How to shut down the device not restart

Text:

hi,

I replaced broken panel with a new part. But the new part was a faulty part! Lcd shows nothing and of course touch panel does not work. I want to replace it with another new part but here is the problem. I don't know how to shutdown (not restart) before I open the back case. Could anyone please tell me precisely how to shutdown iphone by combo pressing sleep or home button in a correct manner.

Thank you in advance

Device:

iPhone 4
