not sure I understand, by identify do you mean determine where it's
coming from? By any chance is it vertical blue bars that show up mostly
on the bottom half of the screen, mostly when the tm is on say, 1/2
or more? Reason I ask that is I'm running a similar set up, and that's
what I have. Haven't had time to try and fix mine yet.
I have found out my problem shows up with the 83 wide beam,
if I turn it off or cut the sensitivity down to nothing it goes away.
