It is actually on a “STRONG” motor which sadly does not move (but that’s another story) and therefore I just keep it stuck on 13 degrees. I generally have a good reception of around 85% in signal strength and quality and no BER errors.In the past month or so the following has been happening on an on and off basis: CASE 1: I will be watching a channel, and then all of a sudden the signal strength and quality both drop to below 50% and I get errors in the hundreds. Once the problem occurs it affects most of the channels except 2 or 3.  The channels that continue to work are one the same frequency (same transponder). Channels on all other transponders are lost. CASE 2: I will be watching one of the “problem channels” without any issues, and then if I switch to one of the non-problematic channels, when I switch back to the “problem channels” the signal is now lost.  Sometimes the issue is resolved by a restart, and sometimes after flicking through the channels going back and forth between the problematic and non problematic channels the problem is solved temporarily. But this is never a permanent solution.A couple of days ago the problem happened again and nothing I did worked, when all of a sudden I thought about fumbling about with the cable that comes from the dish and goes into the decoder. After I moved it around and wiggled it for a bit it worked and I was back in business.  The problem still occurs, although I seem to have found a more “reliable” solution to it <img src="https://www.satellites.co.uk/styles/default/xenforo/smilies/smile.png"  class="smilie" loading="lazy" alt=":)" title="Smile    :)" data-shortname=":)" />My question is what you think might be causing this problem? Is it my lnb? Is it my tuner? Is it my power supply? I did borrow a friend’s DM500 which seemed to work a bit better, although the problem did occur with this decoder as well, but maybe not as often as it did with mine. Any suggestion would be much appreciated. Thanks very much.</blockquote>
