I need help! After recently spilling beer on my iPod touch (D'oh!), it's backlight stopped working. Everything else works fine, it's just the backlight. The iPod is out of warranty and would cost me an arm and a leg to replace. I tried replacing the LCD screen thinking that would solve the problem but to no avail. What is it thats causing this problem? And how can i fix it? Any answers would be kindly appreciated. Many thanks.
