Sounds like the motor may have been reset when the pointer was not in the 0 (zero) position.
Manually drive the motor to the 0 (zero) position and insert a paper clip in the motor reset and hold until the LED turns solid Green.
Verify that the mounting post is PERFECTLY plumb. If it is not, the satellite arc will be difficult (if not impossible) to track.
Set the motor latitude setting to match your latitude. Set the dish elevation setting to the setting between 20 and 30 degrees as listed in the install manual for your latitude. Aim the motor so the arm is aimed approximately to magnetically corrected True South (This only need to be close). Set the LNBF rotation to the centered 12 o'clock position. The cable will be aimed straight down.
Factory Reset the receiver.
Select Satellite AMC4 / LNB type Universal 9750/10600/Motor USALS/ Enter your Logitude as WEST and Your Latitude as NORTH. Select GoTo the satellite position. Exit and save settings.
Select satellite AMC4, select TP 11822 H 5700 (or similar frequency), LNB Power ON. Motor should have moved to the correct calculated position. Slowly pan the motor left or right 10 or 15 degrees on either side of the calculated motor position. If no signal quality is detected, increase or decrease in one degree increments and repeat the panning process until the satellite is found.
Once the satellite is found, scan in a few channels to save the position.
Select satellite Galaxy25, TP 12177, Motor USALS, LNB type Universal 9750/10600, Power ON. Select GoTo satellite position. Exit and save changes.
Select satellite Galaxy25, TP 12177. You should have Signal Quality. Make sight left / right motor rotation on the post or elevation adjustment to the dish until the Signal Quality is peaked.
Repeat the above process for an Eastern satellite and a Western Satellite, making slight Panning Left/Right motor adjustments and slight Dish elevation adjustments to peak for each satellite until the motor tracks the arc perfectly.
