Lost Sat B

04-09-2005, 08:29 PM
I need some help. I have lost the signal from Sat B (119) and about half of my HD stations (including ESPN-HD). The receiver has worked fine for about two weeks ( I purchased a used Zenith SAT-520) but today, Sat B shows zero signal strength, nada, Sat A is about 95 and Sat C is about 60. The only thing that may have changed is that my dish points towards some neighbors crepe myrtles that literally have bloomed in the past two days, so maybe the leaves are effecting the signal, however before I replace dish, I was wondering if anyone has had this problem, or similar, before.

When I set up initially two weeks ago:

Sat A - 95
Sat B - 70
Sat C 60

Sat A - 95
Sat B - 0
Sat C 66

Have had heavy rains the past week
Have had a hail storm in the past week
Inspected cable no visible damage
Verified connections on cable tight

Cracked/wet LNB?
Obstructions in front of dish?
Receiver problems?
Tilt (Sat B is sensitive to that, I was told)?

Any thoughts appreciated.

Were there some high winds with those rains and hail? I don't know how your dish is mounted, but they have nasty habit of shifting in high winds if the base is just screwed into roof decking. It could be the tree also.

Dish is mounted to side of house (brick) - does not apprear to have moved, based on "tic" marks I made two weeks ago still being aligned.

Check the obvious things first. I would expose the coax connections at the LNB and give the connectors a tug to see if they're crimped correctly. It's possible that lightning took out an LNB (less likely).

Replaced LNB - no change.

When I replaced my 2 LNB dish with a 3 LNB dish a couple months ago I had trouble getting SAT B also. I got A and C just fine but B must be lower in the sky than A and C. I had to move my dish straight up about 3 foot. Now it works fine. I think those crepe myrtles are blocking SAT B.

The 119 sat is the lowest bird in the sky for most of the US.

Thanks for all the info - I will be relocating my dish this week as that no amount of adjustment seems to help. FYI - The signal from Sat B worked fine for about two weeks when first installed (whe the shrubs had no leaves) but as soon as they came out - no Sat B no more. One suggesstion (from DTV tech support) was to try to adjust the tilt. Anybody think that would help?

Thnaks again.
