Sparkly pictures can have a multitude of causes. If sparklies are both black and white
then a poor signal is the cause. The tuner module may be at fault but it is possible that the
dish has moved out of line or the cable or LNB are faulty. Of course, very heavy rain or
snow can also cause this fault, as can anything obstructing the dish (such as a tree). If the
sparklies are only black or only white then the tuning is incorrect. Make sure that the
affected channels have the correct frequency set then try the fine tune OFFSET adjust-
ment (described earlier) for the best picture quality on all channels.
Sometimes you can trick the receiver into tuning correctly. If you can’t get rid of white
sparklies, press [tune down] then immediately press [H/V] and wait. If the picture clears
press [Preset] [Preset]. to store it. If the sparklies are black, press [tune up] then [H/V].
No pictures or sound, just a grey screen with "snow":
Probably caused by no LNB voltage from the receiver. Try replacing the 630mA fuse
inside your receiver. If the fuse melts again then you probably have a short circuit in your
cable screw connectors. If the fuse is intact but you can measure no LNB voltage (use a
volt meter with one test probe held on the cable input connector thread and one touching
the centre) then the 6R8 resistor may be damaged and need replacing.
Can’t Tune receiver to TV:
Sometimes the receiver is tuned to a channel which is already in use by a terrestrial TV
station. In this case, pick an unused channel on your TV and turn the screw marked
CH.ADJ at the rear of the SRD400 until the satellite picture appears on the TV screen.
Pictures are grainy and of poor quality or interference on pictures:
Use good quality RF leads made with double-screened coaxial cable. The TV plugs on
these leads must be soldered on.
