I’m working on the acid damaged MPU on my Highspeed, I cleaned all the acid damage, removed U41, Socketed U41, checked all my work,
Everything seemed fine. Now I have an extra segment on The upper displays. Can somebody please help me in the right direction of which trace I need to look at to see why I’m getting an extra segment?
Or am I looking in the wrong area altogether?
I did have to cut off the 6821 to get the socket on and had to do some repair around the socket holes. Replaced with a new 6821.
