Attention, DTT channels are changing today: here’s what you need to know

During the night of June 5 to 6, 2025, all channels experienced a signal interruption for a few minutes. Far from being trivial, this outage allowed ARCOM to confirm the new channel allocation for linear television. Since the departure of C8 and NRJ12, confirmed on March 1, viewers had to settle for a black screen instead of the usual programs. Now that the two entities have ceased broadcasting, a majority of the channels have changed their numbers. While the TV boxes and devices concerned automatically updated, human intervention was still required for other devices. But how do you do this?

For aerial antennas

For users of a TV connected to an antenna or receiving DTT via cable, simply go to the device's "Menu", then access the "Configuration" or "Channel Settings" section to perform a search. Be careful, you should favor the "automatic channel search" because searching manually can be tedious. Arcom, in a communication, specifies that the TV's password may be requested. Most often, it has not been changed by users and consists of a series of basic numbers. You should therefore try: "0000", "1234", "1111" or even "9999". It may also be indicated in the machine's manual.

After a few minutes, you will be able to enjoy the new channel organization. To ensure that everything is in order, you will nevertheless need to go to channels 1, 4, 13 and 15. If the channels of TF1, France 4, BFM TV and LCI are accessible, the TV has been updated. Note that some TVs can also perform this operation automatically, but it is advisable to check to ensure that all the channels have been changed.

For DTT reception by satellite

For those who rely on satellite, the procedure is essentially the same. The procedure must also be carried out in the TV menu. Here again, it is the channel search function that allows you to reconfigure the channel organization. You will also have to wait a few minutes to verify that all channels are assigned.
