I've recently moved into a flat and found one of these receivers (Prosat P-8000S) in a draw. There's a dish installed that I believe was once used for Sky (the draw also contained the manual for a sky-branded receiver), but can't get it to receive anything.

The settings I used (entered via "add xpdr") were (other options are listed in {} braces):

LNB Source: LNB1 (11300)(11300)
{LNB2 (09750)(10600)} {LNB3 (10750)(10750)} {LNB4 (05150)(05150)}

Satellite: User1
{Intelsat 804, ASIASAT_2, ST_1, ASIASAT_3S, PALAPA_C2, JCSAT_3, THAICOM_2_3, AGILA_2, PAMAMSAT_8}

Transponder: 12483 (also tried 12456)

Symbol Rate: 22500

Polerization: Horz
{Vert, Left, Right}

0/12V Mode: Off

DiSEqC: Off

Skew Control: Off

Skew Steps: -90

Search Mode: Transponder

When I press OK after editing/adding one of these, it gives me a "Service list is empty" message/error.

It shows a signal strength of between 174 and 210 (usually 174, but changes occasionally), but signal quality rapidly fluctuates between 0%, ~50%, and 100%. When at 0%, it shows a red "UNLOCK" message above the bars, and a "P_ERROR RARE" of ~20% when at 50% or 100%.


Any suggestions as to what the problem is or what I can do to try and solve it?
