    I don't think it's even exiting power save. When I turn it on the power light comes on and there's a click from inside the monitor. After a few seconds the yellow power save light comes on and then I hear another click from inside the monitor. When I turn the Indigo on, it powers up and plays it's tune so I know that it's started but nothing changes on the monitor.

   I disconnected the video cable at the monitor and looked for sync on pin 3 and found that there was no sync* unless I started the Indigo with no monitor connected. (The sync was 63.something kHz). If I then connected the video cable to the monitor both the yellow power save and green power lights started blinking.

  *I don't think the lack of sync on pin 3 indicates a problem. This monitor is suppossed to Sync-on-Green. In fact, the lack of sync on 3 when I boot the computer with the monitor connected may well indicate that the computer recognizes that this monitor doesn't use a separate sync signal.

   The computer is definitely working. After trying these monitors I plugged the video cable into my usual monitor and everything worked exactly as it's supposed to.

   I was wondering, if I use a logic pulser and pulse the green input on the monitor will it generate random garbage on the screen? Any thoughts on that?
