Hi, I have a “single view” DSD720i DSTV decoder and a single LNB. My reception was fine until about the beginning of December 2005. Since then I get a “Searching for Signal at ---MHz” error on some of the channels and only during the day. In the evenings my reception is still fine.
As you probably know, the DSTV channels can be divided into two reception blocks (one vertically polarized and one horizontally polarized, I think) and if you have a dual view decoder with a single LNB, you can only watch two channels from the same block at the same time. The channels that I usually watch (Mnet, Movie channels, Sport channels, Prime, Kyknet, etc.) are all in the same (vertically polarized) block and this is the block that I do not have any reception on during the day time.
My signal strength and signal quality for all channels were all at about 80%. Now, during the day from about 9:00 till about 16:00, the signal quality on the vertically polarized block drops to about 10% and I am not able to watch any of these channels. The signal strength and quality for the horizontally polarized block however stays at about 80% and those channels I can watch during this period. Then at about 16:00 in the afternoon the signal quality of both blocks is up at about 80% again and all channels can be watched again until the next day.
Has anybody experienced or heard of a similar problem and do you know what I can do to fix this? I have phoned Multichoice and they say that there is nothing wrong with the signal. There is also no problem with the decoder. I have tested it, a friend’s decoder, that is working fine at his home, is giving exactly the same problem at my house connected to my dish.
Thanks.
Kobus.
