Hi all,
i would like to have an 'expert' opinion on a dead 1987 built HP-41CV. i don't know how long it has been stored without batteries (must be years!). However after inserting new batteries, i can't get that nut awake. I've already tried the usual measures (as discussed here in the forum) to reanimate it, but had no success. power supply gives just below 5V after inserting the batteries and 6.35V after ON has been pressed and released ( measured on the cap next to the choke).
any pathological hints about it? What are the usual suspects? I have scope, voltmeter, etc., so there is no prob to do measuring on the internals.
tia for your help!
Hans
