Page 1 of Urgent need serious help with my Grundig GDV-520

I just put the region code into my Grundig GDV-520 and now its playing nothing at all. I tried reseting back to region 2 but the only thing its playing is normal music CD`s. I have turned if off at the mains and left it off over night as this is supposedd to reset it but still nothings happening. Im no newbie to region hacking but this one has me stumped....

Any ideas would be helpfull and well appreciated.
