The previous agreement between the parties expired on Friday without them being able to agree, but Comhem's customers were then given the opportunity to continue watching the TV4 channels until the night before Monday.
Unless an agreement is in place before then, Comhem will turn off the channels for 2.1 million customers.
The conflict is about Comhem not accepting that TV4 has raised the price of the new agreement.
However, Comhem has chosen not to comment on how big the price increase is, or how TV4 justifies it.
In December last year, Comhem's and Boxers' customers had to do without TV4's channels for ten days because the parties did not succeed in reaching a settlement before the then agreement expired.
