C128D troubleshooting help needed - diagonal stripes on 40col
Posted: Thu May 18, 2017 7:33 pm
So I got my C128D package today, with the main unit, keyboard, three utility disks, 1351 mouse, A/V cable and 1802 monitor.
I assembled the whole thing, powered it up in 40col mode (no 80col screen) and it worked well for about ten minutes or so. I messed around 128 mode, went into 64 mode, went into CP/M mode using the provided floppy, returned to 128 mode. Then I powered everything off, plugged the mouse into the closer port, powered it on... and got greeted with this.
The chroma is gone and the entire image looks... out of sync.
Did I just brick it? Is it a dead IC like an 8701? It worked for a good ten minutes, please tell me there's something I can do besides despair.
