Must change source selection - then go back to 'acquire' HTPC signal

[mitch77]

Hello,

When I turn on the TV I can never see the HTPC WIN 7 there.
I must take the TV remote, choose any other input source, then hit the source key again and choose the one the HTPC is on and it pops up.

If I leave it set - not playing a show it turns off as well.

It's a Samsung 55" in case that matters.

Any ideas? Thanks!
