820-2523-B S0 state, but no backlight

[captainmac]

I've replaced the fuse, everything else seems to measure normal.
board is fully working apart from this, boots to a question mark flashing (seeing this with a flashlight on my test-LCD)
The voltage at PPVOUT_S0_LCDBKLT (pins 38,39,40 at LVDS connector) measures 37.2V
Does that mean something specific? Don't have the LVDS connectors in stock anymore, but maybe someone has a clue going from the voltage alone?

Tried known good screen? 37 sounds like it should be working.

OK, so have replaced the LVDS that i stole from a donor even though its fucking warm in here and i didnt feel like it.
Got backlight back for 5 minutes, but then fuse blew again. What could be the reason for the fuse to blow? I'm new to this stuff (for some reason, havent had almost any backlight issues in so far, only like 5 and they were easy) and trying to learn!

Bad connector and/or cable. Replace them both as they will burn each other. In rare cases it can also happen on the LCD side, so inspect the 3 pins that carry the backlight voltage there too.
