I switched on the laptop and when start up it shows me all the light but it won't just start up and the screen will be blank... and the DVD light will be blinking continuously
First we need to test if the problem should be the LCD screen.
The easiest and most foolproof method for testing your lcd screen is to
hook up the laptop to an external monitor. If the video output on
the external monitor looks fine, this means that the problem is with
the video connector, with your LCD panel itself, or with the circuitry
that turns on the LCD.
Second we need to disassemble the laptop and find the video connector on the system board (if the video is integrated
on the motherboard) or on the video card that is attached to the
motherboard. Try re-connecting the cables. You may as well locate the
display connector on the back of the end LCD panel. Re-seat that one
too. This way you can be sure that the problem is not related to
connections.
Every now and then the switch located on the
system board that turns the back light of the LCD on and off can become
stuck. If this is the problem then your LCD never powers on. There's a
little switch that detects whether the screen of your notebook is open
or closed. That's the one we're talking about. Try to push it down and
hope it gets unstuck.
Disassembling the laptop to unstick this switch
is an option, but sometimes you can get away with not taking it apart.
Try lightly hitting that plastic switch. But wait, this isn't the only
possible cause, unfortunately. Re-seat the other connectors and cables
that are present around the LCD panel and the video on board (including
the inverter)
