Visio E601i-A3 Backlight Can't Post
Good Afternoon Everyone,

I bought a E601i-A3 about a year ago and it has worked flawlessly up until now. This morning I turned it on and half of the screen was black starting from the middle and progressively getting worse. After a call to Visio turns out my warranty ended 2 months ago so it is up to me to fix this bad boy.

I am no TV technician but I have fixed a few in my lifetime. From what I understand TV's usually have a backlight inverter but a search under this model brings up nothing.

I have found:
VIZIO E601i-A3 POWER SUPPLY & LED DRIVER BOARD
AND
VIZIO E601I-A3 SHARP T-CON BOARD

But neither of these looks to be the part I need. Can anyone tell me if this model does indeed have a backlight inverter or point me in the right direction as to how I can go about fixing my issue.

Thanks kindly!
Ponzo

Key TV features:
Display technology: LCD
LED backlight: Edge-lit

The E601i-A3 sits in the features sweet spot for LED-based LCD TVs. Its edge-lit LED backlight ...

NO "Inverter!"

*Facepalm* I actually read that and didn't put two and two together. So if this thing is edge-lit and half the screen is out I assume the LED along the edge might not be the issue.

Do you know if there is a controller of some sort that powers the LED such as the "LED Driver Board" I posted?

Thanks for the response!

That and the boards/wiring to them.

IF all four edges lit (four sets of wires) unplug ones for the sides and make comparative resistance readings. IF each pair of edge LED strips measures the same strips and wires should be OK.
Do the same with the top/bottom strips.

Hopefully not to https://www.youtube.com/watch?v=acI12jO0HSQ

Awesome! That seems easy enough to do with my handy dandy multimeter. I will get the unit ASAP and start going at it.

Appreciate the knowledge
