I have never seen an iMac CRT failure, other than from being dropped. The CRT is the cathode ray tube, often abbreviated to tube. The chunk of glass you view. I have seen lots of failures relating to the iMacs monitor circuitry. Very common with the tray loading rev a - d is an arcing noise, image shaking, then eventual failure, no image. Sometimes the power light will stay on, sometimes the iMac will completely shut off. This is failure of the analogue board, and with all I've investigated caused by flyback transformer failure. If you don't back up regular, now's the time to start. Steve Bell -- The iMac List is sponsored by <http://lowendmac.com/> and...
