    Sony BRAVIA KDL-V40XBR1 Horizontal static lines on screen

    Hey guys, get ready to look at a crap load of pictures, I have a customers BRAVIA KDL-V40XBR1 and the problem with the tv is that there is static like, horizontal lines that go across the screen, each input is different HOWEVER input 7 is fine completely crystal clear.
    also when i push the menu button the menus button comes up completely fine with no distortion
    I believe that the reason why input 7 is fine is because its on its separate board all together . I know its not the panel
    I replaced the main board and no luck.
    I cant find anything online without a dead end answer so once again I come to awesome helpful people of BadCaps forum ...

    this definitely looks to be a mainboard problem. its obvious your panel on your T CON border fine because input 7 works fine.
    Did I leave the soldering iron on?

      In one of the pics is the B Board thats connected to another board ( which i dont know what is ), that i removed from the housing to take a picture of the actual boards itself.
      They are located on the right side of the picture of the back of the tv. (thinking these are the culprit)

          The most important action in the fault - check all the electrolytic capacitors on the ssb board

                    Without this device to talk about the health of electrolytic capacitors is almost impossible

                        Possible without measure, simply replace all the capacitors on the new, special attention should be paid to high heat on the board

                          It is also necessary to include in the display autogen mode, to ensure that no defect in the T-con

                                Re: Sony BRAVIA KDL-V40XBR1 Horizontal static lines on screen

                                I hate to resurrect an old thread, but I'm having an issue seemingly related to this thread. I have a KDL-V40XBR described in this thread. I'm seeing tons of vertical lines and have diagnosed it as a T-CON issue. I searched Ebay and found many for sale (sample) but when I disassembled the TV, I cannot find a board that looks like this. And when I look at the service manual, there is no board that is listed as a T-CON board.

                                Where is the T-CON board on this model? Why doesn't the service manual list the T-CON board? Or is the T-CON board linked above not actually for my TV?

                                Any help would be greatly appreciated.

                                Thanks.

                                    Thanks for the reply. I'm not having the same problem as the issue in the thread with the horizontal changing lines. It's vertical colored lines that show up exactly the same on every source. That's why I figured it was the T-CON board. Is the B board the T-CON board on this model? Or is it a different board and I'm missing where it is? Thanks again.

                                      Vertical static lines are almost always a tab bond (panel ) problem.

                                        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...

                                        Sony XBR-65X750D Horizontal lines bottom of screen
                                        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,

                                        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...

                                        Hello,
