Check how much current the device takes from the battery. If it's above 300/400mA, you're pretty sure that there's a shorted circuit due to some broken components. If it takes below 100mA you're pretty sure that the device is in "sleep mode", i.e. it could start working but it doesn't (at this point, check the power on button). With this dicotomy you should half the range of problems
