CPC 464 green screen on startup
« on: 21:53, 26 June 21 »
Hello all


I am trying a CPC 464 that i found and when powering up only presents a green tinted screen.



I checked:
- 5V supply (working)
- Clock Signal (16MHz on the crystal and IC125 as well as the gate array Pin 24) confirmed


I am not quite sure where to start searching. When powering up, it also takes quite a while until my OSSC syncs on a signal and displays this picture.


Any help would be great

Thank you
Sebastian
