smartxxv3 on v1.6box; manufactured on 2004-09-09, hence last 5 digets of serial: 43705
Wire rebuild of LPC, no apparent dry joints, two previous installs on this version plus 4 on v1.0 to V1.4, all went well. Am reasonable at soldering.
Put power lead into socket according to manufacture,s manual (socket on upper left edge, closest to IDE socket on mobo.
Firstly chip would not light up or pull down do (L frame), got M$ dash first then error message no. 07
I then pulled the box appart and Earthed L frame direct, once again no activity from chip and xbox kept rebooting.
swapped another chip and dvd power leads to power the chip, still the same result.
disconnected the L frame from earth and Xbox dash rebooted followed by error 07.
RAM is Samsung --no sign of Hynex RAM as have seen where V1.6B has issues with Smartxx o/s if not the latest. Both chips were bought only three months ago, so O/S should be up to date.
Both smartxx chips are just dead, will not pull DO to earth and no LEDs light up.
Am at a loss as what to do as all the soldering looks good and there is no fragging until error 07 comes up
