SE/30 with flickering brightness
Posted by: benlong200 on 2020-09-04 04:45:15
The screen on my SE/30 is flickering but I’m not sure that what it’s doing is what other people here call flicker. There are no lines appearing, the brightness just varies, flashing brighter and dimmer as the machine sits there. Any ideas?

Bad solder joint on J1 ?

The brightness pot can go bad as well, I have an analog board that does the same until I wiggle the pot a bit. After that it will be fine for some time until I pull it out of storage for the next time.
