    A1707 lcd question

    This is not a logic board related issue. LCD was swapped out and verified the good one works.

    So heres the deal, the LCD we have is not cracked, and the backlight turns on. BUT, there is no image on this specific LCD. There is no flexgate because the backlight is turning on. Its just the backlight turning on and the screen is not cracked. I replaced the LVDS connection on the LCD and it still has the backlight turning on. Does anyone have an idea how to repair these in order to get it to display the full image? note the LCD again is not broken or cracked or has the Flexgate issue. I think I see this online as a common issue sometimes in these LCD models. Thanks for anyone that has experienced this and has a solution.

      Backlighting is with 2 lines of interconnect. Hot and ground.

      Video display involves numerous lvds lines.

      This could still very well be flexgate related.

      There is a youtube video where the tech repairs the flexcable that is the root cause but it is not the best solution.

              Suspecting a connector or trace break in the flex lcd cables since a different lcd works. Do inspect the connectors on the non-working lcd.

              Review this lengthy (no pun) process:

              https://youtu.be/A3hUg3KjfYI

              Guessing that the lcd cables can be sourced offshore. Update this thread if you attempt this fix.

                  MacBook Pro A1707 Graphics issue.
                  by janoszw
                  Hi, I'm having a problem with my MacBook Pro A1707.
                  There are graphics glitches all over the screen.
                  I took a screenshot, so it's not a screen issue, but either the graphics card or VRAM chips.
                  Has anyone had this issue before? I don't want to replace unnecessary components.
                  The system is otherwise quite stable, it's just a visual problem.
                  Thanks....

                  Macbook Air A2337 not turning on - ISL or CD issue?
                  by tomtom67
                  Have an A2337 here, which suffered some serious coffee damage. After cleaning C5220 fell from the board, so I replaced it and after lifting the ISL I found pad C5 was also partially corroded, first reballed the original ISL (no power), and then replaced it from a donor.
                  I now get 5V / ~10mA stable on the charger, and found the CHGR_GATE_Q2 (GATE_Q2 on the ISL) doesn't get activated (Q1 does).

                  Is this an ISL or a communication issue (perhaps with the CD3217s)?

                  MacBook Pro 15" 2016 820-00281 no backlight. Another flexgate issue?
                  by slimmy182
                  Hello, I bought this machine from a friend. It's a 15 inch MacBook Pro 2016 model, logic board 820-00281. He said that the screen would go off if open more than a certaing angle but it's perfect working whit an external display.

                  The backlight screen remains stay off even if I open just a little the lid, so I never see backlight work, but I can confirm that LCD show images as using a torch I can see it on the screen. It seems also that camera is not rocognized as the keyboard backlight stay off and touchbar have full brightness.

                  Is this a classic flexgate issue? I...

                  A1707 MBP 15” Battery issue
                  by Stephen
                  Got a MacBook Pro 15” A1707 with an odd issue.

                  Battery is charging, shows normal state 48 a cycles and keeps charging however when we unplug the charger it dies immediately, took the battery out and put it back in and it stayed on then it died again later after 15 mins with it not being plugged in. The battery was at 63% but it's reading normal state and the battery looks good. When I unplugged it and reseated it it started working again. But what's off is it then dies and won't turn on. I'm leaning towards the battery yet it's in normal state condition and charges fine but won't...

                  Macbook a1707 2017 model 820-00928 GPU issue
                  by sofles
                  Hello there

                  I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.

                  I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.
