Question about Hitachi CP-S335 Multimedia Projector

CP-S335 popping noise when powering on

Just bought a new bulb. Checked it's installed right, watched a movie, everything fine. Turned the projector off. Wanted to watch another movie 10 minutes later turned back on, projector made "electrical?" raped popping noise. Unpluged everything, waited 10 minutes tried again, same noise. Third time turned it on and noise was gone. So What do you think?

Thanks for your time,

    The cooling down process occured to me as well. But the noise was spontanous, it should make the noise everytime the system is not cooled properly.

Hi Eva

A Projector does'nt like being switched on and off all the time , if you are going to watch a couple of movies - rather leave the machine running all the time - this will also help you to get more hours out of your lamp - and that's a promise.

As far as the noise is concerned - it is most probably just the machine that was not cooled down properly at that stage.

Why does it work for 10 min, then turns off?

U might have a thermal issue or better still, a false overheating signal being generated. If you have one of those small 8 inch desk fans, put it on full blast and give the unit the mother of all blow jobs while turned on to see if it shuts off. If it still shuts off something else is wrong. If it continues to work then ........................

I follow all the steps to reset the filter time and lamp time with a new bulb but it will not reset any ideas

This Projector is controlled by an internal microprocessor. Under certain exceptional circumstances, the projector may not operate correctly and the microprocessor will need to be reset. In such a case, please push the Restart switch by using a cocktail stick or similar and before turning on again, make the projector cool down at least 10 minutes without operating. Only push the Restart switch in these exceptional instances.

Infocus 4805 Lamp will not ignite after new bulb and reset.

it there is no high-pitched squeal when it starts up, the colorwheel needs replacing. the lamp won't light without it. the part is under $50, but installation is quite involved.
