General Clock and Stereo not working after swapping Stereo

MG ZS MK1:



Hi, My clock and Stereo will not turn/no power !



All i did was:

Took out my stereo

Put my mates in to test it (bought second hand), it worked

Put mine back in





Now there's no clock on and my stereo no longer turns on!



Both our Stereos are sony, i swapped and exchanged about 4 different Stereo's recently and all was fine.



I've checked ALL the fuses under the dash and none seem to be broken!.. 23 is for the clock and Audio.. but that isn't damaged.



what to do??
