    Alienware 17 LA-9331p black screen

    Today I got an AW17 R1 Ranger with 120Hz 3D Panel, I7-4800mq, 32GB RAM and a 780m. When I turn it on the screen stays black but with no beep code. When I plug in HDMI the Display stays black and I get 8 beeps. Also I tried with an M17X R3 60Hz 1600x900 LCD, also 8 beeps. The same thing is with a GTX 770m, 860m and MSI 780m. After that I did a Power drain and it gave me first 5 beeps and after that the same 8 beeps.
    Anyone who has an idea what that could be?
    If it is a Motherboard issue, which component is affected?

      i suspect the lvds cables will be a different part number too.The first thing to try is a new cable.If theres still nothing then it could be the EDID thats corrupt

        Yes, the M17X R3 is only LVDS. That is the slot with no holes.
        So I have to try a new EDP Cable?
        And where to find the EDID?

          Ok, I found the fault. It was the EDP-Cable on the back of the LCD itself, which was loosen.
          Never thought that it could be so easy.

            Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
            by HTR-Informatique
            Hello,

            YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

            I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

            On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

            I also changed the screen because the PC fell and the screen was broken.

            I changed the battery with a new and original battery.

            I also had corrosion/oxidation on the...

            A1312 (27” iMac 2009-2011) A1407 (Thunderbolt Display) A1316 (Cinema Display) Display Black Screen Repair

            Problem

            This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

When the black screen appeared, my legion 5 pro was connected to my external monitor...

            by DaniK
            Hi everyone,
            I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.
            Laptop came in for a SSD upgrade, took everything apart to install the SSD.
            Everything started after modifying BIOS settings to boot UEFI instead of Legacy.
            Laptop works fine, i installed windows 10 and drivers/updates, everything works ok(when it works)
            The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image

            Symptoms are:
            - random black screen after displaying Acer logo...
