As for the toilet, sounds like maybe a bad valve. I would loosen the line coming to the toilet and verify I had water pressure to the valve. I may have been unhooked and capped due a freeze sometime. Once I was sure of water pressure, I would look at the valve on the toilet for the problem. Might be able to find a diagram on the internet if you search.
As for the refer, quit opening the door so much. Will stay colder too. This is not a home refer, so plan when you are going to open and close the refer. Mine has a drain to collect the water and release it outside.
As for Television, you eithet have to have a digital t.v, pr a converter box. No analog stations left. Use a known working t.v from the house and try it.
Hope this helps a little. Maybe some others will have some ideas.
