Product introduction
Power fixture can easily detect the faults of LCD power supply board, maintenance is necessary, board-mounted various interfaces can be convenient combination of direct use, greatly speeding up the maintenance progress, so that the maintenance of the power supply board and distinguish between the main board and power supply board fault become simple, the latest version of the performance is much better than the same type, without the need for external auxiliary power start-up. Move, use more convenient.
You may use this scenario below.
1 can not tell whether the motherboard or power plate failure.
2 the power supply board is offline without starting voltage.
3, the output voltage of the power board is too low or too low.
4, when the power supply board is soft, it is good and bad to start.
5 power plate with load differential can not be accurately detected.
6 door-to-door maintenance testing is not convenient, and so on.
There are many more usages for you to find out.

Product description
LCD TV power supply test tooling instruction manual
1. DuPont test line functions from top to bottom:
1. 5V standby (SVSB) 2. 5V 3.12V 4.24V 5. ground wire
6 on off control (STB/PS.ON) 7. backlight switch (BL.ON/BK) 8. brightness adjustment (DIM/ADJ)
2. the 3 switches on the left and the corresponding 3 indicator lights correspond from top to bottom.
1. switch machine control (STB/PS.ON) 2. backlight switch control (BLON/BK) 3. brightness control (DIM/ADJ)
It is dialed to the left to turn on or turn on, the corresponding indicator lights on, if testing the working state of the machine,
Please dial all three switches to the right. At this time, the three lights show the three control signals of the motherboard.
No, the light is high level, that is, turn on, the backlight switch on, brightness on, if not on, turn off.
Connecting the tooling to the whole circuit with the donated test line can monitor the working state in real time, especially for good or bad times.
The fault has a more intuitive judgement.
The function of the 3.4 voltmeters from top to bottom is:
5V standby, 5V voltage, 12V voltage, 24V voltage, voltage display, more intuitive and more eye-catching, more convenient to use.
4. the function of the lower right corner switch K5 is:
There are 5V standby voltage to the left, 5V voltage to the middle, only 12V to the right.
5. the function of the lower right corner switch K4 is:
To the left is to connect three false load resistors to the circuit, and to the right is to disconnect the false load resistor and test the power supply separately.
You can switch the switch to the left. If you are monitoring the working state of the whole machine, you can switch the switch to the right side.
6. if the three switches on the left are turned on and can not light the backlight, you can stir about K5.
Or switch the 3 switches on the left at the same time.
7. warm reminder: the maximum test voltage of this instrument should not exceed 30V, not overvoltage.
Use
The color shape of components may be different because of different batches.
