Hello friends, does anyone have any ideas? I have an xps 9300 with backlight problems. I already tried the screen on another motherboard but the problem is on the board... I have seen the schematic but I have not been able to find the damaged component... the Fuse is ok, can someone help identify the damaged component please..

this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even... -
Could anyone identify Richtek backlight driver from Samsung LTN173KT01?
There is only "CZ=EL 12M" mark on it. Thank you very much! -
