820-3437 missing backlight
Liquid damage arround lvds. I replaced LVDS connector and now I have 39.6V at lvds pin 3,4. I can see blinking folder using lantern.
39.6V is enought? This mean U7701 (LP8550) is working well?
Then there is no continuity between the backlight pins and the LCD. 39.6V is way too high and indicates that there is no load on the rails. Could be badly soldered connector or a bad LCD/LCD cable.
