RE: HP22S display working but with black elliptical stain
Hi,
just to report that I have finally repaired a HP22s and a HP32s displays following your recommendations (thanks!!). The process was absolutely satisfactory: -Open the calculator following one of the many tutorials available. -Remove the board, leaving the display accesible. -No not remove the display in any way. -Remove the two zebra connector stripes (the black band goes towards the display) -Peel the silvered adhesive plastic sheet that is adhered to the display. -Clean carefully the display glass, removing the glue stains (is there are). - This is the most critical issue: what can be used to replace the mate silver coated sheet? I suggest the mate side of home-use aluminium foil...I have tested many sources without optimum display tone. Remember : the mate side, not the bright. Carefully cut the proper size.. -Place this sheet in the display and use your finger to place it avoiding wrinkles!! - I find there is no need to glue the aluminium foil to the display... -Install the board back and test the calculator before putting the back side back. That's all! I have pictures, but high res...if you want, I can post them...after resizing. Hope it helps, Kind regards Ignacio |
