Ahoj Tomaš. Umm yeah I didn't mean reballing, but yes, I wrote that. lol! No, I'm not ready for that yet, but it sounds like loads of fun, and I'm willing to try it sometime :) I meant like "reseating" or reheating the BGA from the top of the graphics chip (Nvidia). I imagine that precision heat gun we have with the soldering rework station in the lab would suffice? I don't want to use the oven in the kitchen because it is for food stuffs and also because the temperature, as I've read, can fluctuate radically. Perhaps we can hack together a technical oven someday with precision temperature control :)
I've read up a bit more, so now I must put the project on hold till we call Apple on Monday. Otherwise, we can perhaps meet there sometime and try it? If not on my GF's mac, I'd like to hack on some other failed Mac boards with the same problem.
BACKGROUND: This is the output from Apple's proprietary "Apple Service Diagnostic" software, which ITS.cz had in their diagnostic inventory: FAIL address: 0x0000100, expected: 0xc0000100, actual: 0x80000000c0000100 Frame Buffer Test - FAILED Error Code: 14
Nvidia on Apple MacBook Pro is notorious for this, and the state of Texas has launched a class action lawsuit against Apple/Nvidia. I'm writing this part to help other people that have the same problem how to get some compensation for this: http://support.apple.com/kb/TS2377 https://discussions.apple.com/thread/2777887?start=0&tstart=0 http://appleinsider.com/articles/10/09/29/07_08_macbook_pros_included_in_nvi... http://www.patentlyapple.com/patently-apple/2012/08/class-action-filed-again... http://www.nvidiadefect.com/nvidia-settlement-t874.html http://nvidiasettlement.com/
The other computers/laptops that were affected: Dell Inspiron, Dell Latitude, Dell Precision, Dell Vostro, Dell XPS and HP Compaq Presario and HP Pavilion and maybe more.

Hi Mario reballing is very hard work if you are not experienced to bga soldering you should leave this work to professional if you only want to try it with possible board damage we can try it together in Brmlab i have hot airgun with big power normal cooking oven can reach up to 210 Celsius ... we have one small in brmlab and nobody used it for cooking ( i hope ) :)
2013/7/17 Mario Lombardo mario@alienscience.com (cs) Zdar BRMlabčky! Chci používat technické trouby. Musím se "vařit" motherboard k mému MacBooku Pro podle této internetové adrese. Může někdo mi dovolte použít takovou troubu (univerzita?)? Myslím, že 160-190°C, je stačí.
Díky! /mario
Hi BRM! I'd like to use a technical oven. I must "cook" (reball) the graphics chip of my logic board in my MacBook Pro as per this link. Can anyone let me use such an oven, like at a university? A range of 160-190°C, should be enough.
Thanks! /mario
