Hello, i just took apart my x-box put in a new green led fan,also put in a 160 gig seagate hdd and set it to master. I went down to radio shack and bought a 15 watt soldering iron and 0.032 solder. I soldered amd installed an xecuter 3ce chip set....well i just put it all together fired it up and got a code 16 and the xecuter switch does not light up at all? im new to soldering and was wondering if that could be it or the new hdd would prevent anything from happening as well? should i put in the old hdd? and resolder?any help is highly appriciated? p.s The fan works
