Broken Hinge with unibody MacBook air

Thanks for your reply Rany, I'll do it. The Technical Support is supposed to have done the same. They said that changing the part (I think the black one) below the display frame could damage the screen itself.

I don't trust them. So, is the golden part under the red circle in the last pic the hinge? Could I fix or change it without compromise the black bar? I can't find replacement hinges are on sale?

Sorry these are a lot of question, thank you for your support!

In step 25, the hinge appears to be golden (visual effect). That's the part that may need tightning or replacing. In addition to the steps in this guide, you have to slide the U-shaped black plastic cover (that U-shaped plastic piece can seen in picture 27 under the superego/tool they're using). So you slide it towards one of the hinges by about 1 cm, then proceed to lift it up. Underneath it, you can find where the hinges attach. Sometimes you can fix the issue and/or replace the part, and sometimes not, depending on what's wrong. You won't be able to tell until you go this far in tearing it down. Be very careful when handling the screen as you may very easily brake the LCD indeed. Don't lean on it or flex it.

Hi, I followed the steps but I can't see any broken or strange thing where the hinges attach. Could I send you the photos in some way?

@minnabella post them as un update to your question. Mayer included a link below that shows you how to add pictures.

@rany Done, I'll post some better photos soon
