    Guy has a JVC LT-47X579

    1080, but he claims the picture is black,
    with horizontal, multi-colored lines on the
    screen, with no sound.

    He doesn't believe the screen is cracked, but
    who knows what's really there, because
    I've seen cracked screens that gave out
    horizontal colored lines before.

    But it would seem at least the inverters
    and CCFLs are working.

    What you guys think, perhaps T-con or
    main board?

    He wanted $50.

    Good price for just a T-con fault.

      How certain are you that it's only the T-con?

      Also, there isn't much on Ebay for this unit,
      and I couldn't find a T-con there.....maybe
      Shopjimmy?


      I suppose it won't be the end of the world
      if I have to order both T-con and main board.....
      I can always resell
      the unneeded board on Ebay again.

        Not 100% but I've seen it before and it was a T-con voltage regulator.

          You mean you've seen this problem on this particular model?

          Or a similar model?

          I suppose you fixed it at the component level, by just
          replacing the bad regulator? Again, I couldn't find
          a T-con for this one on Ebay.

          Another thing to consider: 47" screen is about the
          limit you can put into the backseat of a Honda Accord!!

            On a Samsung.

            JVC are quite found of using Samsung panels in their higher-end models, so it's more than possible that it's using the same Samsung T-con. You might not find it listed under the model, but it will probably be compatible.

            Yes I fixed it on the component level. Replaced the 30p regulator.

            Biggest car - Peugeot 206 (my dad's) - so essentially a 42" at most!

              Well since he lives close to me, I'll have him deliver it.

              I'll offer him $10, since I may not be able to fix it......we'll
              see if he bites......

                I think it's quite fixable and there are plenty of others who would offer at least half his asking price.

                  Understood, but keep in mind I live in a pretty small city,
                  which isn't very financially healthy at the moment.

                  Case in point: the TV I recently fixed, which I was hoping
                  to sell for around $300 on Craig's, ended up only fetching $220.

                  Economies of scale and all that. So if I can't sell for very
                  much, I certainly shouldn't pay very much either.

                  But you're still right: I'm a cheapie!!!

                    I want to be in your town so I can enjoy monopsony like you do.

                    Yes do bill for your time. I picked up a 42" Toshiba + stand for £50 and I'm selling it for £300.

                      But don't people still give their dead TVs away for free in your
                      town? At least here in Tucson, AZ, dead TVs just get in the way
                      after awhile, when people realize they aren't worth much to
                      anyone except a repair person.

                      $78 for a dead TV? I've gotten to $40, but I'll
                      need to get some more experience before
                      I shell out more than $50 for a doorstop.

                        I wish. I have paid for every TV I have repaired. Usually £1/inch screen size. This is a good approximation from 26" - 47", although the biggest I've repaired so far has been 42" (several times in fact... three plasmas, two LCDs.)

                        Yes - most of them end up at the dump, where I buy them or they get crushed.

                        I have reasonable troubleshooting experience, I think, as well as a lot of equipment. I think I could find a fault reasonably easily, but repairing it is the tricky part.

                          Hi guys

                          I just started fixing 4k TV few months ago. so I am still learning a lot
                          I got this tv from friend complaint is ghosting or horizontal lines on image.

                          never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
                          then it started to show the ghosting white image.
                          I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
                          it has 3 thin small boards at the bottom of the...

                          by ggil44
                          Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,

                          5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

                          I just acquired this 3D LED yesterday and it has horizontal lines on a little more than half of the screen. When I first turn it on it has thin black lines going across that makes the image look serrated, and then shortly after patterns of thicker red lines fade in. If I turn it off and right back on it will reset to just the black lines and the red will again fade onto the screen.

                          I initially thought tab bonds, but flexing the bezel makes no difference, and the fact the image sort of resets after cycling power is different. I haven't opened it up yet to actually test applying...
