Grey screen after apple chime.
Hi, my Macbook get a grey screen after chim .
Its happens after i did a upper case swap ( my case was bent). Macbook has no spills or any problems before.
I dont have a mini DP cable to test a video output.
I did memory swap with another Mac- but no luck.
I tried to reset SMC and PRAM- no luck
Also tried to boor in safe mode- same grey screen.
I did a upper case with keyboard because my case was bent.
Macbook boots up and i can adjust brightness of the screen and sound volume
but its only no image on the screen.
mayer, sorry about that my bad
ordered a mini display port cable to check on the external monitor.
No image on external moniror as well :(
I decide to sell it for parts , but nobody want it
Next step is reballing a gpu Nvidia on logic board
