Thanks a lot for your answer Duke. When I had a very bad time to find the other ones... I actually found 216-0811000 in Europe at a decent price...
I must confess that my experience on BGA rework is not amazing but I managed to get my hands on a ZM-R6200 at a very cheap price. I assume it will...
Hello,
Just reopening this thread as I'm looking where to source the GPU to replace a defective one. Duke, would you mind giving us any link for this ?
Thank you very much
Hello,
I have the following voltage behaviour when connecting the logic board through USB only :
- PP5V0_USB is fine
- VCC_MAIN jumps from 3.8V to 4.2V back and forth
-PP1V8_SDRAM : jumps between several variable values between 0.1V and 1.8V
-PP_BATT_VCC : jumps between several variable values...
Thanks for making it that clear Louis
I love corporates that go after European, North American or Australian citizens when the web is full of schematics / boardviews from other places. It's just like media antipiracy... Ridiculous... well I would actually say it is more ridiculous...
Well I managed to toast a chip : HPA02224RGRR-1-GP
Problem is I couldn't find this chip so I bought the same non working PCB and I'm now waiting for the delivery.

hI,
PU4201 : ok --> AD_JK=AD+=19.22V a,nd PWR_AD+_2=6.35V
PL4501 = 0V on both sides + continuity
PL4502 = 0V on both sides + continuity
I discovered some trouble with TPS51285ARUKR-GP. I only have 18.5V on one pin (my guess is DCBATOUT) and it's damned hot. The inductors are quite very hot as...
Hello,
I'm fixing this motherboard. When connected to power supply only or battery only, power led lights on and fans spin for half a second every 5/6 seconds, corresponding to a general voltage drop to 0V on the logic board.
I started to follow tracks ftrom DCIN but I feel this may take...
Well swapping chips is my usual option, I wanted to take the opportunity to learn more about iPhone logic boards... at the same time I'm not sure that learning on a 3GS would be the most usefull experience for the future...
Thanks for your fast answer
Hello,
