Start with the account task you intended
The 5 Preference Centre supports editing details such as name, email, date of birth and postcode, as well as password changes and account deletion. Its help article places these controls on the website. If the television app has no matching editor, repeated searches through picture or playback menus will not necessarily find it. Open the account-management route on the broadcaster website instead.
Expect a sign-out after a password change
The broadcaster explicitly identifies automatic sign-out after changing a password. Losing the current signed-in page at that point is therefore not enough evidence that the new password failed to save. Return to the official sign-in page and use the updated credentials. Do not cycle through several new password changes simply because the old session ended as designed.
Keep deletion separate from routine editing
Account deletion is offered in the same area, but it is a different decision from correcting a postcode or replacing an email address. Read the selected action and its confirmation screen before continuing. If all you need is an updated account detail, choose that specific editor. Do not use deletion as a routine fix for a missing programme tile or a television playback error.
Check the result you can actually observe
After signing back in, verify the particular detail you changed and whether the intended account is open. A successful login does not by itself confirm a postcode or email edit. If the editor fails, provide support with the affected field and the displayed error, without including the password. 5’s help directs viewers who cannot access or change account details to its support team.
