    Sony kdl-50r550a. Horizontal strips come every 4-5sec.

    Hello.
    1st of all - thank you for reading this.

    I bought this tv 2 years ago, and for 3 months we travelled with my wife.
    We came homeand found what there is a horizontal lines with slight disturbing in the bottom of the screen. They appear for 1 second and disapear for 4 seconds.

    I dismantled back panel and disabled ribbon cable which connect t-con board with man board (where hdmi inpunts is placed), turned on tv and lcd panel turned on without horizontal strips. connected t-con back again and those strips flickering appeared again on black.

    So my question is next - changing t-con will help me or not?
    Thank you in advance.
    And sorry for my english.

      Horizontal lines for the most part does not represent a T-CON Bd problem. I would think you have a Tab bonding issue. Perhaps if you post clear pics of the backside of your set with the back removed we may be able to offer better help.

          Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
          by noisykid
          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...

          Sony KDL-50W685A horizontal black lines Pattern
          by Raulnn
          good morning! I have a problem with this Sony. The image has a pattern of black horizontal lines, I attach a photo of the lines. The power supply is external and emits a sound. I don't think it's because of that. Let's see if someone can help me.

          Sony XBR65X900H TV with Horizontal Lines right half of screen
          by dvu0627
          I have a Sony Smart TV XBR65X900H that started to have horizontal lines on the right side of the screen (see attached picture). When I played video on Youtube green horizontal line at regular intervals(1/4") across the screen.
          I replaced the T-Con board but the lines are still there.
          I believe this issue is from the Main Board. Before I replace the Main board, I wanted to seek advise if this is the problem from the Main board or something else?
          Thank you for the help....

          LED problem on samsung UE55F6475, 2 strips work. The rest is flashing every second.
          by Kingfreddie
          Ok.. this is the story:
          Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.

          This is kinda how it looked, just that mine were at the bottom of the screen:

          Hisense 65R6E3 double-image / horizontal strips - TCON?
          by jason123
          Hello all. 3 years back, with your help, I replaced the LEDs on this TV. It's been working great. Yesterday, I turned it on (garage TV), and it has blurred horiz / vert lines as you see in photos. Definitely no physical hit or damage. Top 1/6th of the screen is perfect. Could it be main / TCON board? No tabs to cut on this model. Thank you...
