Does anyone know the location of backlight fuse for Thinkpad L440?
I have tried with 3 different screens and two flat cables. Screens are from T440 and I know they work just fine.
Result is always the same. You can barely see picture when exposed to flashlight or direct sunlight.
External screen works fine.

Re: L440 backlight fuse location?
Look for a small fuse near the mobo LCD-connector, usually marked with letter P on top.
The name could be printed nearby, such as: F1, F2, F3, etc.
It's a 3A/32V/Fast fuse (in different sizes: 0402, 0603, 0805 and 1206).
Measure for continuity with a multimeter.
Piggyback solder the new fuse on top of the old one.

Still NOT a great day for a Guinness! (the Real Black Stuff).
