The status light is on our NEC MT850 and the bulb looks fine. What other problems could it be?


1,Check the fans ,whether each fan is running,when you turn on the projector
2,if the fans run, then ,check the lamp or lamp ballast
turn on the projector ,at the same time ,if you can hear a continuous beep beep sound (the ballast igniting the lamp)
means the lamp may be fault,and other parts is working well

I have an NEC VT470. The projector shut down after the lamp finished. When I replaced the lamp and pressed the start button, the projector does not come back on.


Some of the NEC units have a standby status when the lamplife has exceeded its safe limit, the unit I had needed the off button pressing for up to 20 seconds to reset the lamplife and allow the unit to be switched back on. There should be info for this in your manual.

Good luck

New lamp turns on flashes 7 times


Just a thought...you *might* have a bad ballast in addition to that defective power supply.That flashing could be the ballast trying to ignite the lamp. A lamp is just like an enclosed welder's arc. The ballast generates a high-voltage spark to initially start the lamp, then low voltage with high current keeps it burning. If you look into the lens and see "lightning" flashes but no lamp ignition, that's what's happening. The ballast could've been damaged by the defective supply. Also, try a known-good lamp...just to rule out a defective new one--in the shop, we kept all old working lamps as testers.

NEC projector LT220 - replaced bulb, works for 1.5 hrs then switches itself off


Hi Matt

There might be a couple of reasons for this problem.

Best is to start with the lamp - return the lamp to whoever you bought it from and insist on a another new one.

If the problem still occurs you should rather take the unit to a repairer - because it could be the Mainboard or the Ballast ( lamp's powersupply ) that is faulty and will need replacement or repair.

Check if your unit is under warranty - because the replacement of a Mainboard is quite expensive.
