I have a studio color 575, circa 99 i think. Anyways it will decided to on its own to home itself. After it completes that the lamp will douse itself. Anyone have any clue as to why it does this. It usualy occurs after the lamp has been on for a few hours. Thanks. Seth Thiesen
Dont have then entire story? what other information would you like? It works just fine in sound check and then in the middle of the service, after it has been on for a few hours, it will just start going through the homing sequence and when it is done it the lamp isnt on. The fixture still moves and everything like it should, but no light.
sounds like a ballast issue to me....either that or something is interrupting your power momentarily.....are you powering the fixture from a dimmer by chance?
The fixture is running off 208V constant power. No dimmer, no relay. There are a number of other fixtures running off the same source so I don't think it is a power source issue. It is something inside the light.
Is it possible that the homing is being caused by a faulty profile or personality on the console? What console are you running it on? If the console is sending a "reset" command when it should be sending, let's say, "strobe," it may be doing that for you. Just another thought. Try readdressing another fixture to the same address and see if the problem repeats with then both fixtures.
The reason that once it resets that the lamp turns off is because of what was stated above: no hot-restrike. When the fixture homes, it automatically tries to strike, and thus strikes a hot lamp and upsets the lamp.
The lamp should be on after a home. I have homed lights many times in the middle of a show, after a color wheel or something gets out of place, and the lamp is always on after the home. I am using a Jands Vista, and I don't think the console is sending out a home command becuase it does it random times, it isnt the same time every time. It is really more based on how long the fixture has been on. I think it has something to do with heat.
Id re-address just to eliminate the control factor from the timeline of events. Then go from there. I do kinda smell a bad ballast or a loose wire perhaps.
