HD DVR receiver loses channels, Other receiver works

[tiny]

Recently I have been having problems with my HD DR receiver. At first we lost the local channels and did reset. The channels came back. Then we received the 771 message and lost some cable channels. I called directv and they fixed the problem. Next day it was out. Called directv and fixed it. Then after repeating this multiple times they say I need to realign the satellite. However, my other receiver (SD) shows signals of 95-100 and we have all the channels and have not had any issues with it. I am thinking the receiver itself is going out or that the b-band converters may be bad or another connection problem. Generally I can reset the receiver and we get all our channels back, but that gets very annoying on a daily basis. I appreciate any help!

Thoughts?

The HD and SD signals are from different sats so you can't go by what your SD receiver is doing as a test for HD channels. What signals are you getting on the 103 & 99 on the HD receiver?

Receivers rarely are the cause of SFSS but it's a possibility. Most likely causes are alignment, line of sight, or bad connection.

What dish? What LNB?
Have you tried using different cable connections to the dish.
List all signal strengths on all sats and transponders.

99c: 74 0 72 0 0 0 52 0
49 0 60 0 62 0 62 0
N/A ...
99s: 0 0 0 0 0 0 n/a n/a...

103s: same as 99 s - mostly 0's or N/A
103ca: first 8 are n/a, 9-24 are 0, 25-32 n/a
103cb same as 103 ca

5 LNB

(Azimuth 153, Elev 42, Tilt 101)

Any other info needed? As of today it is all working - seems to work in evenings.

I checked the elev on sat and tilt - they are 101 and 42 respectively. That's what it says on signal strength

Line of sight is clear. Maybe wind moved it? Or bad connection but I checked and all looks good unless faulty line or connection somewhere

If those are your numbers when it's working then that's definitely a problem. You should have 80s-90s. The fact that they are so low means that any little breeze could almost knock them out. The signal meter will get you close but then you have to fine tune the alignment based on the feedback from the meter. You could still be out of alignment, the mast could be unlevel, condensation in the lnb, and unfortunately on and on. If you want to keep trying to work on this yourself, I would first start off making sure there's no damage to the dish itself (condensation, level, frayed cables). If that is good then start moving your alignment around little bits at a time until you notice the signal strength numbers moving in the right direction.
