So first, you'd need to download and install special software to the TV to
get the LEDs to show what you want?

The TV downloads updates regularly. You'd just have to fool it into
loading some hacked update instead of the genuine thing. That could
be done by poisening your DNS entries or intercepting the update
traffic. With good security, these things would be difficult (but
not impossible). However, such appliances are well known for appalling
security. Another way would be to exploit a buffer overrun or similar
in some the the media decoding software, and providing a hacked film
or whatever that causes execution of embedded code via this mechanism.
