Member: 1421688 Status: Offline Thanks Meter: 6 | iPhone 3gs, what chip is damaged? This happened after a specific incident. The iPhone was plugged into an iMac's firewire port with a usb adaptor. Nothing seemed to happen, and afterwards an external hard drive was tried, and nothing seemed to happen. so everything was reconnecred via its normal USB ports but neither device was recognized any more. evidently the usb controller board for hard drive was fried and something of the iPhone's was too. So what needs to be replaced? my own research leads me to believe either the pmb6820 or the ltc4088-2. What do you all say on it? where should i proceed? |

Member: 1421688 Status: Offline Thanks Meter: 6 | Uploaded with ImageShack.us ok it looked like you wanted me to test the poles that i re-labeled with numbers. i wasnt sure if it was 2 fuses or the 2 legs of a fuse on the other side. anyway in ANY configuration all labeled poles showed continutity. the green fuse near vibrator also showed continuity. are the 2 smaller items near what i labeled related? because they had different readings which i won't list unless it matter |

Member: 1421688 Status: Offline Thanks Meter: 6 | i didn't remove the board for testing i just left it screwed into its housing. (just thought i should mention. don't see how would make a difference but just in case...) anyway, you really think its the battery? i only ask because the phone WILL turn on and function perfectly minus the fact it won't sync via cable or even be recognized. i would think syncing and battery would be unrelated, no? and secondly, if the phone is turned off and left on the wall charger it will gain SOME charge, very slowly. maybe 30% in 24 hours. but just to clarify the phone doesn't ever acknowledge that its receiving any current, meaning no beep, or batt icon change. although if turned off and put on the charger it will turn itself on. but thats it. |
