Have tried this Code to unlock my Region 2 Samsung HT-ds100b 5.1 Home Theatre DVD Player.
eject any dvd’s then:-
- turn off player (at the wall) wait 30 secs til completely powered down
- turn power back on
- use remote to turn player on and wait for it to power up (will likely show DVD on the display)
- Press “Enter” on the remote
- press in sequence " 8, 4, 2, 6, 9 " on the remote
- then press “Enter” on the remote again
"dvd player turn itself off, I powered it up again and it will not play any of my DVD disk. I tried VCD Disks and this plays.
All disks played befor I changed the code.
