the outside of the back panel. Then you need to pull the panel back, I find using a pointy screwdriver into one of the screw holes to lever it out.

    It takes a bit of effort but it'll come out. Its just there is a bit of weight on the bottom and the panel is a snug fit, so give it some leverage.

    The screws around the centre that are hard to turn is because the other side is coated in glue. They hold the heatsink in, and also hold the plate covering the transformer.

    Good luck.
