iPod touch Repairing an iPod Touch 2G

[yellowplum]

I just picked up an audio jack to repair an iPod touch and also replace the damaged digitiser. My issues began after I replaced the jack, the screen was functioning previously up until I soldered the replacement jack onto the board.

Once this had occurred the screen now just remains white. I have googled the typical responses but it seems this also occurs when you don't attempt a repair.

I don't have a problem ordering a new LCD screen to replace if I have managed to damage something (which I was very careful not to) although I also read that you can damage the logic board because of soldering.

Any ideas what it could be and how to determine what I have actually done?

Sounds like the device either needs a hard reboot (hold the power and home button for 10+ seconds until device reboots), needs a new LCD, or something has shorted on the Logic Board.

A common issue I have found if the LCD is damaged, you will either clearly see damage to it, or the LCD will become inverted. Are you experiencing any of those?

I have been trying the hard reboot a few times today to no avail. I did also plug it to my MBP and reset it (while this worked it didn't display anything on the screen). It seems I can use the iPod but nothing displays on the screen. I even managed a picture taking noise.

I think I might have an idea as to how/what I did to cause this to happen. When I was repairing the iPod I was unable to actually turn the device off because of the damage to the digitiser. Hence I just took it apart with power still going to the LCD. This may have caused the problem?

I have no issue replacing the LCD, I just hope that is all the problem is and nothing more on the logic board.

Any other suggestions?
