Does the backlight for the screen come on? Do you have video from the video output (vga, hdmi etc)?

 

In a dark room you should be able to see light come from the backlight when powered on. Do you have more than 1 stick of ram? IF so try 1 stick in 1 slot, then move it to the next slot, if still you have no image, try the other stick in both slots as well. The key is to use only 1 stick in 1 slot at a time to rule out a possible bad stick or bad slot. If you have access to the cmos button cell battery, it would be worth a shot pulling that out to reset the cmos (YOU MUST have the power adapter disconnected and remove the main laptop battery as well to reset cmos when pulling out the button cell battery).

Zingo 156 tried everythingsaid to do, including checking the connections to to and from the screen. Only thing i was unable to do

was to reset the cmos battery. Is there anything else that I can try? Please let me Know.. I should let you know that the motherboard

is getting current, the internal fan is spinning, the hard drive is spinning, and the processor is getting warm.... Unfortunately I don't

have any extra memory to test.....

Was there any light on the built in lcd panel? Did you try an external? If so what was the result? If you have a very bright flash light, you can shine it on the lcd panel and see if any picture is actually there. I am not certain if your model has an inverter or if it is a LED back lit LCD, if it has an inverter, it is possible this component failed. The inverter provides high voltage current to run the CCFL backlight. If it fails the screen may appear black but will still have an image that a bright light may help you see. If there is a back light but no image, it is possible your lcd panel has a problem, or your main board has a problem.

 

If there is no picture at all including on an external monitor, the next thing I would do is remove all components that are not required to get the computer to fully post. Hard drives, webcam, keyboard, mouse, wireless mini pci-e card etc... This would require taking the computer apart. Any component can cause a post failure. You should leave 1 stick of ram in, the built in monitor hooked up to the main board, the cpu and cpu cooler/fan installed and then only use the power adapter (leave the battery disconnected).

 

One thing I should mention now: ALWAYS disconnect all power (battery and power adapter) from a computer before removing any components. If you leave the battery in when removing components, you can cause permanent damage by shorting pins.
