    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

    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...
