Samsung S22B300B flashing backlight

Hello

The monitor's backlight keeps flashing on and off extremely fast, but there is data on the screen when connected to the pc while it's flashing, i disassembled the monitor and tested the voltages, the side that connects to the leds are fluctuating, so i removed the leds cable and the flashing and voltage fluctuation stops, i changed 4 capacitors on the board, the diode and mosfet connecting to the leds, but to no avail, and there are no shorts anywhere does this mean that the led strip is the problem?
