My TV died

A few minutes before, I want to make a little knitting rest on the couch and watching TV. So I made the TV on, but nothing. All other stuff went on, but not the TV. Grrrh, who one had killed my TV? I hope that this is something you can be fixed, but at the other side, it is a older TV, so a new one would be nice too. :-) I will wait until my husband come home and we will see what to do. Luckily we have also a TV at the kitchen and so I can watch there, but it is not so much comfort like at the couch.
