Dish Network - "Aquiring Signal" problem trouble shooting ... anyone ? anyone ?

a friend of mine is at home and her tv in her bedrooms only telling her "aquiring signal, yet he moms in the living room watching TV

im assuming they would have to have a dual head sattilite dish setup, but the hell if ive ever payed attention

she says the progress “goes from 4/5 to zero again”

anyone know if there a proceddure to go thru to see if she can correct the problem herself b she has to call DN and prolly pay to have it all fixed ?
