Question about Bleeding HP-71B LCD

[Geoff Quickfall]

Hello Namir!

Hope all is well.

The bleed is a result of the LCD panel delaminating. Probably due to the adhesive joking the upper and lower surface degrading. Sadly It will progress but in a stable environment (no shocks or large temperature changes) it may last for years.

To access the LCD panel a set of heat stakes must be de-capped. The LCD panel is kept in place by a series of tabs. So the panel can easily be replaced, but the heat stakes are problematic.

Cheers and see you in the fall, Geoff
