Update: Just figured out that the problem is that my POS HT900 only outputs video when playing a DVD which i guess makes sense although seeing as the video sensor doesnt work and as mentioned above it also has neither an switched ac outlet or 12v trigger so i can't use a voltage sensor i might be SOL. It does have FM & AM outlets for each antenna. Dont suppose there is any chance i could use one of those with a voltage sensor :) ?

If not it seems that the only way to figure if this HT900 is off/on would be with one of these

although it cost almost as much as the whole HTiB. Anything cheaper out there?

thx
