at least i'm trying

be careful, i like to use digital multimeters, infrared thermometers, hot air soldering stations and i need a lot of alcohol (but only isopropyl with more than 90%)

jejejoey - almost correct! they switched to lead-free - thats right (to anybody who cares ->google "RoHS" for more information about that topic). the melting temperature is exactly the other way. leaded solder melts earlier then lead-free solder. the lead-free solder is "harder" - and that's why it breaks. you can read more about it on wikipedia -> http://en.wikipedia.org/wiki/Restriction...

you have to replace the lcd - it should not be that expensive ;-)

this porblem can be fixed, but not that easy. there are many companies that offer the gpu repair for the mackbook pro - the price in germany is around 149€ maybe you should search ebay or something like that

the ethernet card is only a chip on the mainboard - it's not possible to replace it with a plug and play solution Guide Step 14 in particular

i corrected the category for the mbp i think that it might not be that expensive here are the ifixit prices... aiport card 79,95 battery 109,95 keyboard 99,95 superdrive 149,95 but i'm pretty sure that you have many other options for those parts ebay.com airport card around 11 battery 26 (but this might be a pretty crappy battery) keyboard 30 suerdrive 40 those are all "buy it now" prices - auction prices can be lower.....

Réponse à : « part divice effect Soldering » 26 déc. 2011
nothing to solder there - it's an emi shield - the phone would even work without that shield (but that would not the best idea)
Réponse à : « Headphone jack doesn't work and volume buttons dont function? » 26 déc. 2011
open the phone and check the connector from the headphone jack assembly - sometimes it's not properly seated. but it could be damaged too i would check the resistors near the connector on the logicboard - had a few phones with broken resistors! (would that check before you order a new assembly) replacing the plastic case is easy if you already stripped almost everything - but as i mentioned earlier - try to get it fixed first and then order parts - they are too expensive - especially when the rest wont work....
Réponse à : « Touchscreen wont respond when I try to unlock phone...? » 26 déc. 2011
hi matt, i would use the motherboard guide (click) and check all the connections inside the phone - most likely is a connection poped out of the socket - but it's also possible that the soldering of a chip got damaged - but as i said - check the connections first - good luck
