    G75VW eDP / lvds lcd

    G75 series is capable to drive two lcd type on two different connectors on motherboard.
    I have a motherboard with both connector, one for 50 pin eDP 3D lcd second for 40 pin lvds lcd. Both connector and its circuit works well.
    I have a problem with a gtx670mx vcard, it work well with 40 pin lcd but with 50 pin edp it not send any signal to lcd. I inject 3v to some pin and lcd receive correct voltage and backlight is on but edp video signal are missing.
    Someone can explain how edp works respect lvds ?

    It often needs to be set up inside the BIOS, but on consumer BIOS those options are hidden. Maybe you have a jumper setting on the motherboard, look at the schematics.

      Dell ATX PSU won’t start, but forcing it works fine?
      by CapLeaker
      Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.

      Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing. O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

      Samsung un82ru88000f - Boot loop sort of but can correct with taping of LVDS ribbon
      by NolesFan
      Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...

      MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
      by rounin
      Hi everyone,

      I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

      🛠 Original Issue
      The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
      Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

      I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

      ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

      Kenwood SW-505D no sound issue and pops from time to time when it works
      by ex250
      Hello mates,

      I bought this subwoofer a few days ago used and blind and it works erratically, as far as I could see, it has been tampered with, the speaker is not the original one and of 8 Ohm when it should be of 4, and there are some welds like reworked by the boards.

      It doesn't have much power (expected more from it) and it distorts if you increase the volume over the middle, maybe it's because of the high impedance of the speaker. The problem is that it has sound when it wants, the led panels all work correctly, you can hear the power relay on power on, but right now...

      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....
