Chances are its the Inverter. However since the audio doesnt work either its also possible that the main board could be the cause. As in most cases audio will still work when an inverter fails. so its about a 50% for each board when the audio doesnt work either. You can get some free assistance yo help troubleshoot which board is at fault from www.tvcircuitboards.com they should also have replacement boards for your model.

SOURCE: how to replace the backlight inverter board on Samsung smart tv UN55ES6100F?

If you wish to get some details; visit the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
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.

Is it the back light or board thats the problem?
Hi Colton...This model TV had a high level of backlight failure and I'd give you a 95% chance of the backlight strips being bad, what generally happens is some of the lamps short and it drives up the current, the over current section of the power board inverter section shuts down, this is why you see a picture for a few seconds when you power the set on. New lamps should fix it, there isn't a simple way to test the inverter unless you have some higher end test gear and the electrical engineering knowledge to figure what the draw should be and compare it to the draw you see, to complicate matters it's the negative side of the inverter that's regulated not the hot side, also a signal comes from the main telling the inverter to turn on and that can cause backlight issues but like I said with the past history of backlight failure on this model chances are really good your backlights are bad...Hope this helps

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
