No Display on Compaq Presario c700 after changing LCD - Checked conn.

Hello,

I have an Compaq Presario c700 laptop that needed a new LCD since the old one was cracked. So I purchased a new LCD, looked at the repair manual here and changed it exactly as instructed.

So now when I turn on the laptop, I see the lights indicating that the laptop is on and that there is disk activity, etc. but there isn't any display. I do know that the display is connected because there is a slight change on the display from light black to dark black.

I have also opened the laptop and checked the connectors. Everything there is connected as it was to the old display.

Is there anything else that I need to do or check? Thank you for your time.

Regards,
Chris K.

You might try starting the laptop in Safe Mode (press F8 as Windows is about to start) in case the display settings were wildly wrong in Windows Normal Mode.

Have you checked the laptop via an external display ?

If the external screen is okay and zero on the new screen, it's probably the connector or the screen.

You can check if it's backlight failure by shining a torch at the laptop screen (obviously with the computer running and preferably Windows visible on the external monitor -- though also check with external disconnected in case the laptop flips between the two)

Incidentally, though mostly this is just common sense advice, I have done a similar screen transplant -- though it was between two identical Dells

I'd like to know what was your final result as I am going to change my notebook screen soon. If you can share your experience with me. Many thanks, /jim
