A1708 - Problem With Display - Driving Me Insane

[Ado02]

I am working on an A1708 MacBook Pro 13 / Mid 2017 with a keyboard problem. I replaced the palmrest and installed a new battery, which is when the fan started.

When powering on the MacBook, the fan would spin for a few seconds and go off, and nothing would show off on the screen. However, when I disconnected the battery, the laptop would work.

So, I ordered a new battery, but the problem was the same. I spent hours figuring out the problem, but the logic board eventually stopped working.

The next step was to order a replacement logic board - but the same problem was present. So, I ordered another palmrest and battery. The problem is still present.

I even replaced the trackpad and the screen, but the problem didn't go.

Today - I figured out that powering on the laptop first without the battery, shutting it down, and adding the battery resolved the problem. However, I now have a new issue.

When I close the screen and open it again, the screen will not come on. The keyboard backlight is on as normal. When this happens, I must disconnect the battery and go through the same process.

Please help me! Someone must have gone through this and come out on the other side.

Fairly sure this model is linked to flexgate.

Depending on how loud you can yell & scream at Apple, you should be able to get it covered under warranty.

Also demand that they replace the wimpy butterfly keyboard which will give you / client issues.

We have done this with success for numerous end customers - Apple replaced the keyboard assembly & case as well as the display assembly under warranty.

Thank you for your reply. It's not the screen because I have tried 3 differents screens and the problem was the same.

Can you see the graphics on any of the tested display panels ? Use a flashlight / phone torch and view at assorted angles to see if the panel is working.

You have replaced the palmrest which is linked to the lidswitch.

Are you using the same flex cables as the original or were they replaced ?

With power off, carefully review the seating of the palmrest cabling.

You can try without the palmrest connected - remove the cable from the logic board and test again.

What is the voltage of LID_OPEN when the lid is open and the palmrest is connected ?
