Support is not granted for many years now.
Try the next tricks : Most of the presumed dead 41's, unless PCB corrupted, tend to come back to life. ▼

Thank's for your answers (Thibaut / Vieira). The problem, more explained, is on the thin panel that connects batery pack with the main board. I forgot bateries on machine for long time and this panel has been damaged. I have clean it (more or less) and I think that may be damaged inside too. Thanks for ideas

Then you're in trouble. If you can't clean the contacts and if they are damaged, well this can be hermfull enough to have the calc definitely damaged. But there is still a solution. 41C's are quite cheap on ebay or on the classified's ads. You could buy one and easily replace the battery contacts/module contacts board. No soldering at all is needed, only good contacts with the PCB and this board. And maybe you'lle get some modules with the calc and some manuals... always something good in a bad news !

Hi; Complementing Thibaut's answer (maybe, there's still a chance...), I'm continuing the thread from here :-) Try this and this links and read the posts. I believe they will give you an idea of what to do. If you believe a technician will still be needed, print the posts and show him. And if you still need help, post again. Cheers. ▼

The reverse polarity trick will not help you, the 41C (at least mine) has a series diode which prevents reversed batteries to feed the CPU board and the power supply chip there placed. The reversed voltage will reach any modules or peripherals you have plugged into the back ports, possibly damaging them; so it is strongly perferrable to unplug any accessory before such testing. Good luck!

Hi; Thibaut's guidelines are essential at this point. In fact, describing briefly the problem(s) might help a lot. And another very important question: as you are looking for authorized support, would you be able to fix the calculator yourself? I mean, you did not mention your skills as technician; should we consider you know how to proceed? Forgive-me if you are an expert, I just want to know if Thibaut's wisdom guidelines will be effective. Cheers. |
