Chime and Black Screen issue.
Hello Fixers.
First time posting here. I have read so many posts and watched many videos about similar situation.
I know that this MBP15/L11 has probably a faulty dGPU, but i would love to try to have a solution before to stop.
Tried:
- Reset SMC, NVRAM/PRAM, no changes.
- Removed battery and SSD, no changes.
- Replaced the RAM sticks, no changes.
- Disconnected everything and connected again (on the Logic board), no changes.
Obeservations:
- Apple Logo never turns on
- Display seems totally black
- Putting a light behind i cant see anything on the display
- It always chimes (that should be a good point)
- keyboard backlit never turned on
- Hinges are a bit noisy, not stuck, but sgheeek (soft) noise
So, at this point i am thinking it could be something:
- Keyboard not working/detected?
- Lid sensor?
- Display is dead
Can i start with an USB keyboard connected? Or do i have to find a keyboard and connect trough the connector on the Logic Board?
If the Lid sensor, i have seen i have just to remove the Logic Board and go to check/clean the sensor (that is on the side of the bottom half, right to the battery)?
Any ideas?
Is dit een goede vraag?
