HP48S strange behavior

[BartDB]

Hi,

The display lifts out of the metal frame. As I recall, it is stuck in with some double sided tape on the top and bottom of the display but with some careful pushing and prying it comes loose.

As you said you can wash with the display out of the water (but remove the zebra strips to prevent them falling into the water).

Regards

Got the the calculator almost dismantled. I admit it's been a difficult work. Mine is one of those older ones from Singapore, as far as I can see engraved on the back cover. Iphones are much easier to dismantle!

I have also removed the PCB. What a piece of art, my lord! All circuits there, are perfect. No problem at all in there.

So my only possible try is that "wash and dry" process for the keyboard. But I haven't find the way to remove the display.

How do you remove the display? Do you remove it together with the metallic frame? Or you someway disconnect the display itself? How?

If I'm able to remove the display, then I'll sink the complete keyboard into water. If not, I will maintain the display out of the water, as Geoff Quickfall explains.

Thanks for all your help!
