the white screen simply means that your iPod has a backlight. Since it has no video and the beeping, sounds like an issue with your logicboard. You will have to disassemble it using this guide [guide|423] and take a look at the board. Check for damaged looking components. There are no schematics available and they are a PITA to work on, so this will not be an easy repair.
