    Asus X455LD Rev. 2.1 Internal Display Problem

    Hello everyone...

    Just got confused with this mainboard, it's working flawlessly using external display via VGA port. After entering windows 7 welcome screen, internal display turned on by it self and it's cloned to external VGA display. But without external display attached to VGA port it's nothing on internal display and it's not booting to hard drive, all power rails is present when using only internal display except on lvds connector, only these pin has a voltage on it:
    pin 1-3: 19v
    pin 10, 12, 13, 20, 37, 40: 3.3v.

    Updating bios same result, try to jumper U4601 pin 3 to pin 5 to get voltage on lvds connector pin 38 & 39 only resulting black LCD no image and backlight. Tried reflow the CPU same result.

    Any help would be appreciate it, thank's in advance

                A1534 2015 820-00045 internal display not detected, but external works
                by baglaivlad
                Hi everyone!
                Trying to repair A1534 2015 macbook. The keyboard and touchpad was liquid damaged by coke, but the MLB has no signs of corrosion. The laptop successfully turned on, but missed a display flex. Replaced keyboard, touchpad and display flex, but still no image on the internal display (no backlight as well). When connecting to the external display the laptop works just fine (I have an image).
                It seems like internal display is not recognized. I tried multiple known-good displays and display flexes, the outcome is the same: no life on the display.
                It lead me to believe...

                a2141 820-01700 internal display not working / external works
                by eurowill
                Hey ya'll this is my first post on here. I recently aquired a used/broken 2019 mbp 16 a2141 with the 820-01700 board. Seller told me that the laptop needed a new lcd. However upon doing some troubleshooting i found out the lcd is fine.

                Laptop boots like a normal, plays chime, touchbar lights up however there is no image on the internal lcd. If i connect and external monitor while its already on, nothing happens and no image is displayed on external. However if i restart or boot the machine while its plugged in, the external then works and a backlight is now visible on the laptop....

                Asus G15 5980HX - 6800M - No Display on Laptop - HDMI/Display Port external monitor works fine. Fried Component.
                by amuse619
                Hello!
                Looks like I fried something when my EDP cable got squeezed on the hinge. I replaced the cable but still no display. Laptop works fine with external monitor connected through HDMI and Display Port-USB C port. I took it apart and I see a burnt component. Can anyone help me identify what this component is? I tried to use schematics for another G15 but it does not match on the amount of pins and size. I attached pictures. The component has a label on it - (21A29)

                Laptop is a Asus G15 Advantage Edition 2021 Laptop Ryzen 9 5980HX - 6800M...

                820-01041-A Without BOTH internal display, And External and Backlight.
                by MtapeK
                Hello I have an 820-01041-A that does not have BOTH display and Backlight. The MBP was working properly to wake up without Display overnight. I have Tried SMC and NVRAM reset they both are not solving my Problem. The CapsLock on the KeyBoard, is working when you power it ON, and when you plug the Charger it's Responding with a sound that signifies the MBP has BOOTED in to SYSTEM. I have tried an HDMI (external Screen) its NOT Displaying anything. Also the INTERNAL Display Shows nothing.
                1. I have Changed U9850 and the results are still the same, Discovered that the IC is working on a Good Known
