HP-41C Troubleshooting

[Diego Diaz]

Hi,

As previously stated, a detailed step by step sequence of the symptoms' appearance is a good starting point to diagnose any faulty device.

In the HP-41C case (apart from removing anything connected to the I/O ports) should begin with a [MEMORY LOST] ;-)

Anyhow, in most cases, with this model (assumed Full-Nut), weird behaviours are related to cracked screw post(s) and/or internal corrosion due to battery leakage.

Pictures are more than welcome in case you decided to open the unit.

Best regards.

Diego.
