SG2100. when the dish is at say 79deg. i can lock on and it is great! i will switch to another sat get that one sweet. go back to 79deg. and have it be off. all parts are tight. when i touch my finger to the dish and apply a small amount of pressure it shifts. there is a small amount of rocking (play) back and forth. when i do that it comes in perfect. i tried to compensate by say setting 79deg. at 78.5 and it works ok. then when i go to another sat, lock on it, then go back to 79deg. which i now have set at 78.5deg.it is out. the play in the motor has shifted during the move. again when i apply pressure to the dish it will tune good. and so on and so on. the cycle is futile. the play is small but it never falls on the same degree each time its moved. it rocks back and forth in any position. i even maybe thought to add a weight on one side. but im not really too happy with this. thanks for trying
