First of all, I have a VIP622 connected to two dishes, a dish 500 for the 129 satellite and a dish 1000 for the 110 and 119 satellites, this was a new install. The tech connected these satellites thru my OTA antenna coming into my house. This worked perfect for about 5 months, then bang no signal coming into the receiver. I called Dish and they sent out another tech from the same company that did the initial installation. First of all, he said I have never seen an install like this before, talking about the two dishes, that sounded odd to me but to make a long story short, he replaced the 129 LNB, as he thought this might be the problem and after about 2 hours, we finally had a signal coming into the receiver...problem solved, we thought. Worked for a couple of days, same problem, this time, he said it must be the receiver and he replaced it with a new one. Again worked for about another 3 days and we still have the same problem.. He came back again, this time at night and of course, he couldn't trace anything at night but said he would be back the next day, called and said he was tied up and couldn't come but would try and get by today.. A no show so far today and we are still without a signal coming to the receiver. I asked the first tech that did the initial install if he had ever installed a 622 before and he said no, this was his first. I asked the second tech that has been coming this time and he said he had never installed a 622 either only been working with this company for only 3 months. just my luck, after the second time he came, he was trying but he just doesn't know what to do. If the receiver was mine and not a lease, I would go over everything but I don't want to void my warranty. I think it has to do with the switches or the LNB's and the way they have it connected, we are just not getting a signal, it comes and goes. Sometime when you turn the receiver from OTA to Satellite, we get no signal and the 015 message comes up searching for satellite. I am paying Dish $100 mo and can't get programming half the time.... What do you guys think is wrong, any help I can give the tech if he finally come would be appreciated, sorry for the long post but I really need some help here. Thanks,
