Philips 32HFL5870/10 LCD- Can't remove subtitles

[downunder]

Hi folks, Customer brought the above model in, no remote (but I have a couple of Philips remotes that work it) and no user manual.

Unfortunately, subtitles has been activated, and I have been unable to remove them. I've done a factory reset but they're still there.

There is a Subtitle item in the menu, but it seems to do didley squat. Any ideas?                         Bruce
