Amiga Hardware Issues and discussion / Re: Annoying A1200 screen flicker / wavy on disk access

I've suspected it could actually be the floppy drive drawing too much current on motor start. Its not a shielding problem, its the 5V rail dipping and the monitor loses sync, I can see it on my scope. It happens even with all shielding installed. I've tried different power supplies so its not the supply. I've tried a different video cable. This is a bare bones mainboard no accelerator.
Panasonic Drives are known to require a re-cap. Could be a failing cap putting out too much noise on the motor. Worth a try.
