Re: HP-41c display problem Message #4 Posted by Ignacio Sánchez Reig on 4 Sept 2013, 3:50 a.m., in response to message #2 by Randy
many thanks for your detailed answer.
But:
- I have connected only three lines in the top left side of the display (leaving free the most left one). The continuity in the connections has been tested and is OK.
- The board already implements the suggested 470 pF capacitor. If it helps, I can see in the reverse of the board the following: 01303L; 00041-60001; J-1935.
- I have tested the calculator with two 41c boards with the same 470 pF capacitor, so the capacitor is fine.
-I still makes the same: it displays perfectly while you keep pressing the key; it gets blank when you release the key...I am getting crazy!!
Many thanks again in advance.
Regards,
Ignacio
