My tv was working fine last night. I rolled on top of the remote and the picture is now fuzzy and no sound. I thought all i had to do was put it back on the right channel but its not working. I disconnected the tv, set top box for a few minutes but nothing. So I went on live chat last night and they are completely useless. Is it a real person you talk to or is it a computer? When they said for me to do whatever I did it and then I said it did not fix the problem. Instead of suggesting something else, they would just repeat the steps again and again until I ended the conversation. My husband thinks we need a new tv because it is old but I dont believe thats the case. Any ideas?
