I don't believe admonishing someone, for their selection of place where they bought a part, is considered a solution.
[Not sticking up for Ebay, or the sellers, but you wouldn't believe the number of computer parts I have purchased, and with only one bad deal. {Money returned, however}
Therefore I offer the following solution;
DIAGNOSE
1) Let's start with the basics, j_patterson9
Primer:
An LCD screen cannot produce light by itself. It needs an additional light source.
A Backlight is the additional light source.
A Backlight can be a CCFL or a series of LED lights.
The Samsung R519 series of Notebook PC's can come with either one. Just depends on what option was chosen.

Now,....which version was your old LCD screen?
Which version is the replacement LCD screen?
They will NOT interchange.
Also,...an LCD screen, and a screen Inverter are a MATCHED unit.
A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale;
Average Width of the lamp (Bulb) is 2mm. That is a little larger than 1/16th of an Inch.
Average Length is almost as tall as the LCD screen.
Just so you can see an average CCFL used for a Backlight,
http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.
The thin plastic frame in front of the LCD screen, is the Display Bezel.
(Also may be referred to as LCD Bezel, Display Panel Bezel, and I'm sure a few others I'm forgetting at the moment. It's up to the individual laptop manufacturer as to the name )
Right behind this plastic picture frame looking object, (Display Bezel), and mounted towards the bottom of the LCD screen, is the Inverter.
(screen Inverter)
This small circuit board could have received damage also.
ESPECIALLY if the video cable was damaged.
Just an example of the screen Inverter,
http://samsungweb.co.uk/index.php?main_page=product_info&products_id=1611) LCD screen:
On the back of the LCD screen (Old one) is the manufacturer code.
THIS is matched up to the replacement LCD screen, to know you are purchasing the correct replacement.
If the entity does NOT have this information available, move on to another entity.
2) Video Cable. (Also known as Display Panel Cable, Display Cable, etc)
Test it.
Use a multimeter set to Ohms, and perform a continuity test of each wire in the cable.
This way you can test to see if any wires are stretched, and/or broken.
If you do not own a multimeter, or do not have access to one, may I suggest purchasing an economical version?
Average cost is around $8 to $12, and available at a multitude of stores.
An auto parts store is but one example.
Need to know how to use it to perform this test? Simply state so in a Comment, after you purchase it.
Tips:
A) Although a video cable MAY look to be fully connected on the back of an LCD screen, all it takes is a very minute (My-Noot), loose connection, and you have your problem you stated.
Re-verify the video cable is completely and fully connected to the back of the LCD screen.
It would also be wise, of course, to recheck the motherboard side connection of the cable.
3) screen Inverter:
To test a screen Inverter requires a sensitive multimeter. Read, fairly expensive,
http://www.fonerbooks.com/test.htmWithout the proper equipment to test the screen Inverter, most consumers just replace it. (Low cost, and ease of accessibility to replace, is also a contributing factor)
What do I see just off the top, J?
The wrong LCD screen, and/or possible damage to the screen Inverter.
However it is up to you to Diagnose, and tell me.
Awaiting your reply.
