black screen after cleaning

crwdns2934249:0crwdne2934249:0:

I disassembled and cleaned the dust from a WORKING G4 iMac 700 Mhz with 15" monitor.  Now I get a black screen on startup.  After the startup chime a pure tone sounds three times.  Then the monitor light blinks a repeating pattern:  once long, 3 times medium and 1 brief flash.

I re-opened up the case and found no loose connections.  This is not a backlight problem.

The tones and flashes must mean something.  Anybody?
