Common VAST Error Codes

E-50-32 No service available

In most cases, you will see this error when the user has pressed EXIT while the decoder is displaying the SEARCHING FOR SIGNAL message.  Simply press the RESET button on the front of the decoder (behind the smartcard door of Humax brand) and the decoder will return to the search screen.  If it remains on this screen then either the dish is not aligned OR the LNB settings within the menu are set wrong.  Enter the INSTALLATION menu within the main menu and ensure that the LNB L.O frequency is set to 10.700.  In order to receive ALL services/channels on the VAST platform, a 10700 LNB is required.  When set to 10.700 ensure that you have at least 65% signal QUALITY on the screen and then perform a re-scan.

E48 - No signal

There are a few possibilities here.  Regardless, the decoder is not receiving signal from the dish.  This could be due to (in order of most likely):

  • The dish is not aligned correctly. You can check this by entering the INSTALLATION menu and ensuring you have adequate SIGNAL QUALITY.  The easiest way to check alignment is to use a digital satellite meter.
  • If you have a digital satellite meter that is programmed for the Optus C1/D3 that confirms you are aligned then your decoder settings are incorrect.  Enter the INSTALLATION menu and ensure that the LNB setting is set to 10700.  Also, perform a factory default to reset the default search frequency.
  • Check the skew of the LNB.  The LNB on the front of the dish should be rotated to the correct position for your area.


This isn't a message generated by the VAST decoder but rather by your TV.  Either your TV is on the wrong AV channel ie HDMI/composite/compnent etc OR the VAST decoder is on standy and displaying the time.

If you activated as a traveller, has it been more than 6 months since you last registered the card?  If so, call 1300 993 376 and speak to one of the VAST operators who will switch your card back on.
