    Sharp LC-70LE650U vertical black and red bars

    Hi all,

    70" LED TV is Sharp LC-70LE650U.

    Initial problem was horizontal lines and slow motion lurrs on the bottom left of the screen. So I removed both the left and right ribbon cables from the T-con board and tried to clean it with alcohol and when I put it back, this issue appeared. I tried carefully reinserting the ribbon bon cables but same thing. I checked the traces of the ribbon cables with magnifying glass and everything looks good. I cleaned the small jumper ribbon cable on the left side of the screen which cured the horizontal line and slow motion blurs but I ended up with this new vertical bars issue.

    One thing to be noted that the pattern is same on both halves of the screen. If I remove left ribbon able from the tcon boars, then left side of the screen turns white and if I remove right ribbon cable then right half turns white.

    Do you guys think I somehow damaged the tcon board? Can bad tcon create similar bars and pattern on both halves of the screen? The exact half of the screen is where the O of Optic is. So exactly same pattern on both halves of the screen. Please suggest. I have already ordered tcon board.Thanks.

      Samsung UN46C8000XFXZA vertical bars/horizontal lines

      I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

      The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...

      TCL 50S535 bad tcon or panel issue?
      by x_orange90_x
      Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

      Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
      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...

      Sharp LC19SB24U; red vertical line comes and goes
      by valvashon
      Yes, this is a very old Sharp 19" but I would like to fix it if possible. As you can see from the attached picture there is a single red vertical line.
      Yesterday when I turned the set on, it was there for about 30 minutes then disappeared and did not show up again (set was on for another 3 hours or so).
      Today it was not there when I powered the set on, then appeared after about 15 minutes. Set has been on for about an hour and it's still there.
      From what I have read I'm guessing that this might be the t-con board and not the display itself as it does come and go.

      T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
      by Tr0ll
      Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

      The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

      Original T-con:
      Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

      First replacement T-con:

      I thought it might be t-con and ordered new t-con from china(supposedly tested)...
