The primary things to check if you Raspberry Pi does not work are the power supply and the SD card.

The power test points TP1/TP2 should be at or above 4.75V and below 5.25V. Some cell phone adapters cannot keep up the voltage when under a load. This is the weakness of using a cell phone adapter to power the Raspberry Pi.

The most common problems with the SD card are improperly “burned”. If you are not sure whether you have properly setup your SD card then I recommend you try NOOBS (New Out Of Box System). You do not burn NOOBS you copy it onto a SD card.
