Question about NEC (50019497) Projector Lamp for VT440, VT54

VT440K orange power flashing red status light, overheated.

I have a vt440k and the power light is orange and the status light is flashing red. Its strange the manual says there are 4 , 8, 12 second intervals that it can flash but it seems to do 6. 4 indicates an overheat and 8 indicates a fan problem.

I can see the fan on the front and side are spinning because there is air coming in and out. It overheated while I left it on for around 1-2 hours, I left the room for 10 minutes and came back and it had turned itself off. There is no way to see if the fans are working because it won't let you turn it on with the filters off.

When I turn it on first it goes to green power light. Then it goes to green and orange flashing. Then to red power flashing with orange status before it settles on the red power and orange flashing (6 seconds). I've had it working fine for about 20days. It was a recent purchaes on ebay. The bulb is brand new off amazon but it looks like the casing has melted very slightly on the bottom during the overheat. Bulb looks fine though. Tried a different bulb to no avail (old bulb).

Any ideas?

My NEC vt 595 was working fine last night and today i went to turn it on the status and power light started flashing red and orange and there is no picture


if Power is flashing orange - then it's cooling down

if Status is flashing red - then there are 4 flash combinations.
1 cycle (0.5sec On, 2.5sec Off) lamp cover or housing error
2 cycle (0.5sec On, 0.5sec Off) temperature error
4 cycle (0.5sec On, 0.5sec Off) fan(s) error
6 cycle (0.5sec On, 0.5sec Off) lamp error

Which is your condition?

Turn on the projector the power light flashes green with status as green then it goes to a flashing orange light


there should be a status for the lamp light; check to see if this one turns red. If it does count the consecutive blinks if it is 6 then replace the lamp

Continuous alternating one green and three flashing red battery


note.gif NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer. Check the battery status light — If the battery status light flashes orange or is a steady orange the battery charge is low or depleted. Connect the computer to an electrical outlet.
If the battery status light flashes green and orange, the battery is too hot to charge. Shut down the computer, disconnect the computer from the electrical outlet, and then let the battery and computer cool to room temperature.
If the battery status light rapidly flashes orange, the battery may be defective. Contact Dell _I found this on : http://support.dell.com/support/edocs/systems/latd820/en/ug/index.htm Hope this helps and good luck. if i "fixed ya" please rate me. thanks-jmattes

Power light flashin orange, status light flashing red on WT610 NEC


if the status light is flashing .5 seconds on and 2.5 seconds off - you need to replace the lamp cover correctly.
if the status light is flashing .5 seconds on and .5 seconds off in 2 - 6 cycles the error is: 2 cycles - the projector is overheated. Move the projector to a cooler location, or/and remove dust in the light path. 3 cycles - the power unit is not working correctly. 4 cycles - the fans are not working correctly 5 cycles - lamp fails to light. Wait a full minute and then turn on again.
