    Vertical lines on a Samsung UN60ES8000 - salvageable or bad panel?

    I have one thick vertical line right in the middle, along with a few smaller lines about 1 px wide of various colors.

    I understand that this is most likely a defective panel? But wanted to rule out a bad tcon or LVDS cable just to be sure there's no hope before tossing it. I've read that this model has a built in tcon test pattern accessible via the service menu, but I wasn't able to see any difference on screen while scrolling through 0-18 of the patterns, unlike the mainboard test patterns.

    My question is: is the screen supposed to change when viewing built in tcon test patterns? If not, how do I verify if the tcon is good or not in this case? I've already tried reseating and shifting the 4 ribbon cables between the panel and tcon around.

    Photos attached of the symptoms. I followed the service instructions in the slide below, but got stuck at the tcon test patterns.

          I've read suggestions online to heat up the edges near the tab bonding boards and apply pressure. Is this worth a try, or is the panel just toast?

              This guy had a bad solder joint on one little resistor: https://www.youtube.com/watch?v=Jsbw5wroTRM

                  New user here... I've done this in the past with about 50% success; sometimes
                  it kills the entire panel. If you're willing to take that risk you have nothing to lose by trying... Good Luck!

                      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...

                      Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
                      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...

                      Vertical Lines on Half of LCD Display
                      by rfxcasey
                      I have an Siemens HMI with vertical lines on half of the screen. These lines aren't scrambled garbage but rather very regular in pattern and color. I have replaced the LCD with a new one and still the problem persists. I'm wondering if this isn't indicative of a bad video process chip or video memory? Any help would be appreciated. The cable appears to be OK but one pin on the header is unpopulated, though there isn't any loose wire to suggest one broke off or popped out of the connector. In the picture below where the connector is busted out of the side, I did that with my small screw driver...
