This laptop was working ok, video and backlight.
I opened this laptop to replace a cap and now when I tested, has video (can see blinking folder) but no backlight. I checked led driver LP8545 and has a hole. I replaced it with new one and check for short before and after the diode. No short. After replacment I do have 25 at PPVOUT_S0_LCDBKLT. I check this on diode and on lvds connector, but still no backlight, only blinking folder.
I tested with another working screen and lcd cable and no backlight. What is next to check?
