Is there a way to test the motherboard is working?

文本:

I've got a faulty iPhone 3G which doesn't turn on or anything, has cracked up screen. Before buying a new LCD I want to be sure the motherboard isn't broken, is there a way to know? The only thing I've had is a noise from the iphone when connecting it to a PC.

I've also powered it from a 4.1v LiPo cell because the battery inside wasn't working, hoping that's ok? (a bit confusing as there are 4 contacts)

Thank you very much
