Customer Question
I recently moved so...

I recently moved so I wanted to reset the picture adjustment for a new room - I reset the picture mode (from back-lit) to auto adjust. Exited the menu and now I have a vertical green line in the middle of my screen.

Technician's Assistant: OK. To minimize me, please click the down arrow at the top right corner of this box.

Not sure what you mean - the down arrow at the upper corner doesn't do anything but show more options that aren't relevant to my issue

Technician's Assistant: What's the model number of your TV? How old is it?

M401i-A3, purchased the end of 2013. I've had no issues at all so far...I made a settings adjustment moments ago, now the green line?

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

Yes, the menu works...I just went thru a reset procedure, nothing changed. I have Apple TV, and an Oppo Blue-Ray/DVR (which I don't use for Netflix and/or only play audio CD's). I can test the Apple TV source

Technician's Assistant: How long has this been an issue? What happened right before this popped up?

Absolutely nothing...less than 60 min ago I decided to reset the picture screen/brightness mode for the room. I exited from the set-up, looked up and green line appeared

Technician's Assistant: OK. To minimize me, please click the down arrow at the top right corner of this box.

I'm not sure what you mean?

Technician's Assistant: Anything else you want the expert to know before I connect you?

I don't think so

Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, please post back with clear pictures of the screen showing these "...vertical green line in the middle of my screen...". Click HERE.

These pictures would then serve as common reference.

TV Technician: Louie, Technician replied 11 months ago

Appreciate the pictures.

Have you tried unplugging (again) for an extended period of time?

The idea is to simulate a soft RESET and dissipate residual power.

Thereafter, try again but plug back in into a different outlet.

Okay, I'll do that - it's just shy of 5:30 PDT, how long to you recommend leaving un-plugged. Using another outlet source is going to be a challenge - I'm running all my AV equip through a power center/scrubber (should I shut all of my equipment down perhaps?)
TV Technician: Louie, Technician replied 11 months ago

The longer the better since the it is also aimed at dissipating residual power.

Even if just for test purposes, plug back in directly into a different outlet; with no "power center/scrubber"

Customer reply replied 11 months ago
fyi - mark time at 5:30 - I'll restart my TV at 6:15 PDT
TV Technician: Louie, Technician replied 11 months ago

Yes please.

Customer reply replied 11 months ago
I just plugged in my TV (to a remote outlet) & turned it on - the line is still on the screen.
TV Technician: Louie, Technician replied 11 months ago

Then it would be an internal hardware issue.

The prescribed approach is to open up the TV and reseat the LVDS cables.

Hopeful workarounds would be:

  • unplug longer;
  • reposition the TV;
  • gently squeeze the edges/sides of the TV.

Please post back how you would want to approach this and/or should additional information be needed.

Customer reply replied 11 months ago
Okay, thanks for the input. I'll do more troubleshooting from this end and also contact VIZIO support. Appreciate the troubleshooting attempt.
TV Technician: Louie, Technician replied 11 months ago

I understand.

I realize that the above information may perhaps be not what was expected. Unfortunately, I suspect that there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
