have a portable satellite for my camper. Have vip 211z receiver. Dish is turbo had dp plus no. A221201 WA080RCWF . Been leveling tripod adjusting for 2 days now. Coax checked ok. Finally got signal strength 25 on 119 and 0 signal strength on 110 and 129. No obstructions. Wide open blue sky. Checked adjustments and moved 2 to 4 degrees with not much help. Would u think the LNIB broke. Can I replace it and with what.
