Belgand,

I have the same issue with the 970 (basically 1070 minus the amps). I get the white flashing and I also have a 6" vertical band on the left side of my 92" screen that looks like a thin grayscale bar has been laid on top of it. I have talked to Scott and he told me to try a reset, although he thought that may not work as it sounds like a hardware issue. I am going to try later tonight.
