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.
