I am seeing green sparkles on the screen. Easier to see in darker backgrounds. It's not the tv or my receiver admit doesn't do it on the same input with a Blu Ray player attached. I haven't seen this issue in the thread. Also, frequently when I change channels I get a gray screen the looks like a jigsaw picture of the screen. It's hard to describe. I thought it might be because the 34 was just installed and things needed to load up. But I have not seen this on any other D* receiver and I have had a bunch of them. Thanks for any thoughts.
