Re: Vizio D58u-D3 failing leds, seeking strips or leds
I did see that video. Though i was concerned because it showed them fixing the tabs on the lower address bar, which gets fed from the Tcon board. This vizio simply has Tcon board to bottom address bars (left side and right side), then 8 ribbon tabs on the left and right sides (which have not physical chip board....

I am definitely going to use your "peel from both sides" approach to hopefully eliminate any part of the ribbon tearing.
Would using a hair dryer to "warm up" the tab connections loosen or is that heat not hot enough to do anything?...

Also, not sure if you can see it on the pictures of the side tabs...on the Vizio there is not side address bar. So the side drivers dont appear to be connected to anything. It almost likethe tab is integrated into the panel somehow.

On the good side, I haven't really done anything with the tabs or black protectors. I will confirm, but those should still be ready to go.
This is my last shot. If this doesn't work, the TV will be out at the curb next Wednesday morning....

Re: Vizio D58u-D3 failing leds, seeking strips or leds
Thank you for your insight.
I am going to attach some additional images of the screen and side tabs.
I couldn't inspect them under magnification, BUT i took pictures of each one with my good Nikon camera and zoomed in on the ribbons...I could not see any concerning marks or areas. I removed the black plastic tab covers from the bad side.
When I tap the exposed side tabs or press them, I get no change to the image.
I have also took a picture of the bad side address...

Re: Vizio D58u-D3 failing leds, seeking strips or leds
I will be honest, my knowledge of TVs and electrical configurations like what your PDF discusses just is not there. So forgive me if I ask what might appear to be stupid or redundant questions with inaccurate terminology.
So in your experience you have physically removed tabs on one side of a TV panel and it still worked? Or is that not what you meant?
So it is possible that it could be one of the tabs on the "good side" causing the issues on the far side? Because...

I have visually inspected the side tabs on the bad side and did not see any cracks or "kinks" on the tabs. Honestly, I didn't look at the good side. I do not have any tool I can use to inspect them under magnification.
As for the TCon ribbons, I have taken them off and also inspected them. They look in great shape as well. I have also ensured those 2 ribbons are seated fully....

Re: Vizio D58u-D3 failing leds, seeking strips or leds
Makes sense that the added load is causing stress on the good side which probably accounts for the horizontal lines.
I have pressed, jiggled, gently flicked all 8 of the "bad side" tabs. Nothing I did improved the image. I didn't apply any thermal padding, because I didn't see any response from me touching them so I thought id just return it and get my $28 bucks back.
Those "tab protectors" are installed on the panel frame. So when installing the panel you actually...Last edited by dragonsbb16; 01-10-2019, 10:37 AM.

I have disconnected the left Tcon ribbon and it seems there is still a darkening fade occurring even past center.
I have also just notice some horizontal sections or lines in my image. I didn't notice those earlier.
So what might all that indicate?...
