While the service was upgraded to give more people access to channel Five, it’s been reported nearly half a million households will lose access to ITV3 and ITV4.
Even worse, it’s thought 20,000 set-top boxes from makers such as Daewoo and Bush will have stopped working altogether after the upgrade.
A Freeview spokesperson has said viewers with problems should simply try again.
The statement read: "The majority of people find retuning straightforward but if viewers are experiencing problems after retuning, we would suggest trying again."
If you were thinking about calling Freeview for a bit of advice, you might want to give it a miss. Freeview is reporting more than 200 calls a minute to its helpline, with many callers being told no more calls were being accepted due to “high call volumes”.
Not helping the situation, Freeview has also admitted that its website is crashing under the pressure of people logging on for advice, and is only working “intermittently”. Handy.
