RE: HP32E Repairing

Did you manage to progress on this display issue?

I'm planing to acquire my first Spice machine and considering the high prices asked for "untested" ad "sold as is" items, I'm afraid of getting one specimen with exactly the same issues.

As a side note, I found a picture of a "modified" HP-32E machine using 3 x AA battery cells for a total of 4.5Volt.

Cosmetically considerations aside, for a machine designed to operate with 2.5VDC at most, applying 4.5VDC is kind of power supply stressing, and I'm not sure about the LED operation.
Do you know if the LED module power lines are coming directly from th battery supply bypassing the regulated dc-dc power supply?

Here and here.
