Yup. Bad lcd. If under warranty, have the manufacturer replace it. If not under warranty, visit ebay for the least expensive lcd's. Won't find them cheaper anywhere else. Just buy from a seller with a decent rating. Some are offering 100-120 day warranties on new lcd's. You can also find used ones there, as is.

Can you plug the laptop up to an external monitor and keyboard, and test it that way?
Is it possible that the laptop is currently set to use the external monitor instead of the default one?

Try to twist the laptop bottom when you turn it on. Some logic board issues are caused by loose chips, when you twist the bottom firmly, they will make contact and the laptop will start up. If that happens you can either twist it each time to turn it on or replace the logic board. If it's an AMD core duo based laptop, those CPUs sometimes tend to die from heat and cause an issue like this. Just replace the CPU they're 30 bucks on ebay. <a href=http://www.portatronics.com>Laptop Repair NYC</a>

The CCFL lamp has been partially damaged and could fail completely any time.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
