Where do I get software update for Sharp hp21u blu ray?

You should have an option in the menu which says Update Firmware, failing that the Sharp website will have the update which can be burnt to disc and inserted into your player.

I have the same problem but I did download the updates for both my Sony and Sharp Blu Rays and Avatar played wonderfully but unfortunately a few days later both players stop playing all Blu Rays. Has anyone had the same problem?

My advice is to contact the company that makes the unit and ask them if it requires an upgrade. Let me know what they say so i may advise further. Thanks.

my sharp aquos will not play certaian blue ray I've exchanged the the disk a couple of time...are there any updates that I need

Verify version of the firmware, if it is older then PN9062300, you will have to upgrade it. Newer version of the firmware can be found here. For instruction on upgrade procedure refer to the owner's manual.

Hello, we had the same problem with District 9. If your in uk you need to go to http://www.sharpelectronics.info/Software.aspx, select the sharp bd player make e.d. BDHP21H and select download to your desktop. If you not in uk go to the sharp web site relevant to your country. Once download is complete you need to extract files (they are zipped). In our case there were three files downloded, one being directions, the 2nd the actual software update and the 3rd something th do with version numbers. Once unzipped copy and paste the file ending in .RVP only to your usb/pen drive. Now insert the usb/pen drive into the bd player and follow the set up instructions. IN the case of our bd player (which is a different make to yours) we selected set up, software update and then just followed the directions from there. But probably best you follow the instructions given by sharp on thedownload. Best of luck.
