    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 doesnโ€™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...

    Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed๐Ÿ™
    by Daren87
    Hello everyone,

    I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

    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

    TCL 50S535 bad tcon or panel issue?
    by x_orange90_x
    Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

    Hitachi LE55U516 - Vertical lines - Not always present
    by jason123
    *** Board Photos here : https://www.badcaps.net/forum/showth...light=LE55U516 ****

    TV Works fine, but there are thin vertical lines (not necessarily all the way from top to bottom - sometimes top to 1/3 or 2/3 of the screen) and these are not always there. They seem to come and go depending on the type of picture, colors,...

    There is no firmware update for this model per the manufacturere.
    I did a full factory reset.
    When I got it, it had bad backlight (a couple of bad LEDs) - fixed these only to find the vertical lines. I Reseated ribbon...
