    Apple Cinema Display 30 Green Lines

    Hello, i have this apple cinema display 30'' LCD screen, the STA-1 version (first version) that has an issue with lines of green pixels, on darker areas. It's not constant, but it's rather annoying.

    I've replaced the main lcd cable (the bigger cable) and changed the video card on the pc. The issue has remained...

    Would it be the TCON ? I THINK i've changed it a while ago to check if it would still do it, but i might re-swap it to confirm. Can it be the panel by itself that's going south ?

    If i change the resolution to something lower, 1280X800 or 1920X1200, it goes away instantly. It just appears when using native 2440X1600. When switching resolutions, problem goes away for a few seconds or minutes, then comes back. This one, i have no clue so far..

    Thanks for any input, vincent

      You say it works fine, indefinitely, at lower than native resolution? Then it's not the panel, not the t-con. Only the main board can do that. A T-con or panel defect will manifest itself with all resolutions, because by the time it gets there, it's just "dumb" signals driving a bunch of pixels.

      If you say the problem goes away for a little while after you switch resolutions, sounds like something that is overheating and cooling down for a bit when you do the switch. Try spraying various components of the mobo with freeze spray and see where that gets you.

      A working TV? How boring!

          Hi there, well it's instantly going off if i switch to a lower resolution. When i posted this yesterday, monitor was on for hours, then switching to lower res instantly got rid of the pixels. If it was heat, it wouldn't do it instant.. I think !

          Like right now, it didn't come back. It will eventually come back.. But since i switched the res, no signs of weird pixels.

          So, main board still ? I think it might be heat related also.. I have some 4mm thermal pads that i could use on the mainboard's hotter parts, i might try that.

              Well, just for the matter of feedback, never fixed this and this is a common issue. Most of the ACD 30'' STA1 (older rev of the boards) will do this after some time, and never found a way to fix it, other than just switching res.

                  Apple Watch Charging Controller Schematics / Boardview - 820-02601
                  by a_p3rson
                  Hi there,

                  I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.

                  You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
                  This daughterboard uses an interesting...

                  LCD TV Green/Pink screen problem
                  by jimjoe123
                  I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

                  Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

                  Then each time...

                  Samsung LA46A950 aka. LN46A950 - intermittent vertical green lines / distortions
                  by 265chemic
                  Hi All,

                  I have a Samsung LA46A950 that intermittently was displaying issues with evenly spaced vertical green lines only on dark / black areas - this has progressed to more often and blue lines sometimes, as well as a little image distortion.

                  My initial suspicion was the T-CON board, which I took out and cleaned but the issue persists. A heat gun on all of the control boards makes no noticeable change. Ive also reseated the T-CON to panel ribbons (4 of them) and moving them while the panel is on doesn't seem to change the issue.

                  Below are some photos...
