HP 32S display screen dust
Message #1 Posted by jsrlnd on 28 Aug 2003, 10:16 p.m.

Does someone know how to remove the dust particles from the INSIDE of the display screen window on a HP 32S RPN? I own two of these with this problem.

Try blowing it with canned "air" from inside the battery compartment (about the only place to get the tube into the machine). Don't use shop compressor air. It always contains oil. Keep the can vertical and level so you dont blow the compressed liquid into the machine. It can leave marks on the display window.

Opening the calculator helps, but not enough to make it the first act. I would save that as the last resort.

You can try cutting the end of the air tube to make it fit into the seam on the sides of the calculator. Just make two diagonal cuts so it forms a v. Jam it in the side and give it a blast, just making sure the can is level as David Smith mentioned. It will take several shots from either side to get it all. Stubborn bits might need help from a small strip of stiff paper slid in through the side seam. Donít use anything sharp as the window material and LCD polarizer are soft material and scratch easily. Plastic coated paper (backing paper from double sided foam tape) works quite well for this as it slides in easily.
