My plv-z4 projector makes a crackling noise when i plug it in

SOURCE: sanyo plv z4 shuts down

call sanyo tech department and they will help you increase the fan speed to cool the unit. This is done with the remote so it was pretty easy. Make sure your filters are very clean first (use compressed air or a co2 canister. Have not had a problem since, my units run on average 8 hours a night and have not shut down.

Yes, it is the projector.
Take the filter out and vaccum it, take the lamp out and use compressed air to clean the dust away.
Be carefull witt the air thoug! keep it a bit away from the projector when u cleand the dust away, to close and you can make big mamages inside it.
And, remeber to keep the filter as cleas as possible, i clean min every 2,5-3 monthes.

Good luck

You will need to reset your lamp timer.
