Got a 27 inch GE model #27GT616. DishTV is our provider..it was plugged straight into the tv and was working fine. We unplugged the cable to try to use a splitter so we could attach a DVD player to the tv. We never got the DVD player to work, so we plugged the DishTV cable back into the GE tv...now all we get is snow and Dish has no idea what to do to fix it. We have tried changing channels and nothing is working!
