    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...

    Dell U2518D strobing/flashing with vertical lines
    by atticus_
    Hi all,

    I dumpster dived a 1440p Dell U2518D screen the other day and figured I'd take a crack at fixing whatever issues it may have. I powered it up to find that even with no signal input the screen flashes rapidly when turned on and has vertical lines across it. I disassembled the monitor and took pictures of the 3 circuit boards inside it along the way.

    The three circuit boards are labeled "power board l6256-1m", "LED Driver BD L6257-1". and "Interface Board L6127-1". if anyone has schematics for any of them it would be much appreciated...

    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

    1/3rd of screen black with occasional vertical lines - repair attempt for learning! - Kogan KALED58RT9220SVA
    by Firentiosi
    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...
