I've been having a recurring screen display issue on my AFS3500EE which I thought I had fixed by properly re-seating a connector, but it has re-appeared the next day without any obvious reason.
The screen powers up white all over (either on main-buss or on back-up battery) and then slowly changes over time, usually with black vertical lines showing, then with a "tunnel-vision" effect where black grows towards the centre of the screen. Occasionally the screen will show fast-changing garbage as in the video available here https://www.dropbox.com/s/a808cy04u9...O0052.mp4?dl=0. The main CPU is working fine, as I still get audio warnings (low oil temp, etc). My feeling is that it's something tolerance-related in the display module that may be affected by cooler mornings here in the UK (about 5 deg C at moment). New BR1225 installed but no change. Buss and backup battery voltages appear fine.
Any ideas?
Thanks
Tim
