    LG 47LA620v thin equal spaced lines across screen

    Afternoon all,
    I bought a LG 47LA620v with the fault of it not coming on but with sound, so obviously I head to the tcon board as I have backlight and sound. I had a tcon board for a 47LA575 so popped that in to test prior to ordering a new tcon and the picture comes on brilliant you may think. Well upon looking at the picture there are thin horizontal uniformed lines running across the screen as in pics below. The lines start at the top of the screen but fade further down the screen till they disappear. I then receive the tcon I ordered for it put it in and get nothing but a white line that disappears after 2-3 second of switching the tv on. It also had a main board of a LA575 but I have replaced that with the La620 board and updated firmwares. but it will still only work with the LA575 tcon board. any suggestions??

      Panel failure IMO.

          That what I thought but wanted a second opinion as no one ever wants to believe Panel Failure will happen to them lol.

              I think equal spaced lines are usually board issue
              I assume no responsibility for any stupid suggestions I might post.

                  Not normally, if a horizontal gate driver fails it causes the series addressing of the other lines scanned by the other Ics in the panel to skip rows as well happens alot in Samsungs but double image on sammy panels because they are interlaced.

                                      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...

                                      Hi all
                                      I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
                                      My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):

                                      This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
                                      It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!

                                      So....i don't know what end of the C ribbon to work with...

                                      Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                                      by Ryan.man
                                      Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                                      My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                                      This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                                      As stated by the person I collected the TV from, it just stopped working overnight. However, I still gave it a go to try and repair it.

                                      There is a thread on the same TV but with slightly different issues where they had to tape connection points on the ribbon cable, so I want to see if this is repairable by any chance.

                                      After bringing it home and plugging it in, the TV turned on with its backlight working but had no picture. After removing the back cover, the first thing I tried is to unplug one of the ribbon cables and the situation is as follows.

                                      Left...

                                      Hello again everyone,

                                      This is my latest mission, to try getting this Sony tv back to normal working order…

                                      I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...
