Customer Question

I have a Vizio 47" E470i-A0 0500-0614-0270 LED LCD and I am powering on the TV and the power light goes on which is a white color and then turns off. The TV itself never powers up on the screen. I have replaced both the Power board and the main board. What else can it be?

Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.
Unplug connector from power board that goes inside display panel (backlight connector) and turn On the TV.

Does TV stay On with black screen and do you get sound from TV speakers?

Thanks.

The TV did not work after unplugging the connecter from the backlight

Sorry to hear that, did you get identical replacement boards having same part numbers as of old?

Customer: replied 9 months ago.
I did
Expert:  Shahid replied 9 months ago.

OK, only thing that comes in mind is wifi board or remote sensor board could be short and causing the TV switch Off, it is small board that would be mounted on lower panel where remote sensor board located, it needs to disconnect one board at a time to see if it helps.

Please reply back with the result.

Thanks.
