HP 41CV Repairs



#2

Morning

I am having an old HP 41CV which need some repairs.The problem is that if I put in new batteries,it only turns on once and the batteries are flat in an eye's wink.The batteries are very hot when you touch them and they do not have power any more.Any suggestion how this can be fixed is appreciated.

Kind Regards
William Mabotja

Last I heard, the latter was too backlogged to take any new work, perhaps because he's trying to retire. The first one is taking up the slack.

Hi,

I think, in this case, that there is at least one diode (or a capacitor) in short. Depending your skills in "electronics", you may be able to repair by yourself... Otherwise, you can follow Garth Wilson's sugestion.

Good luck

This without a doubt , more likely to be a cap
