Hello everyone, I am still a 20-year-old young man from Wuxi. Today I am repairing a 32-inch LCD TV with a large size. I have been diagnosed with a light bar. I am too lazy to go online and then simply use a 24V LED soft light strip to be divided into 6 segments. inside. Because it is an integrated board, no matter whether the switch 24V is always available, this can ruin me. Later, a 12V relay is completely removed on the rice cooker. The relay has 4 feet, one ground and one connected to the screen voltage of 12V (because Only this voltage is controlled by the switch machine, which can perfectly achieve 24V turn-on. There are two more connected VCC in and VCC out, so that the relay can work through the switch to make the light bar work! The brightness is the same as before when installed.
