MBP Crashes all the time. AHT Error 4SNS ICOC?
Hi everybody!
My MBP is crashing all the time while booting. Even when I use the MacOSX Install disk.. it`s crashing. I see the Apple Logo and the rotating ball for some seconds and then it`s crashing.
Then I started Mac Hardware Test. In the detailed Test my MBP crashes and when I start the standard Test while checking the logic board it stops and the message:
"Alert! Apple Hardware Test has detected an error.
4SNS/1/40000000: ICOC-48.730"
I took a pic of it if you want to see it.
I tried all shortcuts at startup. I tried with several hds and rams.
I didn`t find anybody who had the same problem with "ICOC-48.730" extension :(
Do anybody got an idea of what it could be?
Thanks in advance &
greetings
Marco
Update
OK.. dont need to answer anymore. This error indicates some faulty temp sensors and now it`s completely gone.
Topic closed :)
Is this a good question?

What was the source of the logic board and just how confident are you that it works?

thanks for reply.
I bought it at ebay from selling company (jkcomputerparts). I`m not really confident :) they told me it passed their quality tests. It`s under warranty so i`m able to change it, but i thought maybe anybody could say what this error means in detail, i had some hope to get it fixed.

I re-installed really everything veeeery carefully. Also checked heatpipe and thermal compound and all connections and cables, everything is fine.
After I was ready the macbook booted one time into MacOSX.. but I directly started again because I wanted to run it through AHT.
When the macbook was running for several seconds it`s gettin warm (normal temp, not hotter than usual) and then it won`t boot anymore.
Even hardware test won`t start.. direct shutdown.
Then I give it some minutes to cool down and tried again.. Then I came into AHT and run the test. First time it shut down, second time it worked with the same error as result.. just a different variable at the end ICOC-52.757 instead of ICOC-48.730
