Apple logo and then white screen on start up
I've reassembled my 3g after attempting to fix my power button (it was very unresponsive).
Now, when the phone is turned on, I get the start up screen with apple logo and black background but then my screen goes a yellowy colour and then turns white.
I've restarted the phone using the Home + Power button technique, and attempted to restore the iPhone (I've also tried different versions), the iPhone displays the iTunes logo and sync cable but as soon as the update process begins the screen goes white again followed by error 1603.
I thought that it may be connector 1 causing the issue, but surely it wouldn't show the black background, and apple logo if that was the problem?
It appears to charge upon USB insertion (without display) but isn't detected by iTunes, ONLY in recovery mode.
Any help is greatly appreciated.
