[HP48GX] Testing repaired keyboard
Hello,
I need advice to do the testing on a HP48GX. I have opened the calculator because the ON key wasn't working. So I placed under the flatpack a piece of rubbery scotch tape to be thick. But before closing the calculator I want to test if everything works. I connected the calculator to terminals of a 4.5V stack. Now as I can see if the PCB and flatpack makes contact? The negative pole is connected to the PCB only through the twists hooks? I attach same photos Tanks, fnas |
