I've recently obtained another v1.6 Xbox, but it conked out on me, even though it was working fine hours before. I wanna test the PSU but don't know how. Can we test IC using a multimeter | Electronics … Multimeter can only be used to test the IC dc supply voltage and to use the ohm range to find out if the IC is shorted to ground or not. Generally using an oscilloscope to test an IC is much more accurate because one could see the input and the output signal assuming if the IC did not develop any short circuit and has the right DC SUPPLY input (VCC).
