I know this is a very very old post. 
	I also have the QT428 and I am having issues. 
	I really do not want to throw this thing away, I would rather fix it. 
	Mine turns on but stays at the “system initialing” screen. 
	I can feel the hard drive start to spin when I turn the unit on, but it remains at the “system initialing” screen. 
	I have tried unplugging the hard drive as others have suggested and when I poser on it still stays at the “system initialing” screen. It will not go any further.
 
	I am open to any advice. 
	Is the unit fixable? 
	Should I just throw it away?
