Machinedrum SPS mk2 problem after changing battery

Hello guys I’m new here.

I’m looking for help with my machindrum.
Basically I changed battery by myself and from this time my machine after turning on is working few seconds and all buttons are switched off and display is just freezed.

I’ve done all resets and when making test mode everything is ok.

Already check battery voltage and power supply voltage.
All voltage seems to be correct.
Battery is about 3.10V and power cord 6.18V.

Anyone had maybe some similar issues??

Any chance that someone is able to help me please because I’m getting to be depressed.

Thank You and hopefully We Can find some solution.

Thank You so much for help by the way…:joy:

what I would do
remove the battery and wait 1min
put the battery again
if dont work do it again.
switching power supply can be very HF spurious
since I replaced it with a linear ps no more freeze crash ecc
