I have a 32 inch Vizio smart led tv Model #E320i-A0 Lg display # LC320DXE- JFR2. It has sound but no picture. I did the "flashlight test" and I can see a picture when I do that. Thanks Tamira

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

The board that controls the screen ranges from 36 to 90 bucks or so. You can replace it yourself using only a screw driver to take the back off and the four screws holding the board to the chassis.
