    Re: Vizio P42HD (Plasma) 2 Vertical Lines

    This is a common problem with this panel. The cause is a bad logic board. It is situated behind the main board. It is usually bad solder joints on the main processor and the resistor packs and buffer chips along the bottom of the board. The processor is BGA and will need to be reflowed. You can purchase a new logic board but they are fairly expensive ($80-$100) and the 6871qch038C is prone to this problem. The 6871qch060q is an updated version but it is almost impossible to find new. Replacing either of these with a used board will cause the "sparklies" which LG Panels are notorious for.

      Thanks for the info randtek. How likely do you think a reflow would be to fix this?

        Screen Display Vertical Multicolor Lines
        by Stanley1843
        Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

        Vizio E70-E3 Two white vertical lines
        by brad2157
        I picked up a Vizio E70-E3 for free that shows Vizio logo and then goes to a black screen. Original owner said he started having wifi issues and then he tried to reset the TV and that's when it wouldn't boot up any longer after his reset attempt. I picked up a replacement main board from eBay that matches the same model # board as the original from the TV.

        Original main board - Shows Vizio logo when TV powers on, then goes to black screen. Doesn't boot up. No screen issues with any lines on start up Vizio logo.

        Replacement main board - Boots up fine, but starting...

        vizio e65 e3 LED tv color vertical lines center tv only
        by viking509
        I recently replaced the led backlights with LB65041 LED Backlight Strips and after putting it back together the backlights work but there are only colored vertical lines only in the center of the tv. I can see the Netflix logo (jumbled) after a minute or less the screen went dark. When I turned it on again the lines were back. Then I replaced the t-con board but the same vertical lines in the picture. My question is what is my next step? Could it be a source tab bond issue? A buffer board issue? Could I have loosened a connection to the panel when replacing the backlights? Should I replace the...

        Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
        by howardc64
        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.



        Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

        Samsung Plasma TV with vertical lines (model PN50B430P2D)
        by afex
        This is my 2nd broken TV I'm trying to fix and haven't been able to figure out... currently going without any working TVs so am hoping to be able to fix one..

        This Samsung PN50B430P2D Plasma has this big block of vertical lines which will fade in shortly after turning the TV on. The lines will sometimes flicker a bit or fade in/out and sometimes it just stays present. The length of time it takes them to appear varies, sometimes its a few minutes and other times it appears immediately after powering on.

        I have attached an image of the TV with these bars displaying....
