    Samsung UD65HU7200F smart tv - vertical lines on display

    Hello,

    I am bought a Samsung UN65HU7200F tv from a neighbor very inexpensively. He stated that it just stopped turning on, but the year and a half prior to that, it was great. I replaced the power board and everything worked. However, there are some vertical lines on the screen on the left side (mostly white, some colored stripes), and faint alternating grey/light stripes on the rest of the screen. (see pictures)

    I ordered a replacement T-CON board and installed it. No changes whatsoever.

    I have checked the tab bonding, and on the left side, it flickers when I press on it, but doesn't go away. I haven't found any connection that changed any other aspect of the display. I placed some thermal padding on the left tab (as shown by Bud M-thank you btw), and it didn't change anything.

    I'm not sure what to do next. Could the main board cause these problems? Can the tabs/boards on the TV be replaced?

    Any help is appreciated. Thanks!

          Sorry - I went in to edit and there was no place to add attachments. I've contacted the administrator and as soon as I have that capability, I'll upload those photos.

          Thanks!

              You can attach them to a new post. I'm not sure the admin, Topcat can help you much there.

                      Wow is this out first curved 4k tv repair! !??

                      How about any of the components on the top boards of the lcd screen? Bad solder connection? Try some freeze spray above the affected area

                      To me it looks like a tab bonding issue but the rest of the screen affected may be a result of the affected area. Try just having the opposite side connected to the tcon. Is the grey shadow lines there still?

                      Did I leave the soldering iron on?

                          Wow! 18 months old and failed. Hmm... is that tab bond board on the bottom of the TV? If it is, ask your neighbour if he cleaned the TV screen lately.

                              I would say the panel is failed. Sorry...

                                      Thank you all for your input. I will try freakaftr8's idea about attaching one side of the t-con board, then the other and see what happens.

                                      By freeze spray, do you mean the compressed air cans that you can use to clean dust and other debris out of electronic components/keyboards, etc?

                                      I'll also ask my neighbor about a recent cleaning.

                                      Yes, the tab bond board is on the bottom.

                                      Can the panel be replaced? I'm not totally clear on exactly what the parameters of that part are.

                                      No warranty.

                                      Thank you all for the input!

                                          It looks like Costco in the USA sold this TV at $2179 after a $600 rebate.

                                          If this set was bought from Costco, they generally have a 2 year warranty on the TVs they sell.

                                          I usually never buy extended warranties, but Costco has reasonable prices to extend the warranty up to 5 years.

                                              The "panel" is the 65 inch display, it is not practical to replace it (especially as it's curved) and is likely to cost more than a new TV. Only on certain specific TVs is it practical to replace the panel, in most cases it is not.

                                                  Wow, TV quality really has gone down the toilet these days, hasn't it?

                                                  If it is a tab bond issue, then it is gone I guess. I've fixed tab bond issues on calculators and microwave LCDs with my soldering iron (by just applying heat on the ribbon), but those generally have big traces. I don't think this would be possible here. But I suppose you could try before parting the TV out (if you chose to do that, of course... some people will watch it like that until it gets much worse).

                                                      Interesting... I never knew that Costco has warranty for a reasonable price like that.

                                                          by Falki
                                                          Hello there, ive recently found an older 55inch Samsung SmartTV.
                                                          Sadly it has vertical lines at the left and one line in the middle-right.

                                                          I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
                                                          I have factory resetted the TV as well but also with no luck.

                                                          I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..

                                                          A similar issue has been posted as well but also with no actual response ...

                                                          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...

                                                          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...

                                                          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...

                                                          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...
