iSight not working and screen brightness not adjustable
Hello guys. I wanted to replace the thermal paste on my Macbook Pro mid 2012 15”, and I proceeded as per iFixit manual.
At first I thought all was good, but after few minutes I noticed that the camera wasn’t working and the screen brightness was not adjustable anymore, just always on 100% or 0% when you go to last bit of the scale.
I tried to reset SMC, PRAM and NVRAM, but nothing. I think it’s an hardware problem maybe?
What part I should check/ change? Is it fixable? The Macbook is working fine, apart from having always brightness at 100% and iSight not recognized.
Thank you, any suggestion is very appreciated!
