    Macbook Air A1466 No image

    Got a bit of a odd one. A1466 Press power and I hear the chime and the screen change shades of black. (with room light off it's backlight) I shine a light through the back and nothing on screen no logo or anything. OK I shut it down and hooked an external monitor to it then started up again and screen is normal but nothing on external monitor. I can unhook monitor and the screen stays on just fine BUT reboot and no video again. I can repeat the process to get the screen on but what would cause this?????
    Forgot to mention that I checked both sides of board for corrosion and anything out of the normal and was the cleanest board I ever seen, looked brand new no signs of anything. Also tried a PRAM and SMC reset and did nothing.

        Check the hall sensor area for the open lid function.
        I think rossmann once made a video on this.

            It was in fact a screen problem.

              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...

              AOC 27 monitor Q27G2WG4 doesn't display logo or image on screen
              by 3D Modelka
              Hello. I have a problem with my AOC 27 monitor, specifically model Q27G2WG4, which I have been using for 3 years. The monitor stopped turning on: when I turn it on, the backlight turns on, the indicator starts glowing white, but the logo on the screen does not appear, and there is no image. However, if I check in the Windows system, the monitor is displayed as connected and working. I tried connecting it via HDMI and DP, but the result remains the same. If I turn the monitor on and off multiple times, it will eventually start and work. However, when the monitor is working, there are no issues....

              Macbook A1466 820-00165A heavy water damage but working with "flashing" screen
              by dbuergi
              Hi all,

              i got a A1466 with serious water damage. I was able to clean the whole board and only found a fuse with a coroded trace. Cleaning and resoldering did the job and the macbook started normal but after some time the screen began "flashing" like turning on and off while the Macbook was still running. I checked the board again but was not able to find the problem until now.
              Any ideas where to look?...

              MacBook Air M1 A2337 Screen Replacement - keeping TrueTone
              by MagJ_
              Hello Everybody,

              I have a cracked screen and want to fix it. Usually, TrueTone will be gone as long as one does not prune open the screen and exchange only the LCD. However, I have seen the following Youtube video https://www.youtube.com/watch?v=MBNqhp6p_ZM, Solve MacBook M1 Pro screen true tone issue from the channel Master Liu, where only two chips called "display control chip" and "code chip" are swapped over to the new screen. I know, it is for the MacBookPro version. Though, I had the hope that it could work similarly for the MacBook Air as well.

              Macbook Air A1466 no backlight no image
              by imcool
              Hello,
              On this Macbook Air A1466 with 820-00165
              I have only 8V on backlight line but no high voltage in boost circuit, I have checked all components like caps and diode and they seems to be ok.

              I have noticed that when macbook chimes after turning on there is no image at all even with flash light,

              I have tried 2 different OEM LCD and still there is no image,
              I see the LCD fades out when i remove power or turn off the macbook.

              I have 2 problems
              1 No image
              2 No backlight, but i have 8VDC on backlight circuit.
              ...
