Skyworth LCD TV 26S15HM This machine is caused by lightning strike, there is no response at boot, direct view 431 burst, optocoupler has black traces; use table to measure insurance normal, but fortunately there is no serious short circuit, put on bad components to boot, or no voltage Output, the power supply block of this machine is STR W6556. Firstly, the 4 feet of the chip start pin are 0V. Obviously, it is not correct to go forward along the 4th foot. After passing a resistor to the starting resistor, there is 5V, and the chip is hung; the measurement is removed. The foot and the 4 feet are obviously short-circuited, and the power is turned on. There is still no voltage output. In the measurement of the 6 feet of 6556, the 8V voltage is still low. The 30V voltage regulator tube next to the starting resistor is decisively removed, and the reverse phase is slightly measured by the 1K file. Leakage, there is no piece at hand, think about it, CRT to tune the voltage 30V regulator tube instead, remove a load, and you're done
