Strike issues with StudioSpot 575

Hi,

I have some older (99-01 era) Studios Spot 575s.
One of them just today started having lamp strike issues. After powerup and homing, the display says STRK for a few seconds, then goes black. There is no "strike" sound, and the lamp remains dead cold. after about 30-60 seconds I get a "LITE TOUT" error. I've replaced the lamp with a new one, but I know both lamps work fine, I tested in other SS fixtures. This fixture was working fine last I turned it on about a week ago. Any thoughts on where I should start my troubleshooting?

Thanks,

  • I bet it is the lamp power supply, They do go out, especially if they have been connected to a dimmer, and yes a dimmer is still a dimmer even if it is set to Full, they are still recieving a square wave. I would meter the power comming from the lamp power supply into the ignitor. You should be seeing around 400V. Be careful not to shock yourself, it hurts a lot. I have a scar on my hand from touching the wrong part of an x-spot by accident, needless to say the lamp powersupply was good.

    As a quick refresher, dont you meter the black leg and the white leg of the lamp power supply independtly, and the chasis is the ground, and dont you measure in DC? I cannot remember its been a while.
