Canon LV-7210 Troubleshooting

The projector will not respond or show any sign of powering up.

Check to see if the power cord is plugged into the power outlet and the correct port on the projector. Also check power cord’s overall condition. If it is worn, replacing it could solve the issue. Additionally, check to make sure all other wires are connected to the correct ports.

The projector could have accumulated dust over time. If so, try to get as much dust out as possible. Clean the vents and filters of the projector, also check the lamp for any dust build up. Clean the lamp surrounding area if necessary.

The projector overheating can cause power loss. Make sure the projector is in a well ventilated room and not placed directly in sunlight. Make sure the vents are not blocked and that the fan is free from any jams. If these steps do not solve the issue, it is likely that the fan is broken. The fan would then need to be replaced to ensure the projector cools properly to remain at the proper operating temperature.

Image does not display as desired when projected onto the screen.

The image could be out of focus because the lens is scratched or damaged. Check to make sure the focus settings on the projector and computer are correct.

Disconnect the AC power cord, and wipe the lens with a cleaning cloth with a little bit of lens cleaner. Be careful about the cleaner you use, harsh chemicals will damage the lens. You can also replace the lens cover if the lens cannot be cleaned by hand.

Check if all the wires are properly connected and secure. Securing a wire means that the wire is locked in place allowing the minimum amount of movement. Make sure it is completely connected to the projector. Check to see if the video wire is the issue by using a different one.

You have trouble hearing sounds from the projector, or no sound is emitted at all.

Make sure that the audio cable is connected.

Make sure the volume on the projector is on. Make sure the settings on your computer are set to output the sound though the projector speakers and not through the computer. If these steps don’t solve the problem, the speaker on the projector might be faulty which means it will need to be replaced.

Make sure the volume is at the appropriate level and not muted on the projector, your computer, or the external speaker. Make sure the speaker setting on your computer is set to output sound to the external speakers. Check to make sure to the audio cables are plugged into the appropriate input and output ports. If the problem persists, you should try another external speaker.

Check to see that the projector is plugged in and the power outlet functions correctly. Also make sure all the power cables and visual cables don't have any bent pins.

The bulb is probably fading. Bulb replacement is likely necessary. A common mistake is replacing the bulb with a bulb of the wrong wattage which could damage your projector. Ensure the wattage type is correct before installation.
