The screen had thin vertical colored lines. This problem was fixed by replacing voltage controller U9(RT9164A) on the t-con board.(lc420wx7)

Re: Vizio vw42l thin vertical colored line
Moved to TV/video source troubleshootingI love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Hi all, I tried searching the site for answers but I'm a bit over my head understanding some of what might apply and what doesn't, so please be patient with me. I used Freakaftr8's fix to remove the left driver board to restore picture to a black screen with sound Vizio E701i-A3. After doing so, I now have a large red vertical stripe down the center of the screen. The fix did require getting another t-con board from online, I ordered it before I knew about the mosfit fix for the old t-con board. I have tried cleaning the cable connections to the t-con board. I swapped the cables going from...08-19-2025, 06:11 PM -
Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.

I am trying to help my friend to fix his Vizio tv with a vertical line on the screen. The line is on the right side. It is blue/purple on the right side starting from the top. But it only goes to about 3/4 of the screen height (not to the bottom of the screen). It is very obvious when the screen is dark and it is hard to be seen when the screen is bright. Please help.... -
My Father called me he has a Vizio E60-c3 that's probably 3-4-5 years old but it has a thin blue line running down the center of the screen (photo) I tried a couple things but I'm sure one of you all have seen this already. Been a while since I've been here hope all is well. Thank you in advance.... -
Hi all.
I have a Kogan 65' LCD Panel with a thin blue vertical line (top to bottom) on left hand side of panel.
The line just happens to coincide with the end of COF and start of the next COF (attached).
The line is permanent no matter what I've tried. I've tried pressure testing the panel (top to bottom) and all over, I didn't notice any difference with the line, either temporary or semi-permanent.
Also tried unplugging all flex cables, cleaned with isopropyl then re-inserting to no avail - line remains.
Hoping to fix...
