RE: Dying HP41 Displays
Believe it or not, I am paying for taking time off to be at HHC2015. I have 25 ram in unknown condition but not 25c ram.
I will look further. Sounds like display drivers. I replaced Roger Hills LCD panel on his early 41c from 79. It displayed all @ also and after extensive trouble shooting a donor panel was needed. Cheers, geoff |
