Hello,

I just got this TV and I'm hoping that somebody can confirm what my issues are.
Here are two pictures of what I believe is some bad LEDs in the backlighting:

And here is a video of the screen. On the right edge the content seems to linger and then fades slowly. Not sure if this is considered ghosting. What is the likely cause of this?

The TV is a Vizio E70-C3 (70" LCD). Thanks for your help!

Of course, you may want to disassemble panel and observe them first.

Thanks. I saw that product and I'm pretty sure this would fix one issue. I'm more curious about the smudges on the right edge.

I've seen bad T-cons that behave that way.

Thank you! Looks like they are really cheap to get. I just don't want to put money into this thing and then not being able to fix all issues.

So I exchanged all the LED strips (didn't have any means to test them) and the shadow/dark spot is unchanged. Any ideas?

(haven't been able to replace the T-Con board - should be here Monday)

Thanks!

No dice. Absolutely no changes with the new T-Con. I'm about to give up.

What is the chance of the mainboard being the problem? The only other thing I can think of are the boards hardwired to the panel. In that case it'd be a loss I guess.
