From experience 0.023 amps would mean it is going straight into DFU mode. You could try and see if it is recognised with iTunes but most likely it will not.
There could be a number of reasons this is happening. You can start by measuring the voltage on the NAND and CPU power rails. If these rails are there you will then need to check most of the reset lines. If all these are good it would point to a communication problem between the NAND and CPU.
If it has suffered a drop it could have cracked one of the CPU coils, you might have to at least remove that shield so you can do a visual exam.
