OK Mel, it's your dime.
The LCD screen is bad. It may be just the Backlight, but since you purchased this baby new; it will have LED backlighting. There is NO replacing the backlighting, there is ONLY replace the LCD screen.
Primer if I may;
An LCD screen does not produce light.http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/
(Click on the monitor image)
An LCD screen needs an additional light source.
A Backlight is the additional light source.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)
A CCFL is a Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
Average thickness is 2mm. That is a little larger than 1/16th of an Inch. (-> O <- approximate thickness)
Average length is almost as long, as the LCD screen is in height.

Newer laptops like yours use a series of LED's.
A screen Inverter is used to convert the power (Electricity), from the laptop, for the LCD screen, and Backlight.
LED backlighting does NOT use a screen Inverter.
When an LCD screen that uses LED backlighting, has problems with the backlighting, the entire LCD screen is replaced as a unit.
Is the problem with the LCD screen itself? Could be. The entire LCD screen is replaced. Either way, replace LCD screen.
Now,....the above is just GENERIC information.
I need the laptop manufacturer name, and model number. The model number may be on the Palm Rest Cover, to the right of the Touchpad.
It WILL be on the bottom of the laptop.
Post back in a Comment.
This way I can see if there is a link to give you for a free Service Manual, and perhaps some pictorial information also.
Then I will guide you step by step, and we'll get that LCD screen replaced.
It isn't hard at all, I assure you. YOU CAN do it.
(Psst, they don't have them anymore because it was a special sale.
Whoever the laptop manufacturer is, though; is obligated to repair it. Kinda hard to get them to replace the entire laptop. DOES happen though.
Laptop was like that from the factory. Is not the consumer's problem, is the factory.
I don't care if it came from Best Buy, Tigerdirect, Newegg, or your uncle; the FACTORY is obligated to repair it. DOES NOT matter if it was a Black Friday sale, Christmas sale, or an Easter Egg hunt.
DO understand about the time frame thing, though. Plus DO commend you for your willingness to repair. It is people like you that built the world, not sat by and watched)
