27" iMac (Late 2009)
3.06GHz Core 2 Duo
A1312 \ EMC 2309 \ MB952LL/A
PROBLEM:
STEPS TAKEN:
I know the obvious answer is to replace the logic board, but I'm trying to figure out where the failure is so I can possibly resolder and/or replace that component. The jack looks fine.
The only clue I have is that it hangs on the hardware test at the "Ethernet Controller (test #13) - PHY 10 Loopback Test" for about 2 minutes and then it passes.
Some expert advice would be most welcome.

STEPS TAKEN:
- Passes Apple Hardware Test with flying colors.
- Reset PRAM, SMC
- Tried different cables and modems.
- Fresh copy of Snow Leopard installed.
- Inspected Ethernet port for damage.
- Inspected logic board for blown capacitors, ect...
- Repeatedly hitting it with a hammer.
