My TV looks like the one above, it is Vizio E70-E3. The 12 LED backlight strips appear to be controlled in sections of three Strips (each strip is 10 LEDs of 3V DC apiece). The pic above shows the lower right quadrant failing (one section of three strips). On my TV it was lower right and then a month later the top right also went dim.
Important - the dimmer strips appear to be working still, but they are just dimmer. If I use the "backlight" adjustment I can see them working but they remain about 50% DIMMER than the rest of the TV.
When I look at the main power board I see there are 4 LED voltage control outputs (indicating four sections as I said).
But what I can't determine is whether it is the LED strips or the power board which is bad, or maybe even the T-Com board. It has been really hard to find information ion this specific problem online.
