Problem with HP-75C LCD display
Message #1 Posted by jbssm on 26 Jan 2008, 5:40 a.m.

Hi all,

I'm having a problem with an HP-75C calculator.

It works fine, but 2 vertical lines in the display don't show up. Is there anyway to fix this by opening the calculator? Any tips would be welcome.

Cheers to all, Jorge
