@umlee168: These sorts of codes, usually when a reboot doesn't complete, are an indication of a signal issue, either in your home or in your neighbourhood. Check out the following post on the topic - check the signal yourself if you can get it to boot and/or call Rogers and have them check the signal in your home (at the specific box) and in your neighbourhood. They can do this remotely.
My 90 year old mother lives in a retirement community. They recently “upgraded” to these refurbished 8600 HD s. She has a 6 year old tv. The NextBox is not working. They are telling her that she needs a new tv because her tv is slow. It is not her tv that is slow, it is the nextbox. How can Rogers help her ? How can I help her? She needs a tv more than ever with the current covid restrictions.
The 8600 should work with any TV. Here are my comments/questions:
1. What connection is she using between the Box and TV? (HDMI, Component? Composite?)
2. What is the exact make/model of the TV?
3. Is the TV on the correct input?
4. Try a composite connection (yellow cable) as a test. Make sure to switch to that input.
5. If that works, set the video output under "settings" to whatever the TV will accept. Most HDTVs will accept 1080i. Perhaps the box is currently set to something that the TV will not accept, like 1080P.
6. I'm assuming that the box boots up and shows the time.
7. The people who handle retirement community issue at Rogers is a different group and you'll need to contact the retirement community manager to get the contact information if the above doesn't work.
