- See 'Does not display any message on the front panel' above.
- Check the video output port is firmly connected to the TV or VCR.
- If you are using the RF output, check that the RF lead is connected
firmly to the STB and TV/VCR.
- Check that you have selected the correct channel or Video Output
on your TV.
- If you are using the RF Output, check that you have correctly
tuned the UHF channel of the STB or TV.
- Check the brightness level of the TV.
- See ' No Picture ' above.
- Check the signal level, if this is low then try adjusting the
alignment of your dish.
- See ' No Picture ' above.
- Check the volume level of the TV and STB.
- Check the Mute status of the TV and STB.
- Point remote control directly towards the STB.
- Check and replace batteries.
- Check the LNB ; Replace LNB if necessary.
- Check the cable from the LNB.
- Check the position of the dish; realign dish if necessary.
- Check the connection of Aerial or CATV line.
- If you are using a DiSEqC 1.0 switch, check that you have
connected the LNBs to the correct connections on the switch.
- Check the 'Signal Level' and the 'Signal Quality'.
