I read the OLD six-page thread on these. We had a failure three days ago...blinking "fault" lamp. About 4 hours after a heavy set, lots of volume, swinging light fixtures, full drum kit with 8 mics, bass, and acoustic with one vocal.
The failed amp was only for our big sub-woofers, left and right.
We did the normal stuff...unplugged inputs and outputs, let it sit for 2 full days....still a blinking fault lamp.
I went through the troubleshooting comments. Reset button did no good.
The local shop said these were a bear to get apart, wanted three hundred bucks to diagnose it.
Bought a new Crown, brought this into my shop...10 minutes and the top was off, and main board out.
And that was stopping to re-light the stogie.
I cold ohmed all the power transistors, the heat sensors, all the bits....all matched resistance readings, good channel to bad channel.
Scratched head.
Put the main board back in, left the input stage plate off.
Powered it up. Two clicks, no blink.
Okay, shut down, put the input plate in, powered up, two clicks, no blink.
Let it burn in for an hour....no blink.
I'm about ready to tag it, place it back in service and see if it fails.
My guess is, undo all the plugs, plugged them back in, and any issues were in a poor plug connection?
CE1000's went into service with the new overhead array 9-10 years ago.
Anybody run into this before?
