    Try with extern monitor if you have image and you also can try with other Ram.

      Check for voltage on CPU coils. If below 1,15V than it's the chipset problem 99%. Need to refllow, reball or exchange.

          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...

          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....

          Acer Aspire E5-574-52RH - black screen
          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...

          AOC U34G3XM, new monitor, black screen with backlight on, possible shortcircuit during dissassembly
          by turmix
          Hello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.

          The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)
          At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine

          During another reassembly, I made a mistake, and...

          HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
          by m1ch43lzm
          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...
