    Sony Bravia KDL-46S4100

    I have this very TV set, sometimes it displays 2 blue lines at the bottom, I've noticed it only happens when a TV channel is 720p, will never happen on 1080i channels. Also when a PC is plugged via the VGA input, sometime those lines will appear.

    If I turn the set off and then on, the lines disappear and won't reapear again. It only happens once and not on every turn on.

    Also, when using the VGA input, if I turn the TV off and then on, I get some green flashing that is kinda hard to notice but it's there. Again, turn TV off then on and it will not happen ever.

    The blue lines I've ruled out it being a display issue, because when I display a resolution of 1024x768 on the screen and the picture is centered, sometimes those blue lines will appear on the bottom of the centered picture and not on the bottom of the screen itself.

    Everything 1080p displays perfectly, be it blu rays, consoles etc.

    This display was given to me by my employer and it's obviously out of warranty. I was considering doing a firmware upgrade but I'm hesitant since I don't know if I'll brick the TV.

    Any one have any thoughts on my minor issues?

      I wouldn't rule out panel failure yet, though you didn't provide an image of the issue yet.

      Perhaps try a factory reset. Maybe you have some odd issue with the main board.

          I downloaded the firmware provided in another post on these forums. But I'm hesitant, is there any danger of bricking the TV? Should I just leave the firmware that the TV came with?

          The VGA issue stopped altogether, the pair of lines on 720p TV channels rarely appear and as I said disappear as soon as I power cycle the TV.

          I opted to leave the TV unplugged and only plug it when I'm going to need it, it seems this helps in the issues not appear most times.

              SONY BRAVIA XBR-55A8H - White horizontal lines / red LED flashes four times
              by thstuff
              This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.

              Thread https://www.badcaps.net/forum/showthread.php?p=1091829 helped in proceeding as follows:
              1) Unplugged, then plugged set in while holding the remote VOL- and Power to factory reset.

              2) Waited 30 seconds, then pressed remote Power button and "Select language"...

              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,

              Sony Bravia KDL-40V2500 that will not power on
              by PopsCaps
              I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
              I do not hear any sound and I cannot see any backlight.
              I have tried disconnecting every cable on each board one at a time to see if anything changes.
              The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
              My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...

              Sony KD-55XG9505 lines on screen problem
              by Chrissygizmo
              Hello again everyone,

              This is my latest mission, to try getting this Sony tv back to normal working order…

              I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...
