It's interesting...
I have good PIP window. I can feed a line in (S-video,etc)audio/video
signal OK. Just the main TV is blue with no sound on "tuner".
If I change channels with the remote (directly enter numbers) I hear a
split second of audio for that station as it changes, but no picture.
Like it's being muted.
I have most all the IC's on this A/V board ordered from Tritronics. Most
not expensive at all. Will see in a few days.
