Answer to "White screen after changing rear panel"This is what I've learned: -some people can get the screen back by restoring firmware or performing a hard reset. It's worked for me but in just a few cases. If it works for you, then consider yourself lucky. Done. -what is usually the case (and frustratingly so since you'll try EVERYTHING like I did) is that the battery has to completely discharge. Yep, put it away for a few days and then come back to it later. Avoid powering the unit on until everything is properly seated. If you have a white screen, it does NOT mean the screen is defective; there has been hardware changes and the unit has to be drained of all possible charge to have a fresh boot - much like any computer.
