Lenovo ThinkPad E15 AMD 5B21C82193 Backlight Fuse Location. Beware of the screen compatibility!!!
In this video I was trying to fix no backlight issue on Lenovo ThinkPad E15 after the customer stated it stopped working after memory replacement. During failed attempt of the fuse replacement I realized that the issue is in the screen itself. Another phone call cleared the situation. Apparently there is a screen compatibility issue on this model that will cause blown backlight fuse and no backlight.
