Re: no display on laptop screen
Have you tried presseing your function key and F2? This will toggle your displays on and off. It is generally used for when you have an external monitor and would like to switch video between the monitors.

first check your display in monitor with the help of vga cable attach your laptop in the monitor,if display comes in the monitor it means your screen faulty .or if display cant seen on monitor it means there is an fault on MOTHERBOARDS BGA CHIP.
First, connect an external monitor, turn on your laptop, then pres fn+f5 or f7 button to switch signal to external monitor. If it's not working, then your motherboard (if your video card is integrated), or your video card should be replaced.
If external monitor is working, than you have problem with connections from motherboard to display, or display itself. Broken video cable (or cable has come loose from the connector), broken lid switch, display backlight or inverter.
I work for a computer company and i am sorry for what has happened to your computer. Regarding the display that your screen shows I'm afraid but let me get straight forward. The LCD screen is broken from the inside. Probable causes:
Computer must have been accidentally dropped.
Force applied on top of the laptop which caused the back side of it pressed.
Heat that escapes from the motherboard, goes through the keyboard straight to the LCD which causes liquid elements to expand and breaks LCD from the inside. That's why it is always advisable to let the laptop cool before closing the LCD screen.
Test the laptop using an external monitor If this works fine, then the issue is with the screen, or possibly the vga cable. I notice this is referred to as a compatible screen, was this obtained new, or is it 2nd hand. Although most 15.4 screens fit most 15.4 laptops, some do not display correctly, this might be your problem. If you know the screen to be good I would suspect the connection at the back of the screen
If this still shows issues with an external monitor, you have a problem with your graphics chip on the motherboard
Your display has a flourescent tube behind it, and it sounds like either the tube or the driver board that powers it are going out. This is a high voltage device, so I suggest getting a technician to look at it. Both are not that expensive, and you will probably pay for in labor than the parts.
The display has to be taken apart to resolve the issue by replacing these components.
If you try yourself, look at the tube and see if it looks black on the ends (burnt look inside the tube). This means the tube is bad. If it is all white, your board is bad. Look at the leads from the board to the tube to be sure there are no cuts or broken wires. Nowdays it seems the tube comes with the board as one unit, so you might be looking at around $50.00 materials average for this kind of fix. Hope that helps..
