    820-000138, no external image

    Hello!

    I have a 2015 15" (IGPU-only, NO DGPU), 820-00138..

    Has a broken screen with some liquid spill around U7310 pin 11 to 14, C7316, C7319, C7318 and C7317..
    All caps replaced and U7310 chip cleaned and resoldered properly..

    The computer POSTs now, I try another screen and it shows image successfully...

    But for some reason it's not showing an image externally.. I tried the HDMI output and both of the thunderbolts outputs with no luck..

    Honestly I have no idea where to start now and a bit lost..



    Help?

    Thanks!

      [ SOLVED ]

      Apparently all three ports were really really dirty and none of them were communicating properly.

              Macbook Pro A1989 - No image, working fine with external monitor
              by Madoy104
              Hi everyone,


              I have a MacBook Pro A1989 that was likely exposed to liquid. It doesn't display an image on the built-in screen, but the screen is backlit (you can't see the Apple logo or any other elements when held up to light). The laptop provides 20V and 1.5-2A, and it works fine when I use it with an external monitor. Currently, the connector for the display (J8500) is disconnected. I'm writing to ask for help in diagnosing the issue. I've heard that when the J8500 is exposed to liquid, the processor pin responsible for the display might short-circuit, and I'd like to know...

              dell la-b843p image only on external
              by f-bone
              Hi guys,

              this one seems to work except that there is no image on LCD, only on external via HDMI. I have flashed the bios with a cleanME one and measured voltages at GPU (0.9V) and LVDS connector (LCDVDD_LCD is 19V and DCBATOUT_LCD is 3.3V). I can see the LCD going black after power on but no image. I shed some light with a torch but there is no image or activity at EDP_TX0/1 using the oscilloscope. I also tried a different panel.

              any ideas are welcome.

              br,
