    Sony KDL-43W807C

    Hi All
    I have just received this TV at a very good price although it has a fault with the picture ?
    It has lines running horizontally across the top of the picture below this it has a great display.
    I have tried changing the t-con board from a similar Sony TV with the same t-con board but this did not clear the fault !!
    Now what my question is I have as I said scrap Sony TV that is almost identical to this TV it is a Sony KDL-43W809C but this has a severely smashed screen.
    Now I have already removed the LCD panel from this TV and have taken some pictures of the two circuit boards that are attached to this LCD panel.
    As you can see each board is attached to the panel via three computer ribbons they are actually soldered on would be more simple if they were clipped !!
    The question I am asking is if I were to expose these boards on the faulty picture TV and used my solder heat station to warm these ribbons would this cure these lines on the picture ?
    And if this was the case would anyone know which ribbon contact I would need to apply heat to for the top section of the screen.

    Any help much appreciated.

    Please see pictures of faulty screen and of LCD printed boards from smashed screen.

    The tab bonds are attached to the PCB with expensive ACF tape and a very expensive machine.
    Press on the ribbon cables and see which one causes the lines to change.

      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...

      Issue with picture quality of Sony bravia TV
      by CyberPhoenix
      Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,...

      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...

      Need T-Con Advice (Vizio P602ui-B3)
      by Jidis
      Hi all,

      I made a big-ass mess here of my father's beloved P602, and I'm trying to figure out if I should order a batch of overpriced ribbons or if I'd just be throwing more good money at the bad.

      He woke up recently to a bunch of white bars going down the right side of the screen. From what I'd seen in these places, I figured the T-con board has gone out or has a bad connection. I took the back off and gently poked at the socketed ribbons and sure enough, got the image back. It was mainly the far left ribbon, and it would snap back to stripes if I let off the pressure....
