It’s better to go with a certified NEC projector repair supplier like eReplacements because NEC projectors are very sensitive to fluctuations or power issues. So if you find your projector not working, the first thing you should do is to check if there is a power outage in your area or a problem with your power source. However, when you find there is no problem with the power source and the monitor is still not working, then the next step would be to check if the projector lamp is functioning or not. If it’s not, then you have to replace the projector lamp. If the lamp is fine, then the issue might be with the projector’s internal bulb, which usually happens if the projector is dropped or has experienced some sort of physical damage. In that case, you will have to get your projector repaired by a professional service center.
