Intermittent RDK error codes

The error is on live tv, when the live tv is working.  Sometimes, the box stays stuck on the welcome screen instead.  When I check the site for outages, it doesn't show any outage in my area.  Is there a better way to check for outages?  What happened to the live chat?

Hmm, that is certainly strange @user_32f748! We are here to help, and want to ensure that all the steps taken are available for the resolution. 

Can you share with us any troubleshooting steps you have completed? Did you recently swap the box? 

The issues started around two months ago.  So far, I have:
-at the suggestion of the support team, I swapped the box, twice
-refreshed the signal over the phone many times
-a technician arrived and ran a new line to the house last month
-unplugging the box rarely helps

I don't know what else I can check or what options there are.  There is another technician scheduled in a few days, but I don't know if they can do anything else, since they just ran a new line.

Let's do a little extra digging; but also make contact, so we can check in with you after your tech visit as well.

I tried sending a direct message yesterday with those same steps, but I did not see any response.  I will try again now.  Also, can you confirm if live chat still exists (and paste a link)?  I only see the assistant/bot now.
