    Samsung NP700G start but CPU didn't get HOT only Black screen!!

    The Northbridge gets too Hot, i dont Know of the Temperature is normal? But i think its too hot?

    Mainboard code is: BA41-01944A CPU is Intel core i7, and the Videocard is MXM!

      I am working on a toshiba with an intel core i5, also just a black screen. I havent fixed mine but I can at least tell you that the intel pch (northbridge) gets very hot at idle and its normal. I thought there was something wrong with mine when I touched it but normal idel temp is around 60c, if it gets over 80c then there could be a bigger problem with it.

      Good luck with your repair.

              Hi tata,

              I'm having problem with my laptop NP700G7A.
              Its frequently freezing with the black screen.
              My suspect is failure on the GPU.
              i tested individual parts of component, and only graphic test is failed.

              I need ur guide how to replace GPU/Graphic cards in NP700G7A.
              Steps how to open the things and replace it.
              I did tried to open all the screws and back cover but i cant reach and open the GPU.
              I suspect GPU is located on top cover which is under keyboard.
              But i cant find a way how to open the keyboard.
              I did tried but just cant get it right.

              Thanks in advance.

                  Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                  by Mgiffune
                  I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                  I ordered a supposedly ‘new' Tcon board this time, and                  ...

                  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....

                  Samsung UE50KU6070 black screen
                  by totof
                  Hello,
                  I have my TV model UE50KU6070 which I am trying to repair.
                  BN41-02528A / BN94-10800C motherboard.
                  If I disconnect the motherboard from the power board, the backlight works. When the motherboard is connected the backlight works but the screen remains black.
                  When I plug the TV into the electrical outlet, the standby LED lights up but no reaction to an attempt to start it with the remote control for about 1 minute. During this minute the TV consumes about 20W.
                  After one minute the consumption drops to 0W and the TV can turn on with the remote control but...

I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...
