For a long time my brighthouse cable has worked fine but in the last several months ,I have had problems . Picture fading in and out, sound stoping for a few seconds , not able to get stations I have paid for and others not coming in. I get messages that the station is not available it this time .I have brought back cable boxes to the wildwood office three times in the last few months. I was told that they are sensitive . Has anyone else had these problems?
