                      Pssh!

                      Its the fricken Zebra cable connecting the very last wire to the LCD panel-The thin cable soldered directly to the glass panel.

                      Try pushing lightly on the plastic bezel under the missing line. Does it get better?

                      Try pushing lightly on the LCD panel. Does it get worse?

                      You'll probably have to actually lay it on its back and remove the bezel around the screen, then push very lightly on the very thin and delicate flat cable connecting the TConn to the LCD. A rubber eraser may be helpful. If it goes away then the solder joints have separated. The only way to fix it is to use a hot air gun or soldering iron to reattach them while pushing down lightly, gently and carefully(basically on the edge of the glass!). Silicon would be helpful here.

                      This sort of job is best left to an experienced professional. the manufacturer uses a long tool that pushes down and heats up the solder.

                        I think the "other guy" was asking for pictures of the back of the set WITH the back cover removed.... :-) so he can see what's happening with the cabling.

                              kinda looks looks like the transmission is set to sbs 3d mode... are you sure the lcd panel tcon cables werent installed backwards somehow?? that or its set to a different panel type in diagnostics.those rca branded sets use the same main baord numbers for many different model tvs with different firmware and sometimes hardware... I had a 50" I repaired give me grief because a seller of the replacement mainboard made and assumption and sold me the wrong board.... you have to be sure the serial number range matches the part number for the board and not just the number printed on the board itself.

                                    In order to properly diagnose your TV we need clear pictures of each board in the back of the set which means removing the back cover. We need good clear pictures of mainboard LVDS cable, tcon board including cable connections going into the LCD panel itself. This could be a fault with the LVDS cable or the tcon board or the main board sending the output signals into the tcon to the LCD panel
                                    Did I leave the soldering iron on?

                                      43UM7100PLB, no picture but have half picture when i disconnect 1 side of panel
                                      by sigmeyer
                                      Like the title says , this is a very interesting problem , never experienced this before so i thought i'd share and maybe get some help on this. So the problem is as such: TV comes on , some gibberish flashes on screen and the screen remains black , the owner of tv said he heard sound. Now i checked some things cleaned all connections first of all so i dont run in a circle. Then i disconnected one of the cables for the panel , and viola, the left side of screen comes on, then i tried to switch it , with left side disconnected and right connected. Same problem persists. I checked some voltages...

                                      T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)

                                      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)...

                                      Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                                      by TR103
                                      Hi, I have a Samsung UE50TU with:
                                      - sound and backlight, but no picture
                                      - when it arrived, it had a picture for a few seconds
                                      - it keeps rebooting
                                      - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                                      - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                                      - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                                      - without cable between mainboard and lcd panel and with a jumpered...

                                      TCL 55US57 backlights, no picture.
                                      by DXseekerMO
                                      So here we go with another screen short TCL. For this exercise left and right will be reference looking at the screen.

                                      The person I got this TV from said the color was bad in a vertical fashion about 1/4 of the way over the left side of the screen. Shortly after the symptoms below started.

                                      Power Supply, main and T-CON board are working.

                                      Symptoms: The TV has backlights but no picture with both FFC's attached to the T-CON and does not respond to the remote or buttons, and the TV appears to continuously re-boot.

                                      Unhook FFC from left side...

                                      I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
                                      Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
                                      when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...
