MaxListenersExceeded warning
Any idea what's happened here? Can't turn the tv on via Home or Remote. I am currently quite unpopular at home!

```
(node:567) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 tvTurnedOn listeners added to [LgTvController]. Use emitter.setMaxListeners() to increase limit
(Use `node --trace-warnings ...` to show where the warning was created)
```
