    Lg

    Hey guys I have a LG flat screen I got from my boss from Christmas. When I got it home and plugged it in it had flickering horizontal lines. I asked my boss about it and he said it would usually do that before it warmed up. It does it on all channels and inputs. Sometimes when I turn the TV on the screen will light up but still be black and I can hear sound but no picture. I don't know if the problems are related but is there any ideas on how to figure out exactly what part needs be replaced. I also considered maybe when I moved it I just shook something loose but idk any help is appreciated and thank you in advance. Also I included a screen shot of the lines since I could not upload the video. They just flicker and the more vivid or brighter the picture the worse the lines are.

          You should give more details about the TV, the model number, open the thing up and take good pics of the boards. That will give you better responses.

              Exactly.

              We need clear pictures of inside the set, One of the entire layout and good shots of each board in the best resolution you can so we are able to read any print on them.

                      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...

                      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...

                      by kdaniel
                      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.

                      Sony KD-55XG9505 lines on screen problem
                      by Chrissygizmo
                      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...
