Re: dag34amb6d0 Backlight fuse
Apparently on your board "L7000" is just part of the track, so there is no component between the main power rail and the backlight rail that can fail.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

I upgraded display from HD to UHD recently, and I think I did everything right, battery was disabled in BIOS, and removed, yet the screen has no backlight. Both the old and new display behave the same way. I checked the motherboard and I see the fv1 fuse, and a fv2 spot for a fuse, but it's missing. Does anyone have any information on whether fv2 is responsible for backlight, or why it's missing? There's a schematic posted somewhere on this forum, but I can't view it as I don't have the hardware right now, since the laptop screen is broken and I run Linux.

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?

Hi everyone:
This is the second time I have my sister's mixer on the bench. First time I identified a blown tiristor......this time I guess it's the thermal fuse (reads open).
My understanding is that it should be (NC) normally closed and open at 85C?????
Could you help me to identify/get a good one? How many amps? I was about to buy a NC 10A, 85 celcius in Aliexpress. (ceramic one)......but I guess is too much.
Wording in the back......... "limitor 16", "T160".
Thanks in advance,
Francesc.... -
