If your Meiko projector won't turn on, there could be a variety of problems. Here are some possible solutions:

1. Check that the power plug and power cord are securely connected. Make sure the plug is plugged into the electrical outlet and check the power cord for damage or cracks.

2. Check whether the power switch is turned on. Look for the power switch on the projector and make sure it is on.

3. Check whether the light bulb is broken. If the lamp has burned out, the projector will not start. You can confirm if the bulb needs to be replaced by looking at the bulb indicator light.

4. Check whether the projector fan is working properly. If the fan is not working properly, the projector may stop operating. You can check if your projector's fan is clogged or faulty and replace or clean it if needed.

5. Reset the projector. Some projectors may require a reset to start up properly. You can follow the instructions in the user manual or contact customer service for assistance.

In summary, if your Megaprojector won't start, first identify the problem and try to take the appropriate solution. If you are unable to resolve the issue, please contact Customer Service for assistance.
