HELP with Directv Multi-Satellite Dish (Monterrey, Mexico)

[enaplito]

Hi; I'currently relocated temporarly to Monterrey Mexico (about 150 miles south the Texas border)... I set up my Directv Dish Phase III succesfully for a few months receiving all 3 satellites (101, 110 and 119). When rains or simply cloudy I lose 110 and 119 partialy. Somebody told me that I need a bigger dish so I purchased a Channel Master 75cm dish with 3 separte LNB's (including SAT C kit). I tried to set it up, but I only get 101 perfectly (about 75 to 92 signal) but none of 110 or 119.

Manual says that for my location, the dish should be oriented AZ=202.4, EL=58.9 & Skew=110.4 This settings does pick 110 on about 50% signal put receiver post an ERROR: WRONG SATELLITE and 101 0%. If I align the dish to my former Phase III location, only 101 get the signal correct.

I also tried the SAT C LNB without the combiner to see if combiner is damaged and nothing. Also tried SAT B LNB alone without SAT C, and nothing.

Any Suggestions? I also have a singel LNB Dish that can I use for SAT C (110) only

Equipment:
Directv Samsung receiver SR-T160 HD
multiswitch ZINWELL 4X8
Channel Master dish with 3 separate LNB's

I hope somebody can help me.

Update....
The problem was a mixup conections between SAT A & SAT B LNB's. Everything was corrected and now all 3 SAT's work fine.
Thanks Anyway
