Please DO!

I've been battling the same issue on our demo system and 1 clients' home.

I noticed that when the screen dimmed to the "idle" mode... the lines came on. SO I put the thing in FULL ON mode and it cleared up to 90%. (basically same thing you did...).. I'll have to try an isolator for the other 10%

My guess is they should be able to fix this issue at the hardware level somehow...now that we have narrowed the search down a bit.
