      RS880M northbridge, can go bad. Try to mildy heat heat for a couple of minutes at 200°C to see if it comes back to life. Make sure you don't overheat it, and this will only be a very temporary fix, the northbridge will need to be replaced.
      Also I assume you tried with known good ram sticks and cleaned the RAM slots first.

          Thank you Piernov

          I will reflow northbridge and clean ram slot.

          MY question Did my laptop complete booting ? Or on half way ? Only the picture is the problem?

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

              HP Elitebook Screen blank - backlights but no image

              Hi guys
              I'm trying to fix this laptop screen

              Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

              OK so I have the original screen which works but has lines across the bottom quarter of the screen

              I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...

              Macbook Air M2 A2681 Kernel panics after screen replacement
              by reformatt
              Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

              It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

              Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF OLED Blank screen
              by Kalman27
              We have a Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF for repair. The original issue the OLED screen is blank.

              We have replaced the OLED screen with the exact model, also we replaced the LCD cable, but no luck.

              I think there is something with the motherboard. I don't really have experience with OLED screens so far, so not sure how it should work. I have seen some laptop comes with a separate controller board, but this model does not.

              Also, there is an error in Windows device manager - This device cannot start (Code 10) - Intel(R) Serial IO I2C Host Controller...
