I've reviewed some of the YouTube videos and particularly the flashlight test which indicates a bad backlight driver. I want to confirm that is true.

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.

SOURCE: Pictures taken can be reviewed in the camera. But,

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

SOURCE: Seiki led tv has sound but no picture. The picture can be seen with flashlight. We tried resetting default on menu with tech support, still no picture. Has no backlight. Which part should we replace?

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.

2nd try see last sentences....lg led 32ln5310 tv, sound but no picture, no backlights, nothing visible on flashlight test, what should I replace? Main board, T-Con Board, Power Supply board or Leds

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
