HP 41C Display

[Diego Diaz]

Hi,

HP-41C's are more likely of the "Coconut" type (squared display corners), so chances are that the display (LCD and driver PCB "sandwich") can be replaced.

A picture of the faulty display however would help to narrow the problem among several possible causes. Some of which do not require the replacement of the display.

In case it becomes necessary you'll need to find a suitable donor (coconut) 41 and someone skilled enough to do the job.

Details about the replacement procedure are described on the service manual, pages 3-4 to 3-5. Google for "HP41c service manual" (direct links to such info are not allowed in this forum).

Hope you find this information useful.

Best.

Diego.
