Projector Beep Alerts

When a projector beeps on power up you have a couple things to be concerned about. If the projector is hot, the beeps can mean that it needs longer to cool down.

If you have not used the projector for several hours then it is cooled down. When cold, the beep alerts usually mean the blower fan bearing is restricted.

Clean the air filter and blow out the fan housing. You should just blow with your mouth because compressed air may damage your wiring connections.

If the projector is cleaned and you power it back up AND the beeps continue listen to the fan. The fan may need a little air pressure to help it start turning and then once it does the beeps should stop.

when does the lamp kick in right when it start or when the lamp light comes on

This varies by manufacturer and projector model. Without knowing the make and model of your projector it's hard to give you an accurate answer.

Lamps in Hitachi data projectors tend to come on almost immediately after starting the machine. Lamps on the older InFocus projectors took a bit longer before you'd see light coming through the lens.

If there is a short delay between the time you start your projector and when you first see light, I would not be concerned. Data projectors have to cycle on the same way they cycle off, meaning it's a process and sometimes seems like it is running slowly.

my nec vt48 projector gets hot and turns off. It gives off 3 beeps a few seconds after

This problem and the error beep codes indicate a lamp that needs to be replaced. The correct part number for the lamp is VT85LP. Basically the lamps are rated with a life expectancy of 2000 hours. At the 2001 lamp hour (3001 in eco-mode) the LCD projector will power on, but not display an image, due to the indicator requesting the lamp be replaced and the lamp hours reset (hold the help button on the remote for 10 seconds when powering it on).

A couple of things...

If the fan is not working, the lamp will not fire. If you have the owner's manual, it should indicate what the flashing lights mean. Check to make sure that the panels are seated properly. When you replaced the lamp, the outer cover was removed. If that is not seated back 100%, the unit will not work. There are a number of safety "checks" built into the unit to prevent damage and possibly fire as the lamps get really hot.

Check the items above and let us know your progress.

Reset Lamp Hours Timer

This works on a couple different Toshiba models -- might work on yours...

Make sure the main power switch is OFF. Hold the "ON", "MENU", and "INPUT" buttons at the same time and turn the main power switch on. Keep them held until the yellow power standby light comes on, then let go. It is done.
