I've been very unlucky to have dropped my phone, and Nokia won't help me at all fixing it.
Two SMD components (I believe it's a resistor and a capacitor) have fallen of what i believe is the internal power Circuit.
The phone is now completely unresponsive.

I would like to try and fix this myself. Can anybody help me figure out what excact components are missing?
Here are a few pictures of the damaged area

It would be a shame to throw out a phone, which can be fixed with components worth 1p.

Thank you

You?re absolutely right. These are very small components and can easily be replaced. However, the values of these SMD components is very crucial towards the phone?s actual revival and for that, a closer look is required. It is evident that this is a small power circuit. If you could read the name of the IC, we can then try to reverse engineer the circuit and by comparing the circuit with the application note of the IC, we might eventually find the type and value of these components.
