Hi, right got a water damaged iPhone 3G 16gb White yesterday that was showing no sign life, so popped the motherboard out of it and put it into my White 3G (with everything of my fully working 3G) and plugged it into computer, straight away it recognized in iTunes and i could restore the phone, sync ect.... But the screen just stays blank? At first it did go just white and then go back to black or would stay on white for a bit. Any ideas on how to fix this problem? The screen off the water damaged one is also fine because i tried that on my fully working 3G.

I can't work it out? All the connections for the screen are on how they should be.

Anyone could help i would be really great full.

Thanks.
