    LG 46ld550 screen issues

    I have a LG that as you can see in the photo has a scrambled image, my first thought was the tcon board. After I disconnected the hdmi cable it began displaying the LG image and it slowly moved across the screen. My question is, can it still be the tcon board even though it displays that image perfectly. I tried it connected to a tablet, a cable box and an Xbox, none worked. Thanks for your time

    After fooling around with this set it has magically started working perfectly. Go figure. Anyone have any ideals? I can find no bad caps, visually. Has anyone experienced something similar? Once again thanks for any input.

      Update, it still has the scrambled picture when I first turn it on. After being on for a few minutes it slowly clears up. Can anyone steer me in a good starting direction.

        Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

              I had a 42 version LG where my picture on the screen would play up but i had to warm up the BGA on the main board with a hairdryer to make it work

                They look like their pretty much the same board. I was hoping someone had identified an easy fix for his but after a day or so with little action on the thread I realized I wouldn't be so lucky. Usually heat is the devil for these things. Thanks for the input

                      Thanks, but what do mean by "reflow" the bga? Does that mean get a new main board?

                        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...

                        M1 A2338 screen and touchbar issues after cleaning up liquid damage
                        by jkruns
                        Hello everyone,

                        This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

                        My patient is an A2338 Macbook Pro M1 (late 2020).

                        It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

                        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...

                        Macbook Air M2 A2681 Kernel panics after screen replacement
                        by reformatt
                        Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

                        It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...
