I am going to assume you are jail broken. You get the white icons when your icon cache becomes corrupted. And, the only thing you can do is to respring the iPad again.
Try installing a free tweak from Cydia called "Respring." Between that one or Springtomize 2, either works the best to fully clean the cache so your icons appear normal.

P.S. And, since you talk about a jail broken iPad, I've taken the liberty of moving your post over to the Hacking section. Thanks for your understanding.
