9. TROUBLESHOOTING

1. No Video/Audio, Channel not found when Scanning
a. Ensure that your TV is 1080p Full HD or 4K UHD and has a DVB-T Digital Tuner.
b. When doing a scan, please ensure you have selected the Digital Scan / Search option. Analogue Search will
not find the TM-RF HD IR.
c. Try a different Channel Number. Check that the channel number is not conflicting with your local
transmitter, for example, in London BBC 1 is on channel 23 so if you selected Channel 23 in the TM-RF HD IR,
it would not work.
Furthermore, check that the selected channel number is not conflicting with other transmissions such at
4G/LTE (normally above Channel 61).
d. The software in your TV may be out of date. Please update your TV to ensure it has the latest software. This
is normally found in Settings or Maintenance menus.
e. Try a different HDMI cable.
f. Disconnect HDMI cables, any cable going into RF IN, leaving only RF OUT connected. Try another scan.
g. Please check your country is selected in Menu – Stream – Country.
h. If you have connected an aerial / antenna to the RF IN, please remove it and try another scan on your TV to
see if it shows the vide.
If this works without the aerial / antenna connected, please try 1.i. below
i. Different channel numbers have different dB signal strengths. Furthermore, if using an amplifier or powered
splitter, this will affect the dB too. If the dB is too high, there will be no video or the channel may not be
found.
The output signal from the RF OUT may be too high or too low as a result, therefore please adjust the dB in
the Menu – Advanced – dB Level by for example, -5 dB, -10 dB and then rescan the channel.
j. Ensure that your TV's DVB-T tuner is compatible with MPEG-4. If it is not, you will require a DVB-T2 Set-Top
Box for the TM-RF HD IR to connect to in order to make the modulator compatible with your TV.
k. Try a Factory Reset and scan again.
2. LCN not working
a. Ensure that your TV supports LCN.
b. Check that LCN is ON in your TV
c. Ensure that LCN you entered is free in your TV's EPG.
