Cable TV has been out for a day. Any other suggestions?

TV is out. Cox support tells me that they are not able to get a signal out to my residence and can’t have a service person come to my house for 3 days. Is there anything else that I can try to fix it?  I have reset and unplugged everything several times, and that doesn’t work.  I think the problem may be with the junction box that sits in one of my neighbors’ back yards.
