Changhong 3D43C2000 plasma power supply board is damaged, check the QS801C, QS802C breakdown on the power supply board, DS820, DS821 open circuit, resistance RS804, RS806, 20 ohm resistance damage, replace the above original power board VS, VA still no voltage, and finally find out It is a chip that writes 25600, 2CM, A991. The power chip is shorted to ground. At that time, I didn't know that the code on the chip was his model. So I took a chip from my other plasma board and wrote 25600, 06M, ALDV. The chip function was almost replaced, and the VS200V was normal. Y board TV boot heard the Y board rang, VS voltage disappeared, look at the Y board, suddenly realized, Y board C5100, C5057 burnt, after the result VS or short circuit, check found Y board 5N50, 3N50, bad two FGD4536 is bad, 30N43P is bad. Since the 30N43P is not replaced by the same model with RJP30E2, after the other models are replaced by the same model, the screen does not see the grating when the screen is turned on. However, I did not protect the VS voltage during the test, and the TV was found to have a subtitle tour on the screen. Move, it seems that the TV has been repaired, because I used the power supply insurance when I tested the machine instead of the bulb, so there is no secondary damage to the power supply, we will pay attention to future maintenance, the power chip I used to write the model online, see who knows Power chip model, after all, my other power supply is fully removed, the TV screen S43AX-YB02. Samsung screen, power board PSPF231503B, LJ44-00246A. Hope that anyone can pass the machine power board map everyone share in the future.
Differential pressure sensor (DPS) is a sensor used to measure the difference between two pressures. It is usually used to measure the pressure difference between the front and rear ends of a certain equipment or component.
Looseness often occurs during installation. The transmitter is connected with the three valve manifold. The bolts should be tightened diagonally. Generally, they cannot be locked at one time. The sealing ring should be densified during the installation of the three valve manifold.
