Re: [Elecraft] #5956 problem - solved
Bob, Unless the polarizing strip is flexible as well as the protective strip, I'd have to say no. Any other ideas in regards to my viewing problem? I could try cutting away at the IC socket and resoldering the pins from the back to see if that helps any.

I dug the old strip out of the trash, cleaned it off and stuck it back on so I could continue building--it's still there working just fine.

If you suspect the LCD pins, they can be soldered from the top side of the board which often provides a better connection since it is difficult to properly heat the pins with no projection from the bottom of the board. 73, Don W3FPR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] #5956 problem
Check your display installation and the display driver (the big chip on the back) installation. Make sure there were no bent pins when you pushed that thing in. I know I was sweating bullets during that. I assume all your other resistance checks on that chip were fine? Did you check them on the pin of the chip, or on the associated pin on the back of the board? David Wilburn [EMAIL PROTECTED] Matthew D.
