I downloaded the Roamio user manual, but I didn't seen any screen shots:

and found this document from TiVo:

It had some images for the Diagnostics Screen. I copied the one for the errors, and edited it to make it a little lighter because the original was too dark:

Yes that is what the diagnostic screen looks like. I received a Wineguard HDA 200 amp in the mail today but I am assuming it wouldn't help anything although the amplification is supposed to be controllable via a nob or something. But, it may be "noiser" than the Winegard LNA 100. What do you guys think?
