I accidentally replaced screen with power cord connected(laptop was powered off)
I realized something burned when I saw the spark from the hd cable connector.
The screen still works, but no backlight. I can barely see the image on screen with lamp.
I ordered a new screen, same problem. So I guess the screen might be ok.
I did a research online, it looks like I burned a fuse for backlight.
Could someone help me with identifying the fuse? Thanks
T420 no backlight bad fuse?
