None of the tips helped? A total reset is not the fix.
Not knowing what kind of equip you have doesnt help, but I wolud say that your problem is a "dirty" code.
99 percent sure. But since NONE OF THE TIPS ON THIS SITE work I guess you are out of luck.
Well, not really but.....

Very interesting, I just put a post in on this very same subject, i.e. my 3000 locking up on my Marantz CD player and only that component. When you reprogramed did you use "learning" or the code?
I started with the code put switched to learning when the code wouldn't do anything at all.
thanks

I have the same problem with a Marantz CD player. Wondering what you mean by a "dirty Marantz code" and particularly the part about "relearning with a long burst"? How do I do that?
Unit is great except for this little glitch.
Many thanks

Whoops, never mind my last, I'll keep reading your threads.

I bought yesterday a RM-AV 3000 commander here in Brazil and experienced 3 times the very same problem. Whenever I push the Menu or Exit buttoms, the unit stars sending codes continuoslly, but none of my equipment experienced any change. I have a Philips DWIDE TV, DIrect Tv receiver, a Panasonic VCR a SOny DVD player and a AIWA audio system. I yanked one battery and suddenly replace it and lost only day and time.
I would like to know if there are several versions of the commander. Plus, some eletronic equipment, like cellular phones,are able to show it´s firmware version. I would like to know how can we that on this SOny.

I was having this problem before with my Dish Network Model 4900 receiver. When I change to the Model 6000u receiver the problem went away. Now I just upgraded my A/V receiver to a Marantz SR7300 and I am now having the problem again. With the Dish network reciever the problem ocured when I scrolled through the channels. I have not figured out with key has caused the problem with the Marantz yet. Anyone eles out there having this problem with a Marantz A/V receiver, and have you been able to fix it.

Marantz equip is kinda quirky, relearn the marantz functions to the 3000 with a long burst (wait until the 3000 beeps). I'll play around with one at work at let you know what I find out.

I actually reprogramed the volume controls for my Marantz reciever with short burst and it has been working now for three days. Knock on wood!!!

Got my remote about a 1 week ago and I have no option, after reading this thread but to return the POS. I get the continuously transmitting bug with a plinius 8150 amplifier on either vol up or down.

Now if my my mother-in-law used this and it locked on vol up it could result in blowing my $6000 speakers because she is an idiiot and would not know to point away from the amp. Sony makes some good stuff but this is crap, i can't believe the review here did not expose this remote for the crap it is. Lousy ergonomics and it does not work.

In my experience, this problem relates to individual keys, and there are two cases that will cause the remote to lock in transmit mode:

1. Pressing the key twice in succession, or very shortly after a different one.
2. Pressing and holding the key.

In both cases, this is down to the way the command has been learnt. Different methods work for different remotes, but try each of the following:

1. Wait three seconds after pressing the key to learn on the AV3000 before pressing the button on the device remote, then hold the key until you hear the beep.
2. As above, but give the key a brief tap.
3. As 1, but, rather than waiting three seconds, press and hold the key as soon after pressing the key to learn on the AV3000 as possible without it saying "NG".
4. Point the device remote away from the AV3000's receiver, hold the key to learn on the device remote, press the key to learn on the AV3000, then align the two remotes.

However, there is only one way to ensure reliability every time: teach the command to another learning remote and make the AV3000 learn off that.

cb1, you responded to a similar message I had in another thread regarding #2 Sony no good... and it was no good. I have no exotic components, and I have an RM-AV3000 from when it was first released whenever that was. The #1 Sony has NEVER locked up, NEVER lost its programming. There was no "20 second rule" and I first saw that idea in this forum and wondering how it is that my 3000 never, ever had lost anything. Not only that, I changed the batteries so quickly a couple times not even the clock lost the time. Then a few weeks ago I bought a second RM-AV3000 to backup the first. At least a lockup a day, sometimes 3 or 4, stuck in transmit. I tried teaching it all over and not just duplicating the first remote all at once. It still locked. #1? Never. Something has changed in the time since the remote was first released, and it's not for the better. I took it back; the dealer put it right back out for sale, and I asked a salesman not to do that - that I had tried everything, had lockups and that's why it was returned - it wasn't because I didn't like the remote. He took the box and pasted a label over the return label "locks up" and took it off the sales floor. I'm sorry to see this happen, but it's happening, and once again, I never had any problem with the original. Bill Halvorsen

I agree, there is a quirk in some of the 3000 remotes.
When they first came out we had some "lock up" and "lost memory" issues, but since the 20 second rule has been applied, not much of a problem.
When I found out about the 20 second rule I tried some test on three different remote, one that had locked up, one that never had any problem, one straight out of the box. I programmed some stuff in all three took out batteries and immidiatly put them back in, severall times I would say 7 out of 10 times remote retained all memory the other 3 times it lost all programing. I did the same thing again except I lefrt out the batteries for 20 seconds, NEVER lost any programing this way. Since then I always tell my customer about the 20 second rule, live by it with my two remotes, and the one I use a work that has aBUNCH of discrete codes in it.
All I'm saying is that if you wait the 20 seconds then you wont have any problems. Now about the lock ups, If you did a transfer and the second remote locked up then I guess this is just one of those quirks that sony wont admit to having.
I have even taken a remote that lock up or lost its programming due to not following the 20 second rule, or a dirty code, back to the store and used it there for several months with no problem, I guess I just been lucky.

To clarify, I reset #2 RM-AV3000 after the transfer from #1, and started to set it up the hard way... and it locked, and sometimes I would think it would lock up on the same button, but the next day - a different button, and so on. Something is bad wrong in Sonyville.

When I had the same difficulties after resetting the remote and setting it up slowly, I couldn't get anywhere - I'd go to test my progress by using it - and lockups. There must be a capacitor storing a little power that was there and isn't there now - else I couldn't quickly replace batteries and not even lose the clock. #1 has never, ever lost its programming. That they do now speaks of a change somewhere in manufacturing.

Another trick you can try is to take advantage of the ability to generate "micro-macros". You'll probably have a remote somewhere that has a button on it that doesn't do anything for a device. Immediately after pressing the key that does what you want, press the "nothing key". That should make the AV3000 behave under any circumstances.

I picked that up when I was trying to program the remote from a Grundig GDT2000 Freeview receiver, which is a notoriously difficult remote to learn commands from (you can press each button once, but subsequent presses aren't recognised by the receiver, for example: you press Power to turn it off, you have to send the receiver something other than Power before you turn it back on again). Tacking a quick press of the TV Mute button (which only works for Grundig TVs, and I don't have one) on at the end of each learnt command solved the problem.

It's apparent from this thread that there is a problem with this remote which is not "dirty code"
Yes, I have a Marantz Rcvr. I do not use a code I had it learn eveything except how to behave. I have gotten everything to work except the volume control. My problem is with volume up normally, but for the first time today it was volume down. But these "tips and tricks" short burst, long burst, delete all, re-enter, do not work. This remote is to AV remotes what Microsoft is to computers. This is Sony's version of the "Blue Screen of death" "Just reboot it happens".
I have found a temporary solution. I hold it in one hand while I use the remote that came with my Rcvr to control it. Don't get me wrong. I would love this remote if it wasn't for this problem. But a learning remote should be pretty simple to setup. But apparently this one took the "Little Bus to school". I feel better now. I think I'll walk over and turn the volume up.
