Vizio 48 Model E470I A0 Black Screen Vizio Television

Chosen Solution

Hello I have a Vizio 48" Model E470I-A0 complete black screen. I did the flashlight test and able to see the picture in the back, but it flickers a little bit between lighter and darker spots. Is this the LED back lights or it’s the power supply. Thank you in advance.

@randym most common error is a failure of the power to the backlight. Check to see if your TV has a separate inverter. If it does not replace the power board.

Turn all lights off in the room and with tv turned on, look through the vents on back of tv. If you can see lights it is not the LED back lights.
