How to Fix a Hitachi Projection TV

Your Hitachi projection TV produces high-quality images so you can enjoy your favorite gaming, movies and sporting events. However, there are times when you need to fix some audio or video quirks that might appear, like no audio or no picture on your television. Fixing your Hitachi projection television on your own allows you to take care of minor problems yourself, without having to call in a pricey service person to fix it for you.

Things You'll Need

• Hitachi television remote control
• Magnetic coil

Instructions

1. Pull all the connections to your Hitachi projection television and plug them back in. Loose plugs or cables often cause problems, so this may fix your TV.

2. Ensure your television is on the right channel by pressing "Input" on your Hitachi television remote control. Hit "Input" multiple times to cycle through all the available input options to see if your picture or audio displays on one of those input channels.

3. Move items that block airflow above or on the sides of your Hitachi projection TV. Overheating can cause your Hitachi projection TV to function improperly, eventually leading to television failure if left unaddressed.

4. If there are blotches on your screen, a common problem with Hitachi rear projection television sets, wave a magnetic coil in circles about 1/2 inch in front of the screen. Continue waving the coil until you cover the entire screen to demagnetize the television, thus eliminating the blotches.
