LCD Projector Protection System / Izzuddin Aziz Shah Roduan and Mohd Jamhari Ismail Md Tokit

LCD projectors are used throughout the world in various different applications. Common failures seen in LCD projectors are the faulty lamps. LCD Projector Protection System is one of-a kind project that is designed to solve an intensive care problem while and after using the LCD projection. This project idea occurred in my mind after one of my lecturer was a in hurry, will not wait for the fan to stop rotating before switching off the LCD projector once finish teaching in the lecture room. A cooling fan is used to disperse the heat generated by an LCD projector and prevent it from overheating. The hot temperature is the major factor why the LCD projector is damaged if the user immediately turnoff the electricity supply socket after shutting down without waiting until the LCD projector cooling fan stop rotating. LCD Projector Protection System is implemented to protect the LCD projector lamp lifespan. This device starts operating when the system switch is pressed and the electricity will be supply and received at the LCD projector, at this time the indicator reads "Waiting for LCD ON" and the temperature is displayed for two minutes. If the LCD projector is not switched on, the electricity supply will be cut off automatically by the device. If the user continues using the LCD projector, during this time the indicator display reads "LCD Temp. System ON" and the current temperature for LCD projector will appear.
