Turn ON/OFF problem
Hello All, having really strange issue with ON/OFF

Firstly when I try to turn on TV through home-kit it literally does nothing, meaning no logs are being generated even with deep debug on. After 1 minute or so tile in home-kit returns back to OFF.

Secondly, if I choose to turn on TV manually with remote it of course works but only for few minutes, then TV is turned off by the plugin, without me issuing command through home-kit. 

```
[4/26/2021, 8:58:26 AM] [homebridge-webos-tv] [LGTV] TV turned off!
[4/26/2021, 8:58:28 AM] [homebridge-webos-tv] [LGTV] TV turned off!
[4/26/2021, 8:58:43 AM] [homebridge-webos-tv] [LGTV] Disconnected from TV
[4/26/2021, 8:58:44 AM] [homebridge-webos-tv] [LGTV] Starting TV alive polling
```

Besides this ON/OFF problem everything works, I can change inputs, modify volume, control media, I can even turn TV OFF.
I'm at the end of the rope here, I have depleted all my ideas what could be wrong.

Here is my config:

            "devices": [
                {
                    "name": "LGTV",
                    "ip": "192.168.80.178",
                    "mac": "64:95:6c:33:19:d8",
                    "pollingInterval": 1,
                    "deepDebugLog": true,
                    "volumeLimit": 100,
                    "volumeControl": "buttons",
                    "channelControl": false,
                    "mediaControl": true,
                    "appButtons": [
                        {
                            "appId": "com.webos.app.livetv",
                            "name": "Cable"
                        },
                        {
                            "appId": "PS4",
                            "name": "com.webos.app.hdmi1"
                        },
                        {
                            "appId": "Shiled",
                            "name": "com.webos.app.hdmi2"
                        }
                    ]
                }
            ],
            "_bridge": {
                "username": "0E:E8:6E:1A:3A:9C",
                "port": 31951
            },
            "platform": "webostv"

Mobile TV in webos settings is turned ON.

Any help or ideas appreciated.

Oddly and luckily enough I found out this random turn OFF is not happening when my Nvidia Shield TV is turned ON.
So to workaround it at the moment I'm having my Shield always on and using it also to turn on the TV.
