rrob,
Yesterday, I had problems like you posted in an earlier post.
Whenever I moved my KU-dish my S10 would reset.
I ordered the SD 4844 from ebay/china to have the part handy and it arrived 1 week ago.
Yesterday when I had the problem, I suspected that it was the chip in the power-supply.
Today when I opened up my S10 it had the SD 4843 on the power-supply.
I replaced the SD 4843 with the SD 4844.
I moved the dish many times now and the receiver did not reset.
Looks like the SD 4844 will work.
