Region Is there any way to change the region code in this player, preferably to region free as I play dvds from both Asia, North America and Australia.

Laser assembly has lost the ability to focus and play back. Replace unit since repair not cost effective.

When a DVD disc is created, it is encoded with a "Region number." The disc will only play on DVD players with the same Region number - for instance, a Region 3 disc won't play on a Region 1 player.
Region 1: U.S. and U.S. Territories, Canada
Region 2: Japan, Western Europe, Middle East, South Africa
Region 3: South Korea, Hong Kong, Taiwan, Southeast and East Asia Region 4: New Zealand, Australia, Pacific Islands, Mexico, Central/
South America
Region 5: Russia and the former Soviet Union, Africa, Indian
subcontinent, North Korea Region 6: China

There are computer programs capable of remove the region code from a DVD, but the result should be burned on a new DVD. Most players don't allow a change in the region code more than once. So on your player nothing to hack. Sorry

For all other options, please use Google.

Australia is DVD-region 4:

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).

Good Luck.

works on the BDP 2700 -
turn on player without disc. push home button(looks like a house) on remote. enter 1389310 using remote. wait 10 sec then turn off at front of player. wait 10 sec then turn on at front of player.

I believe the 7200 is not able to be unlocked for region free play though

BD media does have region codes. But, unlike current DVD players, the region codes for BD media use letters instead of numbers to indicate a particular zone or region where the discs can be played.

The BD region codes are as follows:

• Region A: North America, South America, U.S. Territories, Japan, South Korea, Taiwan, and other areas of Southeast Asia
• Region B: Europe, Africa, Middle East, Australia, and New Zealand.
• Region C: Asia (except for Japan, Korea, Taiwan, and other areas of Southeast Asia)

region codes are as follow. Region 1 North America, Region 4 South America, Australia, Region 2 Europe, Region 5 Asia Major,Africa,Region 6 Asia Minor, Probably your DVD is from another region....hope this helps

It's not possible to change the region code in the Blu-ray Player.

Q: What is Regional Coding enhancement(RCE)?
A: It's a digital enhancement added to some Warner Bros and Columbia DVDs to stop region 1 (R1) DVDs from playing on Region-free DVD players.

Q: What's the difference between Region Coding and RCE?
A: Regional Coding enhancement(RCE) is an additional layer of protection which some studios have placed on select REGION 1 DVDs to prevent them from playing on region-free or multi-region players. Region Coding is a part of the DVD spec which divides the world into 8 regions:
Region 1: U.S., Canada, U.S. Territories
Region 2: Japan, Europe, South Africa, and Middle East (including Egypt)
Region 3: Southeast Asia and East Asia (including Hong Kong)
Region 4: Australia, New Zealand, Pacific Islands, Central America, Mexico, South America, and the Caribbean
Region 5: Eastern Europe (Former Soviet Union), Indian subcontinent, Africa, North Korea, and Mongolia
Region 6: China
Region 7: Reserved
Region 8: Special international venues (airplanes, cruise ships, etc.)

Basically, DVDs released in each region will typically only play on players sold in that region. IE a DVD released in the UK *Region 2* would not play on a player sold in the us *Region 1*. You can tell what Region a DVD is coded for by looking at the back of the box for a Globe with a number on it. The number correlates to the region list above. If a DVD is listed as 'Region 0' it means that it isn't coded for any region and should play on ALL regions players.

On the top right side of the screen your region code will appear, use the left and right nav keys on the remote to switch between regions, and 255 (there is no 0) for all regions
