Improper A/V cable connections will keep your Hitachi TV from performing correctly.
Your Hitachi TV may go through its life with relatively no problems for quite some time, but eventually some repair may be necessary to keep your TV in prime operating condition. Fortunately, no professional television repair experience is required to navigate the pitfalls of TV errors, and all you need on hand is a magnetic coil.
Power Issues and Coaxial Cable Placement
Always look for the most obvious problems that may impair the operation of your Hitachi TV. Disconnected and loose cables account for many of the issues that plague televisions. Check your power cord for the Hitachi TV and ensure it has not become disconnected from the power source. Similarly, observe the coaxial cable. The trick with the coaxial cable is that any amount of looseness, whether it results in disconnection or not, can still impair the Hitachi TV's display. A loose coaxial cable usually results in what is commonly referred to as "snow". This phenomenon causes "noise" in the form of white dots that jitter across your screen and impair viewing. Fix this by fastening the coaxial cable tighter into the "ANT IN" port on the back of the Hitachi TV.
A/V Cables and Input Selection
Locate your Hitachi TV's remote control. A quick fix for a soundless TV that has a dark screen is to change the video input. The video input must be changed whenever a DVD player, video game system or similar device that works in conjunction with your Hitachi TV is used. Failure to switch the video input back following the termination of use of these devices results in a TV with no audio or video. Hit the "Input" button on the top of your Hitachi TV's remote control to begin toggling through your available video inputs. Continue to do so until you reach the input assigned to your normal television programming. In the event that this does not instantly restore audio and video to your Hitachi TV, approach the back of the TV and look over the A/V cable's connection. One end of the A/V cable has a set of one red, one white and one yellow prong that connects into color-corresponding A/V ports on the back of the Hitachi. The other end of the cable has an identical set of prongs that should plug into color-corresponding A/V ports on the back of your satellite or cable receiver box. If these prongs are not matched color-wise with the ports, switch them up and remedy the situation.
Irregular Screen Blotches
If video inputs and cable connections are not your culprit, you will need to get your hands on one special piece of equipment. It's recommended that you procure a large-sized magnetic coil for use on your Hitachi TV (see Resources). Televisions sometimes become magnetized because they are placed too close to other electronics. Such magnetization causes irregular blotches on the TV. A magnetic coil, when waved slowly in front of your Hitachi TV's screen, will eventually help to negate the effects of magnetization and remove these blotches.
