      before asking schematics better to tell what did you try to do. Another screen for example... or reconnect original one

              what about voltages on 9-10 and 19-20 pins of JEDP connector?

                  You can use any similar schematic with same pincount of edp connector. I think E791 will match perfectly.

                      Aorus 17G YD laptop, broken display, could not switch to external monitor
                      by ArchangelGabriel
                      Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have

                      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....

                      Razer Blade 15 no external display with attached screen disconnected from motherboard
                      by plyanthony
                      Computer in question : Razer Blade 15 2020 Base Model
                      Model# RZ09-03286E22
                      BIOS CHIP: WINBOND W25Q128BV

                      What I'm trying to accomplish:
                      I want the computer to properly boot with an external display with the attached display disconnected from the motherboard. I have a CH341A programmer and full capability of modifying the BIOS easily. I Have tried various setting changes to no Avail.

                      What I've tried thus far: Too much to note and I really dont remember everything I changed but here it goes.

                      W/Stock BIOS - 1.06:
                      Disconnect the...

                      Lenovo Ideapad Flex 5 14ITL05 Only working on external display
                      by lawrenceptrini
                      Hi Guys,

                      LENOVO IDEAPAD FLEX 5 - 14ITL05
                      BIOS VERSION - FXCN24WW
                      EC VERSION - FXEC18WW
                      MTM - 82HT0004US
                      SERIAL NUMBER - R9130MDP
                      CPU - i7-1165G7

                      This laptop powers on but shows nothing on the internal display.
                      However, if I attach an external display it works fine.

                      Observations: When I shut down the laptop from windows,
                      the fan remains spinning until I close the lid. If I leave the lid open
                      the laptop will restart on it's own although I select shut down from windows.
                      Also, when I check the voltage on the...

                      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...
