Hello everyone....I have been browsing the forum looking for tips on fixing some recent 771 errors. I have a Slimline 3 dish going to a Zinwell 6x8 multi-switch. It then goes to a HR24 DVR and to a standard SD receiver. The system is 3 years old or so at this point. The problems started a month ago with some scrambling or freezing when watching live TV, this occurred on both receivers. It then escalated to 771 errors when watching live TV, you would also have recorded programs on the DVR error out by saying it didn't record due to reception issues.
I started by checking the satellite strength, everything still looked good with virtually all transponders being over 95 and a good signal strength on both tuners of the DVR. The problem then got worse about 2 weeks later, I checked and found all the even transponders on the 101 and 99 were showing zero on the SD receiver and tuner 1 of the DVR, for some reason tuner 2 still showed a great signal strength. When I tuned to the test channels 9501 said 13v and 9502 gave a 771 error, 9503 was good, 9504 failed.
My next step was to check the cabling, everything looks good as far as I can tell. I tried to test things by swapping the cables at the switch for the 13v and 18v inputs on the 101/99 inputs . The problem briefly fixed itself completely, I had good transponder numbers on the SD receiver and on both tuners of the DVR. I checked all the test channels and got a passing on both 13v and 18v.
I found this morning the problem was now back and worse than ever with 771 errors on multiple channels. I checked the signal and found 0's on all the odd transponders for the 101/99 on both tuners of the DVR and on the SD receiver. When I scrolled through signal strength on the DVR it showed no signal on both tuners on all transponders, not just the odd ones. The transponders on 103 seemed to have good levels at the time. I went back through dish setup and it failed on odds for 99 and 101 and evens on 103.
I initially assumed since the problem has moved from the even transponders to the odd transponders on 101 that the problem was simply with the RG6 between the switch and the LNBs. However, I still can't explain why when I originally had the problem with the even transponders tuner 2 on the DVR still showed excellent signal. I also don't understand why the DVR had no signal on any transponders on 101 today and why it now has an error on 103. Any advice?
