I had extactly the same problem on one of my FZ's. It wasn't anything to do with the screen but before i could narrow it down i realised that the drive and disk controller seemed to be fried so i just junked the motherboard and sold the rest for spares.
If nobody wants the FZ i'd gladly take the floppy drive off your hands, its a bit tricky to get it out though.
In my experience disks from one FZ refuse to load on any other FZ, which is a bit odd
