My MacBook is under Apple Limited Warranty Cn I can take it in to a Service Provider to be repaired for free?

I posted an earlier question regarding a white vertical bar that appeared on my MacBook screen. I discovered that the screen or video card has been damaged. I am under Apple "Limited" Warranty until mid September 2008. Does this mean I can take my laptop into an Apple Service Provider and have it repaired or the LCD screen replaced for free?|||If the hardware is faulty then yes you can.
