the power light of skyworth TV set flashes and can't be turned on
the flashing of this machine light indicates that the switching power supply is basically turned on, but it is not displayed normally because of the circuit failure. ①→ Check whether the voltage of each pin of the switching power supply stabilized oscillation chip is normal. If it is abnormal, check the components around the chip, such as increasing or decreasing the resistance parameter, or breakdown and short circuit. ②→ Check the capacitor for leakage, breakdown and capacity change, especially the feedback capacitor. ③→ After the above inspection and replacement, if the fault remains, the power chip can only be replaced.
