HP-97 with different problems Message #1 Posted by Johnny Bjoern Rasmussen on 23 Sept 2005, 4:16 p.m.
I'm trying to repair a friends HP-97 and need some help.
It sympthoms are:
1. Flashing display, specially the left most digits. The right most are still and not flashing.
2. Printer does not return carrige after being in the right most position. I suspect the reed switch or the magnet to switch the reed to be defective.
3. Only a few of the 'function'-keys work, eg. [sin] and [cos].
I have cleaned the pins cnnecting the PCBs and this helped preventing the calculator craching all the time. But I would like to be able to solve the above problems.
Thank you in advance!
