I too faced this problem and I called the service engineer. He tried for almost 20 minutes and then finally told that there is a problem in LNB and he has done his level best etc. I am using 3 connections, so I am using a 3 output LNB. He told that it will cost 1500 + 150. I told him not required please try to tune with this same LNB, only for one channel I did not find it useful since I am getting Vijay HD. He just took 150 and left but i am getting only 60% signal strength now.. earlier I think it was above 75%
1500 for 3 output LNB ? Is that true
Since I am getting all channels including HD without any problem , there may be any problem with this LNB ?
