Abstract
An automatic color temperature adjusting system for a television receiver which is capable of eliminating an unstable picture condition during the turn on transition period. The automatic color temperature adjusting system has a gain control circuit associated with a feedback loop for controlling the amplifier characteristics of an amplifier in each color channel. The gain control circuit is responsive to the turning on of the power supply to lower the gain of each amplifier to a given level. The gain control circuit adjusts the gain of the amplifier to gradually increase the gain to reach a normal gain level after a given period of time.
