Just posting to confirm that another Mitsubishi 3DA-1 with a build date of January 2011 works with this trick on my 61A650. I bought it off of eBay and asked the seller for the build date before purchasing. It was right on the edge of confirmed working build dates, so I was a little nervous, but I would have turned around and sold it back on eBay if it didn't work. I think somebody else bidding on the 3DA-1 knew that it should work with a Samsung DLP set since it was bid up well above retail value of the box, which you can purchase new on Amazon. Of course, Amazon probably has newer stock and you don't know what you're going to get, so it is worth more than retail for Samsung DLP owners.
Thank you for this forum and this thread for saving me at least $130. I'm very happy that the 3D ready set that I bought nearly 4 years ago is finally capable of playing 3D content from my PS3! I'm using the Ultimate3DHeaven Ultra-Clear DLP Link glasses by the way, which are working well for me!
