ccfj1 is on a distinguished road
Once the ROM is corrupted then AFAIK the only way to "reset" it is to use the serial interface (on the main board) and the correct software to force a reload.

I do not have this software.

I do not know how to access the serial interface.

If a known good OS does not fix the problem then it is most likely either corrupted rom or one of the screen driver chips.

As these units are becoming older this type of problem is getting more and more common.

Other than the good OS disc or teh force reload (hold for 3minutes), then I dont know what else to try.

Cracking the OS9 operating system would help to use the serial interface and be able to access it, but as yet, no one has managed to do this.
