    MV1B1 Stuck in service mode

    Thanks for the detailed breakdown. Can confirm that none of the CRE401 pins are touching. If the causes for both the dip switches and the test button were in two almost opposite parts of the board, then it is curious that both issues started happening at the same time. Unless there's some other...

    MV1B1 Stuck in service mode

    I haven't, but the same issue happens with a different supergun and does not happen if something else is connected to the same supergun. So I don't think that it's a problem with the supergun, unless it's a hardware fault on the MVS that was caused by the supergun.

    MV1B1 Stuck in service mode

    Can confirm that the display is accurate. There is a voltage adjustment knob but the lowest it gets to is 5.18 sadly. Is this too high and could cause damage? I wouldn't be adverse to opening it up and adding a resistor or two if need be. It's an Aliexpress one that uses a laptop power supply...

    MV1B1 Stuck in service mode

    I checked continuity with all the pins on the NEO-BUF and couldn't tell which ones exactly were connected, everything that seemed to be connected was a VCC pin. But maybe that's part of the problem itself. Replacing the NEO-BUF is way out of my depth, so if that is the solution then maybe it...

    MV1B1 Stuck in service mode

    Decided to check the pins on the dip bank, when a switch is on there is continuity between its two pins. No continuity when they're off. This seems to be perfectly normal behaviour, so I think I can be pretty confident that the issue does not lie in the dip bank. It could be a hardware fault...

    MV1B1 Stuck in service mode

    Seems to be getting 5.18V, which is the same as what my supergun's display is reading.

    No, all dip switches are off.

    MV1B1 Stuck in service mode

    Correct, no combinations of the dip switches made any difference. I do own a multimeter and have tried to check continuity between the pins on the dips and their destinations, but after looking at the dev wiki I'm not really sure where exactly they connect on the chips. I can tell that they're...

    MV1B1 Stuck in service mode

    It does, it was working fine in the past and still works fine when connected to a Pandora's Box. I also get the same issue with a different supergun, so I believe that the supergun's test button is not the issue.

    MV1B1 Stuck in service mode

    I recently got an MVS and supergun setup and it worked perfectly for a few days, but one morning it started having this issue and it hasn't worked properly ever since. Regardless of how I have the hard dips set, the console will briefly display "WORK RAM TEST" as if all the switches are enabled...
