New lamp turns on flashes 7 times


Just a thought...you *might* have a bad ballast in addition to that defective power supply.That flashing could be the ballast trying to ignite the lamp. A lamp is just like an enclosed welder's arc. The ballast generates a high-voltage spark to initially start the lamp, then low voltage with high current keeps it burning. If you look into the lens and see "lightning" flashes but no lamp ignition, that's what's happening. The ballast could've been damaged by the defective supply. Also, try a known-good lamp...just to rule out a defective new one--in the shop, we kept all old working lamps as testers.
