I am now a bit reluctant to order an other one...

Did you check the usual suspects, like battery contacts and power switch?
Also check the keyboard as the keys can easily cause issues.

Yes I did, I opened the calculator and check with a voltmeter that the current was reaching the PCB. I also tried with a regulated power supply. For the power switch I tried by-passing it again directly on the PCB.

Did not even had time to try to enter a first program...
