    Sony kd 55xf7596 fading picture

    Hi all got a problem with 55 Sony led. Tv
    Model is kd 55xf7596 the TV turns on to a full screen
    Then after 30 seconds or so the picture fades
    Away like a dissolving effect back-light still lit
    I've removed left side tcon flex ribbon and screen stays normal but flickers when the tcon heats up
    So first port of call was to change tcon
    So after. Replacement the TV does the same
    I must stress there is no water damage or panel being banged at all this fault just devoloped

    Any ideas please

      If you can take a picture of the screen fadinng that will help a bit understand what you are looking at.
      But this one is going to be a clear cut case of good ol bad panel with a side tab tear down.
      Remove the bezel, and remove the tabs on the side that is affected. Should clear it right up.

          Merits more testing, one bad capacitor could give the same symptoms.

                  this is Android Set, one of the android TV disadvantage need time to time to clear Cashe as it lager it day after day specially if there much playing with apks.

                  make hard reset ( Not from menu setting menu ) by pressing power and volume - while plug it in wall socket release them after the LED changed from While to green.. also apply update if there available... recommend after any upgrade doing hard reset always the best way to have clean smooth system

                          Sony KD-75XF9005 grey Picture but Sound. TCON or panel?
                          by iglitare
                          Hi,

                          i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
                          Backlight seems to work, Sound (Setup menu after reset) works.
                          If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
                          Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
                          With my small knowledge i would think at least the cables are good.

                          Can this happen because of a bad tcon board?
                          Or is it always a bad/shorted...

                          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...

                          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,...

                          VIZIO E70-E3 Half picture with half TCON
                          by Fly_Among_Stars
                          Hi,
                          I have a VIZIO E70-E3.
                          Symptoms: Black screen, no picture, but LED backlights are working.
                          I probed the power board and voltages are as listed on the board.
                          Main board appears fine, too.
                          I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
                          There are two separate ribbon cables feeding the LCD.
                          If both are connected, the screen is black.

                          If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

                          Fading picture on Sony 48-WD 655 TV
                          by Piotr4509
                          Hello everyone on the forum. Electronics is my hobby, so please be understanding. I got a Sony KDL-48WD655 TV for free, which did not turn on at all from the remote control or the "on" button, after a long search for the diagram, I reached this forum where I found a diagram and a similar case with a person from the forum. Using the hints from one thread, I started the TV by bridging the TPC 8129 source with a 10k ohm resistor. The tv turns on and off, the "+" and "-" buttons aloud also function, which is broken in this section I would like to address later because...
