First connect to external monitor and see if you see an image.

Then boot to F12 and choose diagnostics.

Hi hsgupta,

Try releasing the residual charge from the system. Here are the steps:

  • Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer including the battery and AC Adapter.
  • Press and hold the power button for 20 seconds.
  • Reconnect the battery and the adapter. Try to restart the computer and check.

If you are able to boot, run diagnostics to confirm hardware functionality. Here are the steps:

  • Restart the system and immediately start tapping the 'F12' key to enter the 'Boot Menu'.
  • Use the 'Down Arrow' key to highlight the 'Diagnostics' option. Press the 'Enter' key.
  • The diagnostics will begin. Please note the exact error message/code, if any appears on the screen.

Also, check if there is any issue with the LCD by running LCD BIST (Built in Self-test). To run the LCD BIST, press and hold the D key on the keyboard while pressing the power button, then release both at the same time. This will initiate A grey screen, then Red, then Blue, then Green then White, to allow you to inspect the entire LCD for color purity on each screen and to better identify defect such as cracks in the LCD or stuck pixels that may not be apparent in a normal viewing mode.

As suggested by Paul, connect an external monitor to the system, to check if you are able to get the display on it or not. If you are able to get the display on it, then it appears to be a failure either LVDS Cable or the LCD itself. If you are comfortable opening the system, I would recommend that you first try reseating the LVDS Cable and check if that resolves the issue or not.

If the issue still persist, then first part replacement I recommend is the LVDS Cable and then the LCD. Please refer to the Service Manual for instructions on replacing the hardware components. Please follow the safety guidelines.

Hope this helps. Please reply if you have any questions.
