still working on my allied crack shot, and will be for quite a while. i was running it ,and one of the projector bulbs popped, the glass shattering . maybe it was damaged, but i think it was from heat. they generate a lot of heat, and the only cooling is louvers on one side of the lamp box, and the hole where the light comes out, about the size of a nickle. no fans. there are 5 projectors .
i put black tape around the edges of the lamp boxes. when they folded the sheet metal, there were gaps, and light bleeding thru looks like crap on the screen. i also put tape around the edge of the bulb holder, light bleeds out of there too. 100% improvement in the images. could closing up the gaps cause an over heating condition?
i have to add, i disconneted the timer motor, so i wouldnt have to keep starting the game while testing it.. maybe i ran it too long. it didnt seem long and a kid with a lot of quarters could have run it just as hard.
it uses 150 watt 120 volt T10 4-Pin (G17q) Base 3,100K CAR Overhead Projector / Stage / Studio GE Light Bulb .
any thoughts or experiences like this?
thanks
mike
