    Lg 55LB700V with vertical stripes

    good night! I pass photos of this tv with vertical stripes. what problem could it be? panel or tcon? the tcon of this model is integrated into the panel. Let's see if they can tell me what to do to see if it can be fixed. the vertical stripes have a certain pattern, because there are some equidistant.

      with LG i never saw T-CON integrated at panel. they are all separated or on Main boards
      if you don't own this Tv then let your finger out... if you have it under hand then open it and post photos of the Panel buffer boards.

        Good afternoon. Thank you very much for your reply. it may be that I was wrong. I meant that the tcon is on the long boards attached to the panel. However, I am sending you a photo of the main board, because perhaps it is integrated into the mainboard. I hope I have understood your request. It was difficult for me to open it because a screw on the base was destroyed. If you see tcon, indicate the zone, and what tests to do, to see if it is tcon or panel. A greeting and Thanks forward


        If you need more photos, I'll send them to you.

            Good afternoon! when trying to open the tv to be able to disconnect the ribbon cables, I have seen a large corrosion in the lower part of the panel, so that is where the problem lies. I'm going to try to clean it up and see if I can save it. I'll contact you again when I've cleaned it up, if you have a solution. Greetings and thank you

              good morning. in the end there was no rust. I have disconnected a flat cable each time, and the result of the photos comes out. There are stripes in both situations, in one fewer stripes. it has a solution?

                      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...

                      Samsung LC32HG70QQUXEN - vertical and horizontal stripes across the screen
                      by kotel studios
                      Hi,

                      Just now my Samsung LC32HG70QQUXEN monitor gave up on me. On cold boots I get many vertical stripes going across the screen (see the attached picture). After it runs for 1-2 minutes those go away but there are horizontal stripes going across the whole screen no matter of the input and PCs I use. (couldn't take an picture of it since the image size goes to 20MB and the camera doesn't pick them up)

                      In a video about a 27" monitor with an similar issue the guy removes one resistor and supposedly the entire monitor goes back to life? For sure this fix is only temporary....

                      MacBook A1990 vertical stripes on external screen
                      by ahoonid
                      Hey everyone,

                      I bought a MacBook A1990 with no screen. I bought it knowing the motherboard was defective but wasn't sure what the problem was until I received it. It actually turns on but as you see from the attachment, it has vertical stripes, on an external screen!!

                      The board is neat. Not opened before for sure. Just a little dust, nothing more.

                      Recovery using wifi can be opened, as can also be seen in the photo but it doesn't go all the way through after connecting it to a wifi. It downloads the initial Recovery files but never completes the rest of the...

                      LG 82UN8570AUD ~ TCON or PANEL?
                      by kca
                      Hello all ~

                      Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

                      When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

                      I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

                      KD-55X9005A Vertical Stripes Right Side Mirrored Vertically At Start
                      by kevinman
                      Hi, TV boots with distorted image right side mirrored verticaly sometimes vertical stripes making off-on turns picture to normal and "perfect" (netflix image) that I highly doubt this is something related with t-con signal lines?? rather it looks software corruption bad mem chips voltage collapse or an intantaneous fault with fluctuating powerboard voltages?? As it happens usually when TV is cold sometimes fault comes back after a full day use should I check powerboard voltages with oscilloscope??
