How to Repair Laptop Graphic Chip Failure

When your laptop turn on but screen shows you no display, black screen, horizontal lines, vertical lines, or creating dots on the screen that mean you having a laptop with a faulty graphic chipset. This problem can occur with any graphic chip based laptop either you have Intel, AMD or Nvidia graphic card and caused by faulty heatsink airflow.

The Graphic chip soldered on the laptop’s motherboard, when you run your laptop for a long time with bad airflow in heatsink, that graphic chip solder got starts to separate from the motherboard and that cause video failure. The graphic chip repair by reflow graphic chip soldering, reflow means providing particular heat on the graphic chip to melt the solder and re-joint itself to the moatherboard and that will fix the problem.

Disclaimer: Please follow the below at your discretion, as we will not take any responsibility for problems encountered or any damage that could occur. This may also void your warranty. You are repair graphic chip at your own risk, this is general information.
  • Step 1: disassembly your laptop and take out your motherboard from the laptop’s case. to disassemble your laptop in a right way, make search on internet how to disassemble your laptop.
  • Step 2: Put your laptop’s motherboard on a repair table and start covering your the motherboard by the use of foil paper and leave the graphic chip out.
  • step 3: Power on the heat gun and set the temperature at 300 C° with the low air pressure (Make sure you’ve set the air pressure low; if you don’t then the heat gun will blow all the small components off from the GPU chip) and preheat the gun for about 30sec. After that provide the heat on the graphic chip at the distance between 1 to 2 inches for 40 second with rotate the heat gun clockwise and anti-clockwise while proving the heat gun to the Graphic chip, don’t hold it still.
  • Leave the motherboard to cool, then assemble back your laptop and check it.

    Got the E-25. Looking for schematic so I can modify the amp with capacitors that will pass the lower freiqencues as per typical harp amp mod. Mine is clean too. Different speakers provide different effects, though I got a great sound in the pawn shop with original speakers.

    Hello I have a question:
    BGA rework is mostly inefficient to invest on. specifically in GPU replacement. technician has to spend hours on BGA rework and does not even know if the chip is good or bad. mostly, no long-lasting GPU chip can be found. that is why many technicians have doubt whether buy a BGA machine or not.
    I am not experienced in BGA rework. So I have got a question.
    I know GPU replacement will not last much. Despite GPUs, recent BGA CPU/PCH chips have many more tiny balls underneath (more than 1000). So the questions are:
    How much is the success rate if a skilled technician desolder a recent BGA CPU/PCH from a donor board and solder it onto another board?

      The reliability is depending from quality of the process,you must use the right balls(i change the ROHS hi-temp lead free for leaded ones),clean the board from old solder,repair solder mask if needed,use realy good flux and right amount etc..Dont forget to dry out the board and chips..The process itself take maybe 1-2 hours but you must calculate also time for drying in bake chamber- personaly minimum 6hours at 105Celsius ..
      Quality of bga machine is not so important,you need only two heaters with time-temperature control and good heat homogeneity ,more important are the other things around…
      If you make everything good and you ensure good heat transfer from chip then must last as long as the chip itself
