Only one channel on my jwin dtv4622 is going to black and white after a few minutes. If I changed the channel then go back it was fine for a few minutes. Now it will only be in black and white. I have checked the other tv's in the house and the one channel is in color but not this one tv. Why is this one channel in black and white while the rest of the 75 channels are in color?
Not the tv,it the brocasting incoming signal cable have a slice matalic contacting to that procise prequencies problems for that channel.Take another tv used it,with that incoming signal for that channel for a few days.See,if have a same problems have happen to another tv?Yes,than call the Cables,Dishes or Telicoms compannies,change that section of the incoming of broscasting signal cable line.Not,than take a piece of sand paper about 1000 grits,rub the input metal pin a few times,to have it better contact.
