We were out and the kids were home alone. We don't know which satellite the dish was pointed to. Probably G1. Lightning struck. There was a surge that took out a VCR, a TV, a BATTERY-POWERD radio alarm clock, and 2 phone answering machines. The 4DTV went into recycly with WM UP. When it came back the kids say the picture was OK, but I can't verify. Overnight at 2:00AM it tried to do its nightly thing and go to G1. However, when I turned it on 2 days later it couldn't find any channel. I asked the 4DTV to go to W6 for the NASA channels on MPEG. It appeared as though everyting was OK because the check mark moved its way throught the satellite buttons until it came to W6. But no reception. I went to "program satellites" to find the dish position number was not what it should be. I ended going to "set limits to see if something was messed up there. Here's what happened: This dish was at 3983 (W6 is supposed to be 3925). East limit was 3780 (where I originally set it). When I hi-lited "east limit" and tried to move the dish east limit became set at 3983. I hi-lited "west limit" and when I tried to move the dish west limit became set at 3983. When I hold down on the arrow that asks the dish to move, after about 3 seconds I get "dish at physical limit". I reset and try doing it one tick at a time. The dish actually moves but the position number never changes on the 4DTV. Even though it is a linear west setup, nudging the positioner one click at a time I can move the dish from nearly the west horizon to pretty close to east horizon. (I never KNEW it could go that far east!) But the position numbers on the 4DTV don't change. I did a master reset (oh joy!) and when I go to set limits all 3 numbers were at 5000: dish position, east limit, west limit. I try to move the dish and the position numbers can change a bit to the east (to 4978) but even though the dish can keep moving nearly to the east horizon, the numbers don't change. Same as to the west: even though I can move the dish to the west horizon the numbers don't change. Dish position 5000, east limit 5000, west limit 5000. When I try to program a satellite, no matter which satellite it thinks it should be at 4978 (the new east limit.) So, what's broken here, the actuator or the 4DTV? As I said, one click at a time and the dish will move. But try to move it all at once and it can't go beyond the limits and I can't set the limits because the numbers don't change as the dish moves. How dio I determine where the problem is?
