Question about ViewSonic PJ458D DLP Projector Multimedia Projector
My ViewSonic PJ458D turn on but in 15 sec turn off, and i got some light but after 15 go off again.
This is known as 'cycling' and is common with mercury-vapor bulbs nearing end-of-life. When the bulb first starts, it glows dimly and grows in brillance. As the light grows, the pressure and temperature of the bulb also grows--increasing power demand. After a short while, the demand exceeds the ballast limit and the bulb extenguishes until the temperature (and pressure) drop again. Then, the cycle starts over. Bottom line: you need a new bulb (or, the correct bulb).
