    lnt5265fx/xaa few vertical lines?

    Hi
    I have a lnt5265fx/xaa LCD , i bought it for cheap 2 years ago, because it has some colored lines in the left hand side which disappear completely after about 15 min after i turn on the TV.
    Since a few days, when i turn on the TV and wait about 15 min, the lines disappear except one single green line remains.
    To be honest, it's not much of a problem, because the TV is still watchable, but since i have a spare time , i though i would fix it!
    I think Tcon left ribbon cable might be the culprit, but i wanted to have some input from you guys,before i go ahead with my troubleshooting!

    thank you in advance

      Clean them and make sure they are aligned correctly, can use isopropyl alcohol and a q-tip, not too vigorous they can be delicate, good place to start.

          1) What is the brand of this TV?
          2) Attach good clear pictures of the whole backside of the TV showing all the boards.
          3) Attach the screenshot of the screen showing the problem.

              TV is a very old Samsung LCD. Model numbers LNS (2006) and LNT (2007). Vertical lines are panel problems and possibly bad TAB bonds. Time to retire it.

                  One way to find about tabs, strip it down to the tabs and inspect them, try light pressure from the top and see if display clears up, "shim" method may work if that's the issue, many many videos on youtube covering this issue.

                      Sorry for the late update, I've been working on another TV.
                      Cleaning the tabs didn't fix the problem.I also went ahead and checked all the Aluminum caps on the main-board, found few caps with a slightly higher ESR, replaced them, but still i have the same problem.I'm running out of ideas regarding this problem!I think i'm gonna sell it as it is!
                      Thanks

                          insert a metal shim under the cof chip, with a toothpick touch along the chip soldering area, when you found the critical point use the soldering iron to warm that point, at sequential step each time more prolongued, when you are doing watch the results on the image.

                              Is the cof chip, the main chip on the T-con board?

                                          Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

                                          Hello,

                                          i order a t-con because i had bad colors on my SONY KDL-40V3000 :




                                          With the new t-con the color are good but there are vertical lines on all the screen :




                                          I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)

                                          Is there a way to fix the vertical lines on the new t-con ?

                                          Thank you for your help

                                          Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.

                                          The issues are as follows: the...

                                          I recently replaced the led backlights with LB65041 LED Backlight Strips and after putting it back together the backlights work but there are only colored vertical lines only in the center of the tv. I can see the Netflix logo (jumbled) after a minute or less the screen went dark. When I turned it on again the lines were back. Then I replaced the t-con board but the same vertical lines in the picture. My question is what is my next step? Could it be a source tab bond issue? A buffer board issue? Could I have loosened a connection to the panel when replacing the backlights? Should I replace the...

                                          Vertical Lines on Half of LCD Display
                                          by rfxcasey
                                          I have an Siemens HMI with vertical lines on half of the screen. These lines aren't scrambled garbage but rather very regular in pattern and color. I have replaced the LCD with a new one and still the problem persists. I'm wondering if this isn't indicative of a bad video process chip or video memory? Any help would be appreciated. The cable appears to be OK but one pin on the header is unpopulated, though there isn't any loose wire to suggest one broke off or popped out of the connector. In the picture below where the connector is busted out of the side, I did that with my small screw driver...
