that's really nice of you, INsignia, but see my post - I already called you! and they did all the "troubleshooting" (everything I'd already done after reading the manual!) and was told there was nothing to be done and I'd have to check with TV manufacturer about apps or call a technician - right.
Sorry, there was a problem. Please try again later.
