    What causes these vertical lines? LNT4066FX/XAA

    Hello.

    I picked up this Samsung LNT4066FX/XAA over the weekend and when plugged in it displays colored vertical lines all over the screen. Sound is OK. Would this be a T-CON board typically? I would assume so since we have sound and backlight are ok..any suggestions are much appreciated.

    Thanks!
    Joe

      Have you opened up the set yet? On these models typically bad caps on the psu would cause this problem.

          Also could be bad panel too, I have a Samsung sitting that has this affliction with a good working PS and T-con.

                  Screen Display Vertical Multicolor Lines
                  by Stanley1843
                  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...

                  First. it has no picture at all. i solved it by covering the ckv lines using tape to to block the connections

                  Second. now has picture but with vertical lines that follow the image. tcon board ic overheating

                  tried blocking LC lines too, but same results

                  Sony KDL-40V3000 - Vertical lines
                  by gpo23
                  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...

                  vizio e65 e3 LED tv color vertical lines center tv only
                  by viking509
                  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...
