Check the voltage at the backlight output connector during power-on.
Consists of a fuse, varistor (VDR), and negative temperature coefficient (NTC) thermistor to protect against current and voltage surges.
The is one of the most widely used universal three-in-one LCD/LED TV driver boards in the electronics repair market. Manufactured by BoardTech (and often associated with brands like LeZhi or other generic Chinese mainboard distributors), this board combines the main TV processor, a LED backlight driver circuit, and a switch-mode power supply (SMPS) onto a single substrate.
