metronic accessbox
hi !
I have a Metronic Accesbox FTA sat receiver with a problem to solve.
When i connect it directly to a sat dish with a single or dual lnb it will not receive any signal (pointed to hotbird 13E) except for some arabic channel.Others like Italian bouquets etc can't find any signal ( 0%) and finally some other channel like euronews do find signal (89%) but the screen is black.
Also i connected it to a motorized system and discovered that it doesn't drive it no matter whether Disecq 1.2 is enabled or not.
When i connected it to the LOOP THROUGH output of another receiver it worked
perfectly.So it can receive and decode correctly, i'm thinking that the trouble begins when it has to supply directly the LNB (power supply of LNB).
I measured the dc output from the sat antenna jack and it showed 21.8 V,did the same on different other decoders and got around 18 v. (Polarity voltages are 13v/18V i know but then what is this 21,8 V that comes out since using the loop throug of another receiver as input for this works so 22Khz tone burst is ok and also signal receiving )
And i checked the internal power supply voltages and everything seems fine 3.3v
5v 12v 22v 33v.
Someone skillful could help me (i'm not a serviceman of sat receivers nor i have ther service manual)....
Maybe someone has the service manual...please help is welcomed!
