How much DC voltage do you have at the receiver's lnb port? Check both polarities.
By Chance, have you checked and made sure that lnb power is set to ON in the antenna setup menu?
none at lnb port + or - yes checked more than once on settings . sorry my one b tton not working was p shing pretty hard k_ dish and lost lnb and motor power maybe throw in wb?
Maybe....
Wait a couple of days first and see if anybody else here has an idea for you!
ok and THANKS!!
There are 2 capacitor to look for on the Power Supply, C19 and C17 and the 4 pin small IC SD4844. Also, it will help to change the poly switch F1993 from Digi key. All parts together less than 10 bucks
there is no c17 orc19 and the 4 legged ic isEL817 c209 if i read it right . as far as i can tell all leads from board have right voltage,looped o_t of pansat and it works that way
With your volt meter check for lnb voltage on both legs of F1 (polyfuse) with coax dis-connected. If ok connect coax and check again. Post results in here.
ok did I that, nothing lnb hooked,maybe .5v not hooked also nothing on LM317 this box is not 1 year yet so I think power board is a little diff. have been over all caps , have not taken to test yet maybe next step?
