After reading up on the issue I assumed the problem was in the Tcon Board, so I ordered a new Tcon Board for that model and replaced it, that did not solve the issue and so I tried disconnecting the ribbon cables that connect to the Tcon Board one at a time and after disconnecting the cable which I have circled in the picture below, that sorted the problem out. So my question is, is the problem with the ribbon cable and if it is how do I replace the ribbon cable? I unscrewed the metal bar to which the tin foil in the picture is stuck to but I couldn't see how to disconnect the cable from the place it is connected to what I assume is the panel.&nbsp;</P><P>Thank you so so much for your help!</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="IMG_1102.JPG" style="width: 1200px;"><img src="https://community.sony.hr/t5/image/serverpage/image-id/468560iFAF43F556761D82F/image-size/large?v=v2&amp;px=999" role="button" title="IMG_1102.JPG" alt="IMG_1102.JPG" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="IMG_6254.jpg" style="width: 1200px;"><img src="https://community.sony.hr/t5/image/serverpage/image-id/468561i7093FA473EBD95C8/image-size/large?v=v2&amp;px=999" role="button" title="IMG_6254.jpg" alt="IMG_6254.jpg" /></span></P> Sat, 13 Feb 2021 20:05:49 GMT 99drago 2021-02-13T20:05:49Z https://community.sony.hr/t5/android-tv/sony-bravia-kdl-40hx753-horizontal-lines-replacing-ribbon-cables/m-p/3772130#M52327 <P>Hello everyone, I need some help with horizontal lines in the top quarter of the screen on a Sony Bravia KDL-40HX753.
