PURPOSE:To eliminate noise on a screen caused by the action of a degaussing coil and stray capacity. CONSTITUTION:When a switch 2 is turned on, the action of a positive temperature characteristic thermister 7 and a degaussing coil 6 causes degaussing. In this case, a negative temperature characteristic thermister 8 parallely connected to the degaussing coil 6 reduces oscillation frequency caused by the degaussing coil 6 and the stray capacity, resulting in reducing noise. |
