Models with a voltage doubling rectifier function incorrectly in the voltage doubling rectification state under normal mains power conditions (used only in some new remote-controlled color televisions).
Pulse Width Modulation Circuit Issues
Oscillating capacitor capacitance has decreased.
The main load (line scan circuit) was not operating, which caused the switch mode power supply load to become lighter, leading to an increased output voltage. (This applies only to power supplies that indirectly sample the voltage regulation loop, i.e., the voltage regulation sampling is not directly taken from the B+ output.)
