No power, warm upper circuit board, not recognized in itunes
I replaced an iPod touch 4 LCD assembly for somebody and when I went to turn it on for the first time, it would not boot up. I didn't even get a black/white screen. I changed out the headphone jack (red indicator), swapped the battery, changed the power/volume ribbon, changed out the home button flex. Everything looks good, but no power.
Plug into computer to attempt a restore. The computer (Windows 7) recognizes that I plugged something in but doesn't know what (unknown device). I held the power and home buttons to force hard reboot, drivers not successfully installed. Windows is kicking out code 43-Windows has stopped this device because it has reported problems. One time I also got code 29-This device is disabled because the firmware of the device did not give it the required resources. I ran the diagnostics in iTunes and it came up with no iPod, iPhone, iPad plugged in.
The iPod is VERY warm in the region where the flex cable is soldered to whenever plugged it/attempted to be turned on (even after I De-soldered the flex and plugged into computer). I spoke to somebody at a repair shop and they said that area of the circuit board should not get warm.
I don't know what else could be wrong with it, but need to figure this out asap so I don't have to buy them a new iPod. Any help would be greatly appreciated! Let me know if any additional information would be helpful.
Windows 7 Ultimate 64bit PC (up to date-2x different PCs)
iPod touch 4th 8GB (1367)
iTunes version 11.0.1 (current)
Is this a good question?
