Undocumented fix for DVP-CX995V remote RM-ASP001 not working
I know this product is very long-in-the-tooth, and odds are low that this will help anyone at this point. However, if you have a DVP-CX995V and the companion RM-ASP001 remote is not working, read on... I bought this equipment new and have used it without issue for years and taken excellent care of it. But about six months ago I upgraded my home theatre to all HDMI devices which meant replacing almost everything. However, the DVP-CX995V has an HDMI output (which I had never used). After discovering that it wouldn't work, I then found the firmware update from Sony for this player. I applied it without incident and the HDMI output started working - YAY! :-) Unfortunately, the RM-ASP001 stopped working. :-( I confirmed that the IR emitter was still illuminating (by viewing with my cell phone camera). It seemed virtually impossible that updating the firmware in the player would have caused the remote itself to fail. The only logical conclusion was that somehow the new firmware in the player was faulty and had disabled remote control.
I submitted a support ticket to Sony and they responded with a link to a support article that gave the standard "test your remote / reset your remote" advice. But that was not helpful. Subsequently I bought a Logitech Harmony Elite for my new system. Just for grins I decided to try it with the DVP-CX995V. Much to my (happy!) surprise - it worked! So once again I was back in business. It took me a while to figure out how to use the Harmony to gain control of all the needed functions but I was mostly successful. But it still bugged me that the RM-ASP001 had just suddenly stopped working.
A few months later I decided to take another look. I removed the batteries from the RM-ASP001 and was contemplating disassembling it when I noticed a small switch in the battery compartment labelled "COMMAND MODE". It has three positions: 1, 2 and 3. The switch was in position 2. I moved it to position 1 and reinserted the batteries. And suddenly the remote was working! I haven't bothered to re-test the remote with positions 2 and 3, but I'll assume that either: a) I somehow moved the switch accidentally (how? I don't know / don't think so...), or b) the new firmware did create an incompatibility with the COMMAND MODE "2", but it works fine with mode "1".
I hope this helps someone. The DVP-CX995V is a great disc changer, but much of its functionality becomes difficult - or impossible to use without a remote. FYI, I've submitted this information to Sony via the same means I used to originally report the problem. Hopefully they will update their support article to include it should anyone else inquire in the future...
