Mysterious Problem!!!!!!!!!!!!!

[ebehalifax]

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?

My first thought is that it's NOT a compatible LNB.

It's voltage-switched, but being detected as DishPro - that's NOT going to work.

Also, 121 is 11.7-12.1GHz, which per your specs is "high-band" which it outputs starting at 1100MHz, but 'standard' LNBs start at 950MHz.

Finally, it looks like it needs a 22KHz tone to run as 'high-band', and E* boxes don't use that.

The only thing you might try is disconnecting it, running a Check Switch to reset the receiver to Legacy mode, and then trying again, but I really have no hope.
