Move any items that block airflow above or on the sides of your Hitachi television. Overheating can cause your TV to function improperly, eventually leading to television failure if left unaddressed. If your TV does overheat, clear the area around the TV and let it cool down completely before you try to operate it again.

Use a magnetic coil to address magnetization problems that can cause blotches on your screen, a common problem with Hitachi television sets. Wave the coil in circles directly in front of the television screen, about half an inch away from the screen. Continue waving the coil until you cover the entire screen to demagnetize the television, thus eliminating the blotches.
