I purchased a backlight driver off ebay, however, they sent a driver (715G6840-M0D-000-004K) to replace the orginal driver (715G6840-M01-000-004K). It didn't resolve the issue, could it be because it was a different card (based on the 2nd set of numbers)?
Well, it has to be the right part and that is likely for a similar model, but not the same model.
This article I wrote explains the problems you are facing.

It's a one way street...from camera to computer...not the other way around. Doing it that way will eventually corrupt the card and sometimes even the camera.

The 2 boards are not exactly the same, the 241 does not have the small transformer installed by the first connector (as shown in the picture) and 241 is for AUOPTO LCD panel T370HW01 V.2.
The 411 has the small transformer on the board and it is made for AUOPTO LCD panel T370XW01.
It may mean that the pin-out of the connectors may not be the same. I would be real carefull about using the wrong board.
By the way, the fuses check out OK?

Hello
If you can see the image on the screen with a flashlight then it's a problem with the inverter.
Good Luck
You are correct, this is a backlight issue! The screen inverter is usually built into a circuit board, if you want to attempt this yourself you will need to access the circuit boards to see which one you need to replace! If you open up the TV and post a picture we will be able to point you in the right direction!
Testimonial: "Thank you for your quick and very helpful response. My husband will tackle that task soon and we'll send photo. Hopefully will be an easy fix. Thanks!"
SOURCE: 47' (sic) LED TV, model number m470vse. Why doesn't the backlight work?
Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.
