Mysterious Problem!!!!!!!!!!!!!
I bought from ebay this new Ku DUAL LNBF .4 noise figure made by LAVA to replaced my old working International dual LNb .6 noise figure. I am using DVR 522 two tuner with no switch getting signal from SAT 121 only.
I installed and i run the check swich on my receiver, it will stop after checking the first swich and I get the message that sat 121 o.k with device : DP FEED and SWICH: DP FEED. when i checked the signal strenth it was only signal on transponder 2,4,6,8,10 (only) from the 32 Transponder.
what should I do?
