How to Fix a Projection TV

Projection TVs come in many shapes, sizes and designs. Some are flat screen others are DLP models. Whichever your pick, they enhance any TV-watching experience. Sometimes, though, they run into problems you might be clueless on fixing. These can include power, display and sound problems. Before you rush to a support center, there are many troubleshooting steps and guidelines you can take to repair those common problems.

Instructions

Power Problems

1. Check your AC cable and make sure it is connected. Try powering on your TV. Check for any lights.

2. Check the fuse or circuit breaker if your TV is still not turning on. Use your owner's manual to locate the fuse box as it varies with different TV models. If the fuse is blown, replace it.

3. Let your TV cool down for a while if the LED light on your TV is blinking abnormally. This observation depends on the model of your TV. Use your manual to troubleshoot changes in LED lights.

4. Contact your manufacturer if your TV is still not turning on. It might need servicing.

5. Check your sleep timers if the TV turns off automatically. If that does not solve the problem, check your power outlet in case you have a power problem.

Image Problems

1. Check the input selection if your TV screen is black. Press the input button repeatedly until you locate a channel where your broadcast signals are.

2. Check your image settings if your images are ghostly or distorted. If your image settings do not fix your problem, check your antenna. Reposition it where necessary.

3. Check the connections between your broadcast provider and your TV. Make sure they are properly and tightly connected.

4. Replace any wires that are old and corroded if your pictures are still unclear. Try resetting your TV back to its original factory settings. Use your manual to locate this feature if your TV model has it.

5. Contact your TV manufacturer if your images still do not show up. Your lamp unit might be damaged and needs to be replaced. The unit location varies with different models. Use your manual to locate it, then contact your manufacturer.

Sound Problems

1. Check the audio settings if your TV volume is low or nonexistent. Make sure the sound output settings are on. Use your manual to adjust these settings. Make sure the volume is not on mute.

2. Check your audio connections from your broadcast receiver to your TV. Make sure they are properly connected. If your sound is distorted, clean the audio connectors on your TV with a clean cloth and some mild alcohol solution.

3. Try changing the channels if your audio is out of sync with your video. There's a possibility this might be a problem with the TV station.

4. Contact your manufacturer if your speakers are still fuzzy and distorted. Your speakers might be damaged and need replacement.

Remote Problems

1. Check your remote lights when pressing buttons. Your batteries might be dead. Replace the batteries and try using your remote.

2. Remove any obstacles that might be blocking the signals. Operate the remote a little closer to the TV if you are still not seeing change on your TV.

3. Make sure it is on the right settings to operate your TV, especially if you have to set up your remote to work with multiple devices such as a DVR and receiver.

4. Press the reset button on your remote if it has one. This varies with different TV models. Hold the reset button for a few seconds, then release.

5. Contact your manufacturer if your remote is still not working.
