Question about Vizio Televison & Video

1 Answer

I Have a vizio E320I-AO 32" TV. The back light and sound have gone. What could be causing the LED and sound to go bad?

LED's are actually dimly blinking in unison. I have changed the power supply board but nothing changed. Flashlight test shows picture is there but LED panel is not backlighting it

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

My screen is flickering on and off on Vizio LCD TV? I was wondering if it was the main board or the T-Con board.


Flickering can be either with the fault to its back-light inverter or with its main power supply regulator board.

I have a Vizio E320I-A0 and it has multiple vertical and horizontal lines on the screen, how do i fix that?


Hi,
Probably the T con board is faulty. T con board is the one which drives the lcd pixels. Chekc the video to identify the t con board. Also try to remove the connection to T con board and reconnect it. some times bad contact on those connectors can lead to such problems.

My Vizio E320i-A0 tv, has barley any picture when i pug in and turn on, VERY faint logo on screen, How do I fix it?


The picture settings may have been set very low. You can reset to the factory default settings using the steps below. You may also try selecting different inputs to see if the brightness is the same on all of them.

1. From the Picture Settings menu, use the
Arrow buttons to highlight 'More' , then press OK.

2 . Use the Arrow buttons on the remote to highlight 'Reset Picture Mode', then press OK. The TV displays, "Are you sure
you want to RESET Picture Settings to the factory defaults?"

3 . Highlight Yes and press OK.

4 .Press the EXIT button on the remote.

A manual is available here:
