VIZIO 42 CLASS RAZOR LED SMART TV M420KD picture has lots of green ghosting and thin white vertical line through left side of screen also


Hi Charlene,

please try with video input from any device,and i think you are using local antenna and it has gain problem or your tuner section of the tv is not working correctly.
if distroted pictures comes with video input signal it is video amp and processing unit problem.
you have to go for repair shop for fix that.
regards,

Thin blue line


I am a Sharp Servicing Technician. You posted this before. Ive got the same model TV as you do LC46D62U. I think the line you are experiencing is simply the broadcast. I notice it on some HD shows that broadcast the side bars. (Always on the Ellen Degeneres Show). Ive taken some picture.

1) Here's the line on the left that i experience

2) Later on in the broadcast, it goes away.

One way to check if its a TV problem or not. When the line shows up again, hit the MENU button on the remote. If the line appears to be "behind" the menu, then it is simply the broadcast.

If the line appears to be "on top" of the menu or shows right through the menu, then it is a TV problem.

Im thinking the reason it takes hours for hte line to appear is because it only shows up on certain shows or certain HD broadcasts.

Autiovox lcd Half the screen turns blue the other half has virtical lines in it.


Typical of the glue that holds the circuit to the screen coming loose.
it will take a very good repairman to fix this and he will have to know where to find the glue, its special with microbeads embedded.
