Hi Kevin, I solved my problem with the precious help of Gary from Elecrat and Bob, G3VVT who had a similar problem and we sloved it the same way :-)
I forgot to solder pin 1 on U1. The best way should be to desolder the 6 front LCD pins, move the LCD gently to the back and desolder the 4 LCD backlight pins. I was afraid to break something so I decided to cut the corner of U1 support to have access to Pin 1. Then I soldered it from the upper side. And it works since yesterday night where I did the firts tests that are all Ok. I'm going on Part II now :-) Thanks everyone for your help, Best 73, Philippe f8bxi Le mar 29/06/2004 à 12:14, Kevin B.
