I have a dvd from England and my old Sony DVP-C670D keeps giving me a prohibited message4 every time i try to play it. How do i unblock the region code.

Hi there,

Although no guarantee, this 'region hack' is rumoured to work:

1. Place the DVD player into 'standby' mode.

2. Using the Sony remote, press the following button sequence: Title; Clear; Power (green button); 0 (zero button)

3. Using the remote, Open the disc tray, then close again.

Now insert your disc and attempt to play - allow up to 2mins to load/play. If no response, open/close tray and try playing disc again.

Does not play when disc entered nor when play is selected. (XD-E500KB)


Push in the plug connected to the "Video Out" jack on the rear of the Dvd to ensure it is connected firmly. Check the connection at the back of the TV as well.

Press the "Source" or "Input" button on the TV remote to verify the television's input is set to the DVD connection.

Press the "open/close" button on the front of the DVD to open the disc tray. Insert and test different DVDs to determine if the problem is with a specific disc, or if the player will not operate.

Eject the DVD tray and insert the DVD laser lens cleaner. Close the tray and wait a few seconds for the cleaning disc to load. Press "Play" on the front control panel to spin the disc through the cleaning cycle.

Remove the cleaning disc, insert a DVD and test playback operation. If the machine still will not play discs, the main receiver unit may require internal repairs best left to an experienced technician.

Dvd slider door won't close.

Hi, is it fully open, or just partially open?
Is it nearly shut but just jammed? If so have you tried inserting a flat peice of plastic and pulling the draw open. You could do this with no power to the dvd player, It might be that you haven't inserted the disc properly and it is wedged in.

Try all this and see how you get on.

Can i make it region free?


Turn on your DVD Player

Press OPEN on remote

Press 1 3 7 9 and the number of the region you want to use between 0 and 6. Use 0 for region free. You may need to press these buttons slowly. You will see XXXX on the TV. When you press the last number, it will display at the top left of the screen.

Now insert a disc (other than your own region) into the player and close it. It should load and play. Other region discs should play as well. If you didn't do it correctly it will display "Wrong Region".

When you turn off the DVD player it will keep the settings.
