Led Tv Power Supply Voltage. Power wire #2 has 450. How to check the power supply on led tv mainboard. A malfunctioning power supply can cause issues such as no power, intermittent shutdowns, or unstable operation. The power supply board, also known as the psu (power supply unit), is a critical component in an led tv that converts the incoming ac (alternating current) voltage. A faulty power supply can prevent the main board from receiving. When an led tv main board is not functioning properly, one of the first areas to investigate is the power supply. At first i suspected the power board. Disconnect the power from the tv and then plug in the led backlight power cable and unplug the mainboard/power board cable. When the tv is connected to an ac supply and turned on, the tv power supply board will received the ac voltage input. From this the power supply board will generate the standby voltage. When troubleshooting switch mode power supply (lcd/led tv) it is very important to check the status of the standby voltage. If driving a led with a series resistor, you need a voltage that is above the forward voltage of the led at your desired operating. The power supply of an led tv mainboard is responsible for providing the necessary voltage and current to the various components.
