Will not turn on. power light is orange

Many projectors will not turn on, or will turn on and immediately shut down, when the lamp needs replacing. How long has the projector been in use? Most lamps say they're good for up to 2000 hours, but in my experience they're only good for 1400 to 1500 hours. Also, check that the electrical cord is attached tight.

Nec lt380 changed lamp for new one still doesnt

If the unit is powering up but the lamp is not igniting, most likely there is a problem with the ballast.(Ballast is the circuit that starts and then maintains lamp current) When starting the projector, it is sometimes possible to look directly into the lens and see small "lightning" flashes. This is the high voltage ignition current trying to start an electrical arc in the lamp. You can also hear a "clicking" sound--same thing. If the ballast is defective, the unit must be repaired at a facility--send it in directly--not through a store. If the unit is totally dead(no lights at all), there usually is a main fuse located near the power cord(inside the unit) that blows. If you've never had tech training, don't attempt to open the unit--it is very easy to accidentally damage components unless you know exactly how to remove the top cover.

NEC projector M322X indicates light but cannot turn on

Based on the information provided, it is possible that there may be an issue with the projector's power button or internal components. It is recommended to try the following troubleshooting steps: 1. Check the power source: Ensure that the projector is properly plugged into a working power outlet and that the outlet itself is functioning correctly. 2. Reset the projector: Some projectors have a reset button or option in the settings menu. Try resetting the projector to see if this resolves the issue. 3. Check for internal issues: If the above steps do not work, there may be an issue with the projector's internal components. It is recommended to contact a professional technician or the manufacturer for further assistance. In summary, if a NEC projector indicates light when plugged into a power source but does not turn on when the power button is pressed, it may be due to issues with the power source, internal components, or other factors. Troubleshooting steps such as checking the power source and resetting the projector may help resolve the issue, but professional assistance may be required if these steps do not work.

I have a NEC PA521U Projector Red Lamp Light and will not turn on

I suspect the ballast (supply for the HID lamp) has failed due to an expired lamp. Probably not ecconomic to repair.
