    LG 42LN5200-UM vertical bars

    Turn on TV, displays these wide vertical bars. Thinking bad TCon, got a new one from shopjimmy. Just put it in, and still doing same thing. Assuming now either bad main board or bad bonding to the panel. Here is a pic. TV was located in an enclosed outdoor porch.

      Looks like a TAB Bond issue. The Main Bd could be faulty as well. Do you have access to an oscilloscope? So we could see if LVDS signals are being output from the Main Bd into the T-CON Bd.??

          No scope. The bars do coincide with using the remote, i.e. no bars when first turned on. Hit menu on the remote, those bars show up. Try to blindly navigate menu, bars change.

              Almost certainly a panel issue of some kind.

                  Samsung UN46C8000XFXZA vertical bars/horizontal lines
                  by x_orange90_x
                  I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

                  The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...

                  Sharp LC-70LE650U vertical black and red bars
                  by ninja_zx11
                  Hi all,

                  70" LED TV is Sharp LC-70LE650U.

                  Initial problem was horizontal lines and slow motion lurrs on the bottom left of the screen. So I removed both the left and right ribbon cables from the T-con board and tried to clean it with alcohol and when I put it back, this issue appeared. I tried carefully reinserting the ribbon bon cables but same thing. I checked the traces of the ribbon cables with magnifying glass and everything looks good. I cleaned the small jumper ribbon cable on the left side of the screen which cured the horizontal line and slow motion blurs...

                  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 Plasma Intermittent Vertical Bars (repeatable) PN50B430
                  by JesusJones
                  Trash picked this plasma for parts and found it had some bad solder joints. It powered on after reworking most of the boards and seems like it may even work.

                  The symptoms is, when showing a picture of bright (mostly white) intensity (within the affected area only) a vertical strip 2 3/4" wide will begin to fuzz out (just to the right of samsung logo, 16 3/8" from screen edge), and soon turns black (from top to bottom). Changing to a darker scene immediatley ater will cause the black stripe to fade back in (it fuzzes and clears up again) and it starts working just fine....

                  No Ringer Sound in Intercom outdoor panel (Voice Communication Works)
                  by salah11
                  Hello everyone,
                  I have a persistent issue with a commercial intercom system (likely made in Turkey, based on the unit). Voice communication (audio) works perfectly, but the outdoor panel did not return the ring when the call button is pressed.
                  Whell the system consists of three main circuit boards (see attached photos):
                  A. Board 1: Power Supply / Ringer Generator (White Board) with LS1240A, BD442 and BD140 Power transistors for ring amplification.
                  B. Board 2: Handset (Indoor Unit) Role: Contains the microphone, the speaker/baffle, the manual hook switch, and the open-door...
