CP745ES How do you reset the lamp hours?


You have to enter the factory menu by pressing a sequence of buttons when the projector is on: Power > Auto > Menu. I remember it by the female name Pam.

My light comes on dim then goes off an the thing still run a fan and look like it on??? please help


it's either the lamp or the ballast. check the inside of the lamp. if you have bulges, black spots, flaking or fogging, replace the lamp. if the lamp is ok, replace the ballast.

Boxlight cd-850m won't turn on


You must reset the lamp timer after you replace the lamp before the unit will turn on. Do this:
Power on the unit. On the projector's keypad, hold down the the two volume keys simultaneously for 10 seconds. At that point the LED will turn green. Now you can turn on the unit again and it should work.

Lamp shuts down after startup


it is the power supply/ballast. when you first turn it on, the caps on the ps/bal charge then discharge when the lamp is to strike. if the caps are dried out (from excessive heat), it takes a while to build a charge. so the power drain from striking the lamp brings the ps/bal into shutdown. after you try again, the caps are now up to full power and everything is fine. but every time you unplug it, you'll have the same problem. replace the power supply and ballast.
