My non-X1 set top box will not longer show HD channels

I have two RNG150N boxes. I have an HD account and usually they both show all available content. One I haven't used for a few months so I had turned off (24 watts when its off btw). When I turned it on yesterday to use this week it would only show SD channels. No wiring or equipment changes have occurred. I tried to reset the box and Xfinity could not contact it. I gave it overnight to try and sort itself out and no joy today. Screen says "ONLY AVAILABLE WITH HD SERVICE". The other RNG150N is working fine. Worst case I could swap the boxes but that is pretty low rent. Did leaving it turned off zombie the box? Thanks.

user_ywmsu6 Hello and thank you for reaching out via our Xfinty Community forums. 

I understand you're seeing "ONLY AVAILABLE WITH HD SERVICE" on one of your RNG150N boxes, while the other is working fine, especially after it was off for a while. That's certainly frustrating when you expect both to show all your HD content.

It's hard to say definitively what caused this – sometimes a box can lose its full provisioning or encounter an issue after being powered off for an extended period, even without physical changes.

 

We have a couple of good options to get you back to enjoying all your HD channels:

  1. Swap the Box Yourself: The quickest way to resolve this is to visit your local Xfinity Service Center. They can swap out the problematic RNG150N box for a new one on the spot. This way, you're in control of the timing. You can find your nearest location and their hours by visiting xfinity.com/stores.

  2. Order a Replacement: If you'd prefer, we can also arrange to have a replacement box shipped directly to your home. This might take a few business days to arrive, but it saves you a trip.

Which option would work best for you?

@XfinityChristy​ Thanx. If I had one shipped I would still have to go to the xfinity store to take the old one back so it is no saving of hassle for me. Otherwise I would cheerfully pay the $15. :-) I'll just physically swap the two boxes until I go that way again and swap the bad one at the store.

Btw, I had a tech out years ago to replace one of these and he said that xfinity had not procured any new set top boxes of this type for some time and were just refurb/recycling them. In fact, he unwrapped three (3) of them on his truck and none of them worked. Fortunately the 4th one worked. :-)

Thanks again.

user_ywmsu6 I completely understand your reasoning for wanting to swap them yourself rather than wait for a shipment – saving a trip is definitely key! I'm glad you have a workaround by physically swapping the boxes until your next store visit. Thanks for sharing that insight about the RNG150N boxes. It's definitely helpful context, and I appreciate you bringing it to our attention. We always aim for a smooth experience from the first try, so I'm sorry to hear that wasn't the case for you.  
 
I hope the swap helps you get back to enjoying all your HD content on both TVs without any further hiccups. If you have any other questions or need anything else in the future, please don't hesitate to create a new post here on the Xfinity Community Forums. We're always here to help!

@XfinityChristy​ Hm, not so fast. If I ordered a replacement will that come with a prepaid label  UPS/Fedex type thing? The "internet" suggests that may be

that case. That would be easy. My Xfinity store is a long way away but there are a ton of shipping drop off spots around here. Is the "internet" right? Thanks.

After 40 years of using comcast I am still learning. :-)

user_ywmsu6 When swapping Xfinity equipment, you should get a return label with the new equipment. That way you can box up the old equipment, and call for a pickup.
