I own an LG (LH-W750TA) DVD player that is set for DVD region 4. I am after an unlocking code to allow me to view DVDs from region 1 NTSC.

You can try either of these solutions as there does not appear to be a specific instruction for the DVD21:

Harman Kardon DVD1 / DVD5 / DVD10 / DVD20 / DVD50 / DVD1500 1. Player has to be in standby mode, no disc in tray
2. Press 3, 1, 4, 1, 5, 9, 2
3. Enter region (1-4)
4. Press OPEN, insert a disc

Note: Region is saved, you will have to set the RC every time you want to watch another DVD.

Harman Kardon DVD22 / DVD23 / DVD31 / DVD47 / HS100 HTS
1. Switch on
2. Press OSD
3. Select "Setup"
4. Enter 3, 1, 4, 1, 5, 9, 0 (the last number is the region)

See below region codes. It appears Harman Kardon only support 1-4, but it is worth trying 0 and seeing if it works.

First, see if you can find out what type of DVD it is PAL or NTSC. The difference (You need to keep this in mind when selecting your region):
NTSC: usually associated with the United States, Canada, Japan, South Korea, Mexico, Philippines, Taiwan, and other countries.
PAL usually associated with Europe, most of Africa, China, India, Australia, New Zealand, Israel, North Korea, and other countries (and Brazil, but using the refresh rate and resolution commonly associated with NTSC).
-------------------------------------------------------------------------------------------
0. Informal term meaning "worldwide". Region 0 is not an official setting; discs that bear the region 0 symbol either have no flag set or have regions 1-6 flags set. Region 0 is commonly referred to as "Region Free", especially when talking about DVD and Blu-ray Disc players.

1. United States, Canada, Bermuda, Caribbean, U.S. territories
2. Europe, Middle East, Egypt, Japan, South Africa, Swaziland, Lesotho, Greenland, French Overseas departments and territories
3. Southeast Asia, South Korea, Taiwan, Hong Kong, Macau
4. South America, Central America, Mexico, New Zealand, Australia, Papua New Guinea and much of Oceania
5. Bangladesh, India, Nepal, Afghanistan, Sri Lanka, Ukraine, Belarus, Russia, Kazakhstan, Pakistan, Africa (except Egypt, South Africa, Swaziland, Lesotho), Central Asia, Mongolia, North Korea
6. China
7. Reserved for future use, MPAA-related DVDs and "media copies" of pre-releases in Asia
8. International venues such as aircraft, cruise ships, spacecraft, etc.

ALLRegion ALL discs have all eight flags set, allowing the disc to be played in any location, on any player.

Good Luck.

DVD REGION FREE & BLUE-RAY REGION FREE
To changethe Region code on your DVD player, open Control Panel - System - Hardware -Device manager, and click on DVD/CD ROM drives, then right click on the DVDdrive and click Properties then click on DVD Region.
You can enter a new region and it also shows you how many changes have beenmade.
NOTE you can make only 4 changes and the player will lock permanently on the4th change.
If you want to play DVDs from any region you maybe able to upgrade the firmwareto make it region free BUT if you make a mistake or installed the wrongfirmware the player will be a piece of junk.
The best solution to make the player region free is to install a piece ofsoftware (Passkey for DVD) that allows you to play DVDs from any region andPasskey for Blu-ray that allows you to play Blu-rays from any region. There areseveral available on the Internet but my favourite is DVD-Region Free From:-
www.dvdfab.com/products,free.htm

Solution detailed below.

Using the Remote:
1. Power On
2. Open Tray
3. Press Pause
4. Press 0000
5. TV will show blue screen with the following two lines:
a. Region Edit:
b. Region Code:
6. Enter 0 in Region Edit line (for Region Free)
6. Press Enter
7. Press Pause
8. Power Off

Please leave feedback

Cheers

The geographical regions are as follows:
REGION 1 -- USA, Canada
REGION 2 -- Japan, Europe, South Africa, Middle East, Greenland
REGION 3 -- S.Korea, Taiwan, Hong Kong, Parts of South East Asia
REGION 4 -- Australia, New Zealand, Latin America (including Mexico)
REGION 5 -- Eastern Europe, Russia, India, Africa
REGION 6 -- China
REGION 7 -- Reserved for Unspecified Special Use
REGION 8 -- Reserved for Cruise Ships, Airlines, etc...
REGION 0 or REGION ALL -- Discs are uncoded and can be played Worldwide, however, PAL discs must be played in a PAL-compatible unit and NTSC discs must be played in an NTSC-compatible unit.

The end result is that DVDs encoded for regions other than Region 1 cannot be played on a region 1 DVD player, also, players marketed for other regions cannot play region 1-stamped DVDs.

Hope this information is useful to you.

To unlock the DVD code its defends upon what region you belongs or from were you bought the DVD unit. Just click this site to hack the region code ; http://www.videohelp.com/dvdhacks

To keep it simple, this means that DVD players and DVDs are labeled for operation on within a specific geographical region in the world. For example, the U.S. is in region 1. This means that all DVD players sold in the U.S. are made to region 1 specifications. As a result, region 1 players can only play region 1 discs. That's right, the DVDs themselves are encoded for a specific region. On the back of each DVD package, you will a find a region number (1 thru 6).
The geographical regions are as follows:
REGION 1 -- USA, Canada
REGION 2 -- Japan, Europe, South Africa, Middle East, Greenland
REGION 3 -- S.Korea, Taiwan, Hong Kong, Parts of South East Asia
REGION 4 -- Australia, New Zealand, Latin America (including Mexico)
REGION 5 -- Eastern Europe, Russia, India, Africa
REGION 6 -- China
REGION 7 -- Reserved for Unspecified Special Use
REGION 8 -- Reserved for Cruise Ships, Airlines, etc...
REGION 0 or REGION ALL -- Discs are uncoded and can be played Worldwide, however, PAL discs must be played in a PAL-compatible unit and NTSC discs must be played in an NTSC-compatible unit.

DONT FORGET TO RATE;

HI,
it depends on whether the drive is multi-region ?
Some drives are region Set, i.e Region 1 ( NTSC-USA )
Region 2 ( UK PAL )
Most Players Are Region Set, To the country they are purchased in, you can sometimes set the player to become, multi-region, via various buttons on the remote or by the front panel.
I offer a service to unlock 99% of DVD Players, to play all or many regions.
We do have a charge for this Service.
Many Thanks mike @ Compurepair.

1. Power on the player with no disk in the drive

2. Press "PAUSE" on the remote

3. Enter "3 1 4 1 5 9" on the remote (the word COdE appears on the display)

4. Enter "0" on the remote (0 = All Regions, 1 = Region 1, 2 = Region 2, etc.)

5. Press "PAUSE" on the remote

6. Power the player off and then back on

Try this (for a LH-T360SE)

Open disk tray and press 0000, a two line menu appears with "Edit Region _" and "Region Code:x" put in required region (presumably 0) and press enter. Region Code:0 appears. power off and enjoy.

region code 0 is No region restrictions.
