What are my statutory rights on this? (Freeview Recorder Purchase)

I bought a freeview recorder on the 10th of December. It has frozen up a couple of times… i.e. it won’t change channel and won’t switch off… so I have to unplug it and start it up again.

This keeps happening and want to take it back but am out of my 28 day returns policy. But the fact is the product seems to be faulty. Am I at fault though now for not taking it back sooner? I didn’t take it back before because I thought it just might be like weather problems or something…

If I can’t take it back has anyone got any idea why this would be happening and if I can fix it at all?

Thank you x
