Question about Protron PLTV-26 26 in. HD-Ready LCD Television
The easiest way to check if the backlight inverter is working is to look for a dull glow on the screen. Turn on the tv and darken the room see if you notice a dull glow on the screen. If you do then the inverter is functional and what you have is most likely to be a faulty t-con board also known as video driver board or timing control board. Usually costs under 75$ for a tv of this size.

That's the problem with LCD TVs, about 4 things can cause that problem. do you have a volt meter? If so you most inverters get 24v from the power supply. If you don't have 24v that would point to the power supply. If you do have it then the main board would the most likely suspect as there is a "back light detect" line if the main fails it may not see this signal. Otherwise the panel itself is bad and it would be cheaper just to buy another TV at that point.
