I just received in France a 41C I just bought from Canada on ebay (really great conditions, no scratches ... like anew one !)... But ...

When pressing ON, nothing happens.
After lots of trials, I finally found a way to turn it on : Master Clear (<-- + ON) several times. It looks strange no ?

Thanks for your help !

It sounds silly, but make sure all battery contacts are clean. Check all 4 of the spring contacts in the battery holder, plus all 4 of the gold contacts inside the battery bay (carefully). My orginal 41C (purchased early 1980) recently tortured me by refusing to turn-on. Like yours, the reset would sometimes work. After careful cleaning of contacts, all is back to normal.

Note that there has never been a battery leak in this machine, it appears it was just dust, plus age, plus a desire to toy with my emotions.
