PMG4 1.25ghz, Radeon 9000. Using 21in analogue monitor which was working
fine.
Powered down my Mac yesterday to give it an internal dusting. None of the
PCI/AGP cards were touched/bumped etc. Plugged everything back in. Now my
21in monitor (after the boot sequence) gives me a "no signal" error. I can
use a 15in monitor no problem and the 21in seems fine during the boot
sequence (you can see the OSX booting but once the desktop comes up I get no
signal).
As a result I am using an old 15in analog. I would like my 21in back on. Any
ideas?
Reset your logic board. Unplug from the mains, leave for 30 secs, then open
the side and press the logic board reset button, usually near the battery
depending on the model. Might make it come good :) Are you running MacOS
X, or 9.22? I've seen this method fix similar problems on 9.x machines.

OSX.3- I couldn't see the reset button but I did do a PRAM reset on startup.
Will try again and cross my fingers, say some hail marry's and burn some
incense at the same time- it's like reliving the old SCSI demon days!
