    Ok, I'm finally seeing the test points.

    What dcvolts should they be? all the same?

        Well, I know you didn't ask for VDD, but I wanted to measure it for sugar & giggles. Few seconds after testing VDD the TV turned off by it self... I was testing it screen down on the floor... It turned off about 3 more times, ON for only 35sec at a time. Then I stood the TV upright and now its working fine...

        I tested the VDD again, but the TV is not shutting down anymore.

        VDD=16.17
        VCOM=7.48
        VGH=initially 12.67 went up to 13.30 and stayed there (are these values depended on whats playing on the screen?)
        VGL=7.46
        VCC=3.297
        VCC1.8=1.800

        Thank you budm

          Well, now its shutting down again every 36sec. while laying flat on its face... I know small home heaters have a shut off built in but do TVs have something like that also?

            I retested DCV for fun:

            VDD=16.13
            VCOM=7.48
            VGH=13.05
            VGL=7.45
            VCC=3.299
            VCC1.8=1.799


            TV is still shutting down by it self every 37sec...

              If the T-Con board is bad, does the number on the sticker on back of T-Con board must match the replacement?

                Re: Vizio VO370M-C Vertical Lines

                VGL should show as negative, so is it 7.45VDC or -7.45VDC?

                    Re: Vizio VO370M-C Vertical Lines

                    I know it very well may not be the T-Con board, but if I want to buy one.

                    On shopjimmy.com the one has the same part number as mine but has less components on the board, will that board still work in my TV?

                    My partial p/n on back is 1579A, so the part I am looking for is 6871L-1579A?

                    Thank you,
                    Gene

                          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 doesnโ€™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...

                          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.

                          by Daren87
                          Hello everyone,

                          I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

                          Sony KDL-40V3000 - Vertical lines
                          by gpo23
                          Hello,

                          i order a t-con because i had bad colors on my SONY KDL-40V3000 :




                          With the new t-con the color are good but there are vertical lines on all the screen :




                          I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)

                          Is there a way to fix the vertical lines on the new t-con ?

                          Thank you for your help
