I hunted around for the player’s instructions, and amazingly found them under a pile of DVDs. It turns out that Blu-ray regions must be selected manually using colored buttons on the remote.
I tried to delete my original post, but got an error saying I’m not authorized to do that, so here’s the text of the original message I posted an hour or so ago:
A few years ago I bought a Sony BDP-S3700 Blu-ray Disc/DVD Player which had been modified to be “Region Free.”
A bright green label stuck onto the box claimed:
Play any Standard DVD Region
0, 1, 2 ,3 ,4 ,5 ,6 ,7 ,8
Play any Blu-ray DISC A, B, & C
So far it’s played imported DVDs without any problems.
But this month I bought a Blu-ray disc from England, and when I try to play it I get this error message on the TV screen:
THIS BLU-RAY DISC WILL PLAY BACK ON REGION B PLAYERS ONLY
I’d be grateful for any ideas on how to troubleshoot this problem
