Dear colleagues,

I've got snapon MODIS used item, with non-working Y-N-Thumb buttons. They are completely dead.

I can work with the device with mouse in USB and using virtual keyboard, but it is PITA.

I disassembled the device, got to buttons, cleaned them, reassembled - no change. All dead.

Device(MODIS) itself works OK. Then I checked power on Y-N-Thumb button circuit board and it receives +5v. Cable tested out OK as well.

Are there any known workarounds or what component gets bad there? Before I will try to figure it out, I would like to ask here, may be someone can point me to the right direction.

TIA
