Question about Dell Inspiron 6400 Notebook
At power up or restart, more then often enough, the laptop monitor will refuse to turn on. However, it will come back to life now and then. I can assure you that the problem is neither the Inverter PCB or the backlight/LCD itself. How do I know this, because I've already changed both and the problem is still there. The video cable, also, can not be the problem because the monitor will sometimes turn on, usually by having to press F8 together with the power button, or having to remove the battery or the AC power, one or the other, and then the Laptop monitor works fine with no problems. Until I re-start or reboot the laptop and ther we go again. Yes, an external monitor proves that the video PCB is good, but can there be a part of the Video Circuit that works seperately with the laptop then with the external monitor ? One things for certain, I have not found the solution yet.
Try to update your video driver. If you already tried to check on the external monitor and no problem then it's your LCD video or mother board is faulty. If you updated the video driver and still the same problem then it's your motherboard that needs to be replace.
Note: If machine is under warranty no need to pay for the repairs.
