I have a Mac Plus that I bought new that I am trying to get operational again. When it finally became unusable, the screen would go to a thin vertical line and sometimes it would work again if I tapped the case. This issue would happen right away upon turning the Plus on. I resoldered some of the joints (L2, C1, J1) on the analog board and it seems to be better, but there is no start-up bong when I turn on the machine. The screen appears normal with the flashing floppy icon. I haven't been able to do enough testing yet to see if the resoldering has fixed the issue after it has been warmed up for a while. What is the cause of no start-up bong?
I also have a spare logic board that operates weird. At start-up, the screen is the size of a postage stamp, tightly surrounding a frozen floppy icon. The rest of the screen is dark. I haven't checked to see if it can boot, but I figure this is a significant failure. I have tested this logic board with a known good analog board and the board that I described above. Can this logic board be repaired? Thanks, tt -- Compact Macs is sponsored by <http://lowendmac.com/>.
