    46" Samsung UE46B7000WW LED TV - vertical lines issue

    Hi all

    Got a 46" Samsung UE46B7000WW LED TV with vertical lines running down the screen (see attached). Could this be a main board problem ?

    Many thanks

    Intermittent? Permanent?

    Try blindly accessing service menu:

    (From Standby: Info Menu Mute Power, wait for set to power up)

    Access Control > Test Pattern. (You need to find another TV or a picture of the service menu to know which entry this is unfortunately.)

    You have three pattern selections (press left/right to move through each pattern, up/down for each generator):
    - FBE Pattern Sel: This is the main board pattern generator, the OSD is added on top.
    - FRC BeforeDDR: This pattern is generated on the t-con before the FRC converts the video (50Hz -> 100Hz, etc.)
    - FRC AfterDDR: This is after the DDR is used to process the video for the FRC.

    If the fault exists only on FBE Pattern Sel: main board
    If it exists on only the BeforeDDR or AfterDDR: t-con board or panel

        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...

        Thin stable coloured vertical lines on Samsung UN65NU6900FXZC come and go
        by polaro
        Greetings,

        I've bought a used Samsung UN65NU6900FXZC LED TV. It worked fine for some time and then developed, at first, a single very thin (1 pixel) vertical stable blue line, from top to bottom, close to the left edge of the screen. Now it's 3 lines on the left. When I connect HDMI sources the number of the thin lines grow. After disconnecting and cold discharging I am back to 2 lines. The lines disappear at a rate of 15-20 minutes per line. So it does not look like a damaged LED panel. Any advice? Thanks...

        Samsung 55" UN55JS9000 - Pink vertical lines due to chipped LCD panel?
        by Anonmis
        Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.

        The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly...

        SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
        by JJAAMM
        This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

        Problem
        TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
