Does it work OK on "battery" only, Hassan? smile

And ... what is the condition of the battery?

What happens if you remove the battery and try again on mains power? think

Well, you could try the unit with a known good battery ... but it's beginning to sound like the problem could be on the battery charger board (AC Charger Assembly) or the Battery Interconnect board. I would suspect the former (which is, I believe, basically a SMPS). frown

I don't have any of these units to look at (nor indeed, a circuit diagram), Hassan ... but if you have other units available, you may need to do a bit of board swapping now, I reckon.

Maybe someone else on here has recent experience on these defibs (and would like to chime in)? think
