Ipod has a blank white screen or "THE WHITE SCREEN OF DEATH"

Question

It's been like this for a while now and I don't know what to do besides to take it into the apple store since I think I have tried everything to help get it back to normal. Any suggestions?

Answer 1

I received a 4th Gen 20GB iPod (around 2 years old)from a friend and asked me whether I could fix it for him, which has been left untouched as a paper-weight for almost 2 months.
I tried to turn it on, and the screen was completed blank and the device looked dead. Before doing anything I prepared the following:-
1. A window based PC
2. A Mac computer
3. An USB iPod cable
4. A Firewire iPod cable
5. An iPod AC charger
As the iPod was previously formatted on a PC, therefore I tried to plug it with a PC via USB cable, it did not response and not able to get recognized by the PC. I ejected the iPod and connected with an AC charger, after a few minutes, I did a Reset for the iPod

The iPod showed an Apple sign, it stuck there for almost a minute, the screen then showed a battery with an exclamation mark sign, and after a minute, the iPod turned off itself. I was sure that the iPod carried very low battery, and could not be charged by connecting it with any computer (both Mac and PC).
I decided to let it have a charge with an AC charger for a bit longer, after 10 minute I did the Reset again, this time a sign of folder with exclamation mark showed up after the Apple sign, and again could not get recognized by a computer.
I changed my mind, and put the iPod into disk mode

Instead of connecting with a PC, I plug it with my Mac using a Firewire cable, it did not response, so I switched the cable to an USB, interestingly, the iPod got recognized and a window pop up indicating that the iPod needed to do a Restore. Therefore I clicked “Restore"
