Answered Hide HTML Code if TV is empty

<!-- since not all devices will have 7 features, only display the 7th feature if it is there. This avoids taking up blank space at the end of the data --> 
[[*features-text-07:notempty=`
<div class="features-caption-2013">[[*features-caption-07]]</div>
<div class="features-picture-2013"><img src="[[*features-picture-07]]" width="240" height="190" alt="feature for 2013 Yamaha Sport Boat"></div>
<div class="features-text-2013">[[*features-text-07]]</div>
`]]

Not sure if the above will work for your situation.

I think that the best way to debug this is trying to output the tv in th page.
One time when it's checked, and a second when it's not.
Then you can write the right condition. (It should be 0 and 1).

Are you outputting up to 7 features?

While this should work somehow, but seems it doesn't in your situation,
may be you could use one MIGX-TV for all features, and all would be good.

If I understand you correctly, I suggest you put your output in a chunk.
Then the checkbox will be used just to determine if the the chunk should be shown on the page.

what are the input-options of this checkbox?
