more Cyber issues!!

I have a cyber hanging in a club that has been giving me what seems to be a common issue, it would boot up then run fine for a while then...... the bulb would go out and it would stop responding to dmx, then after 10 mins or so power down. Sometimes it was down for the night sometimes after a few mins it would reboot and run again, sometimes only for a few mins and other times for hours. Hell some nights it ran all night like a champ!! I've read all the post on here that seem to apply, and here is what I've done so far:

swapped out the 14 pin harness a few times--same

swapped out logic board a few times --- same

and yes the xlr connectors are locked

and today I pulled the power board resoldered the contacts, the reason for this is that if you bang on the light it starts back up making me think it's not a electric prob but something physical like a cold solder joint or component on the board. When I put it back in and everything worked fine....... however I do notice that one fan was not spinnig(one of the bottom ones) the light ran for about an hour when I noticed the lamp was out, it was running dmx fine. I was even able to re strike the lamp from the board, so I'm thinking it overheated. So I powered it off and back on, now here where I am lost? The all fans runs when the power is frist turned on it starts to home, stops for a sec the one fan then stops and it finishes homing and runs?

    Interestingly enough, I had an odd problem like this on an I-Beam a while back . . . one of the infamous "not if but when it will burn" connectors was just starting to go . . . everything worked absolutely fine when not struck, but when struck, it would just start going either nuts, or looping - IE strike, warm up, go out, home, rinse, lather, repeat . . .

    Amazing how the low current to run just the logic can pass through these dodgy connections OK sometimes, but when the lamp strikes, the drop is enough to make things go totally batty . . .

    Glad you found it, and even more glad that it was simple . . . .

    I find one of the best things to do when caring for older fixtures is to find out what the typical failures are, and make the first strike before they go. On the I-Beams, it's the PCB connectors . . . I used to fail 2 to 3 a year, and once they got replace with barrier strips, not another single failure . . . Can't say that I know of any failures in the Cyber that are as common as that to deal with (I-Beam pretty much taught HES what *NOT* to use . . . . ) but keep that in mind . . . with appropriate preemptive care, older fixtures can be almost as reliable as new stuff . . . . at least in my experience, and typically a heck of a lot easier to work on!
