Question about Vizio Televison & Video

1 Answer

E550i-b2 Vizio TV. It has sound and picture. However the picture is very dark on the left side of the screen... approximately 1/3 to 1/2 of the screen. Tapping the frame seems to make the dark areas shift around a little or either make it temporary worse or better. Any help is much appreciated.

    If you haven't already done it remove the back...test the voltages at the LED driver power supply terminals and see if they are all the same, I think you will find one of them that is lower than the others, I didn't pull the manual on your set so I'm not sure how many outputs you have, could be as few as 2 or as many as 6 but I think this model has 2 of them. If you see a variation in the voltages try removing the connector and use some jumper leads and change the 2 around so the left one is on the right, right on the left and see if the darkness goes to the other side of the screen or stays, if it shifts then you have an issue with the power board if it stays and I think it will your going to have to replace some LED strips in the panel to fix it...Good luck

SOURCE: Dark screen at top of TV picture

If this is a projection set then a center channel speaker sitting on top would have no effect.

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

Vizio 55 inch TV "Vizio E550I-B2" is Darker on the left viewing side, replaced the Power Supply board. And the Screen is still dark on the left side. Any suggestions?

It is a common problem for this TV, it uses a Sharp LED display panel. The problem is the data buffer IC inside the panel ether shorted, or burned open.
Vizio offers a extended exchange warranty if you have the original sale slip.
