Lenovo Thinkad L540 - Backlight Fuse, dim display ?

#1 Post by AccountSaver » Mon Jul 13, 2020 8:19 am

Hello to all,

I had a broken L540 on the corner, with broken screen and blown fuse, it was showing just fine before.
I changed even the cable,and brand new screen which shows in different laptop so cable & screen are out of question.

I have changed the fuse near the video connector as the board suggests 32V/3A but again the display is really dim, in external monitor it shows great.

Any thoughts ?
