On my WS-65517, I was going to watch a DVD and pushed the device button on the remote but it did not work. So tried the front panel button but it does not work either. But somehow it did change it to ant1 and now I do not have a picture just static. I tried doing the manual reset, unplugging the tv and nothing works. I have dish network, a dvd player and surround system hooked up. I can hear the channel the satellite is on thru the surround sound but really need the picture to go along with it. Any suggestions? Please help as my husband is really angry with me for messing up his TV!!
