Are you finding the satellites on the same two lnb's or are they moving around.
That is when you find 119 and 110, does you checkswitch info look like OK|OK|X, and when you find 119 and 129 is it the same (the X may be on either end but does not swap). May be an lnb problem not alignment.
First disconnect all sat cables and run a check switch to clear the switch matrix. Reconnect and run checkswitch again.
Cover both outer lnb's with tin foil, set your skew to 112 and find 110. Be sure the Point Dish screen says you are locked on 110.
Uncover both outer lnb's and see if you get signal on either 110 or 129. You should get both, if not get the faulty lnb replaced.
You may need to de-tune 119 and 110 to peak 129 for stable reception.
