Repair your projector for extended usage.
Making minor repairs and maintenance can extend the life of your Sharp projector. Sharp is an innovative consumer electronics company that makes video projectors for both business and home use. They are built with high-quality components and are easy to use. The projectors are also designed for ease of use and the ability for internal components to be accessed for repair. Most problems such as bulb issues, power problems and connectivity can be repaired without a technician.
Instructions
1. Change the projector bulb to improve video quality. Sharp projection bulbs have a life cycle and the projector normally notifies users when the bulb's life cycle is low. When necessary, it needs to be replaced by turning off the projector and unplugging it from the power outlet. Remove the lamp cover with a screwdriver to access the lamp unit. Remove the lamp unit from the projector housing and replace it with the new bulb housing. Replace the lamp cover and power on the unit to ensure it works correctly. Reset the lamp timer to keep the projector in sync with the bulb's life cycle.
2. Change the selected input if there is no picture or the projector will not power on. Verify that the lamp unit cover is securely connected to the projector and that the bulb's life cycle is not expired. Verify that the video format and resolution being sent can be processed by the projector.
3. Adjust the focus and verify that the projector is within the right distance of the screen. Move the projector closer to the screen, if possible--and, depending on the model, adjust the "Digital Noise Reduction" setting to improve the video quality. Clean the projector lens if it is smudged or dirty to ensure a sharper picture.
4. Make sure the projector bulb is operational. An expired bulb will cause the projector not to power on. Make sure that the power outlet is active and any surge protectors being used are powered on. If the projector is kept in an enclosed area, it may also have overheated. Reset the projector by unplugging the projector pressing the power button then plugging it back into the outlet.
