    LE40A656A1F Dark image in the middle

    Hello i got this TV as a part of a lot of broken TV's , this one works fine but had horisontal lines across the screen. I cleaned the LVDS cable and also the screen cable and connecter , the lines are gone but i have this dark image with weird effect on the left side of the screen as you can see on my video. The connecter which goes to the screen i could not clean because its unreachable atm , i would have to take the whole screen apart. See in pictures. Do you think its possible its T-Con board? How do i preform some tests to rule out the logic board? Also when i bring up the menu , its also dark. https://www.youtube.com/watch?v=qF3EFKYvtHE

      Also if i even touch the ribbon cables the horizontal lines come back. Could it be that the cables are faulty?

          Could be, they shouldn't freakout just by touching them.

              I think its actually one of the ribbons connecting to the panel.. and by me touching the ribbons on the tcon it actually moves the board connecting to the screen... i bet the panel is shot.

                  I ruled it out as a panel problem , i saw some pictures of usual screen failure , and it looks really like what i have on mine. The shadow in the middle i mean. I cannot explain the ghosting on the left side tho, Could be just the symptom of a display going bad. I saw some people hook the 24volt supply on one of the side ribbons that fixed some of the issues like horizontal lines , but i dont think the shadow is fixable , so i just left it as is. Selling it for parts. Thanks for the response tho. Hopefully next one is fixable.

                      Could strip it down a little to get to the tabs, if applying a little pressure on the tabs clears it up, it could probably be shimmed. The tv/monitor I'm looking at right now was shimmed a couple years ago, had the dark/shadow/ghosting going on too.

                          Hi guys
                          I'm trying to fix this laptop screen

                          Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

                          OK so I have the original screen which works but has lines across the bottom quarter of the screen

                          I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...

                          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen

                          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...

                          Hi,

                          I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                          LG 55sk8000 plb ..snow in the middle of screen but can see that picture exists there
                          by burbutsalos
                          Hello everyone.

                          I have this TV set which has this issue. It shows a vertical bar im the middle of the screen.
                          The panel has 12 cofs and the problem seems to be on the territory of the first cof on the right side.
                          The tv fires up and you can see a good picture exept that vertical part where multicoloured pixels exist.
                          The strange thing there is that you can see behind that snow that it shows picture but as if there are these pixels in front so you cannot see clearly.

                          The effect is there even on a completely black screen.

                          The screen...
