Intellabeam 700HX "startup loop" problem

Hello one and all,
I aquired a pair of Intellabeam 700's a few months back, and now one of them has decided to play up, just in time for me to need it!
Switched it off 6 days ago, when it was working fine, and now -
Turn it on, goes through startup proceure, lamp strikes fine, few more clicks and a high pitched whine,(from one of mirror motors, about 0.5 seconds, and it twitches) then it resets and starts the procedure again, without the lamp going out, repeats until switched off.
Any thoughts....?
(does it in DMX mode and self test mode)
Any help appreciated!

    The Intellabeam is notorious for connector failures on the power board. They may not look bad, but can arc internally, and lose contact.

    Having said that, I had a fixture that did exactly this a year or so ago . . . and it was a bad connector! The power in through the connector was adequate, right up until the lamp struck, and then enough voltage was lost or enough noise was induced from the arcing that the logic card reset, and the unit started the init cycle all over, just like yours.

    So, unplug and inspect everything on the power board that is connectorized, and in this case, most notably the AC power in and voltage select jumpers.

    I also suggest if you need to take the board out to replace one connector, that you replace them all with screw down barrier strips - they look just like the connectors, but don't come apart. I was having 1 or 2 failures a year due to the connectors, but have not had a single one since replacing them!
