I just shipped a Mac Classic overseas. When it got there, they plugged it into
a trasformer and here is what happened: The mac powers on with its
normal beep. The hard drive starts spinning and makes its normal starup noises.
HERE IS THE PROBLEM: The screen is completely blank! Not even a flash of
light! Nothing at all!
What could have gone wrong?
Any help would be greatly appreciated.

They just gave me a new analog board. But the Classic doesn't have a brightness knob. Maybe the connector to the CRT has come off in shipment: doesn't happen often but I have seen that also.

Or the tube could have broken. I've seen that too. You need to open the machine to check for these possiblities. -- Philip Machanick philip@pescadero.stanford.edu

Sounds familiar. I have had six classics now that have required the re-seating of the yoke connection to the tube. Its a simple procedure to fix, but when you have inxs of 10 macs a day to get through., it becomes a bit of a hassel. So try that one if all else fails. steve h
