Are you able to power on the projector? (have at least one LED ON?) 2. The Colour Wheel is spinning? 3. You have OEM or Original Lamp inside? Try with original one (with proof) first! Are OEM Lamps really Original? When purchasing lamps, it is important to read the fine print. More often than not, an OEM lamp simply means that the lamp is manufactured by one of the 6 or so major manufacturers, and is not actually an original lamp. It is important that you evaluate your needs: if projector uptime is critical, under no circumstances should you use a cheap OEM bulb from an unknown source. Most critically, these cheap lamps are known to cause power fluctuations, leading to damaged PCB components and blown ballasts. Ballast working principle: Ignition failure can be detected as the electronic ballast is in open-circuit or hot lamp state, while current is small. The ballast attempts to ignite the lamp for three times, which interval is 10 minutes. If the lamp is in hot-lamp state, it can be cooled down during the interval and can be ignited normally. If the lamp is in open-circuit state, it can not be ignited during the intervals. The microprocessor stops the output of the ballast. Moreover, Short-circuit protection can be detected by the lamp voltage.
