Thousands of television viewers have been forced to buy new digital TV equipment after a Freeview upgrade rendered 1% of its set-top boxes obsolete.
Freeview has estimated that 230,000 of the 23 million Freeview boxes sold to date would no longer work.
Models made before the industry-standard digital tick logo was brought in in May 2006 have been affected.
Rob Farmer, Freeview's director of marketing and communications, said 1,200 calls had been made to Freeview and manufacturers - far lower than expected - during the upgrading process, which ended last week.
"It seems the majority of the older models were no longer being used or had been replaced," he said.
"Having said that, we have done everything we can to help those people who have been affected."
DMOL, the company which manages technical changes to the Freeview platform, carried out changes to the network region-by-region between the end of May and August 5.
Some models made by Bush, Daewoo, Labgear and Portland and Triax were affected.
Freeview said the upgrade work to the UK's 80 main transmitters was necessary to enable them to send increasing amounts of data to people's set-top boxes.
