I'm using the TSU-3000 pronto with a sony DVP-NS3100es. The codes do not work Reliably unless I hold down the button for about a second. I'm going to Try It again with the same model back at our office to see if it is defective unit or if that is how that model operates. Has anyone else encountered this problem with that model? If so does anyone know a way around it so that the buttons will respond from a quick tap? I tried raising the duration of the code in pronto edit but it didn't seem to do anything.

Thank you for any help.

Set the duration to .15 Works everytime for me.

Have you tried holding the button down for a second?

I would have no problem holding it down if this were in my house but you know how customers can be. Anything that they see as a problem gets blown up into a major issue.

I was just kidding since an answer had been provided. I agrree and would never tell a customer they needed to do that.

If that doesnt do it, check make sure the battery in the thing is good.

Whenever i have had similar problems to this on other devices, it's usually an IR sensitivity issue. That is to say that you may be getting a constant low level flood of IR into the device via emitters that saturates a sensitive IR reciever on the device that an extended push manages to get through but a quick pulse does not.

Another posibility may be that IR from other emitters is bouncing around inside the cupboard and interfering with the IR going directly to your DVD player(including IR from the back of it's own emitter bouncing off the cupboard door). If the DVD player is more sensitive to IR than the other devices it can affect only that device.

I would firstly shield the IR window on the DVD player completely so that no other IR can possibly get into it and if that doesn't work try reducing the amount of IR going into the device from it's own emitter as well as shielding it from other possible IR sources.
A layer of white electrical tape between the emitter and the IR window usually works well although i have had occasions where i have had to use up to 4 layers to get enough reduction for reliable use.

I have made the assumption that you are using IR repeating equipment and that your equipment is in a closed cupboard here.
If it isn't, lets have some more details of how the equipment is housed and what other equipment is involved in the control side of things. Also what kind of display device are you using?

I hope some of this helps.

Simon reminds me of an old DSS problem -- when a DSS was set up to record to a VCR, an emitter from the DSS receiver was placed on the VCR. This emitter put out some kind of IR garbage all of the time, so sometimes the VCR did not respond, or did not respond quickly, to its own remote. The solution for that was to move the emitter away from the VCR's sensor, lowering the level of the IR garbage going into the VCR.

As has already been asked, is there other IR there?

Also, does the DVD player's factory remote do this too? I assume it does not as you only mention a problem with the 3000, but things would be more clear if we knew that the factory remote did or did not have the same problem.

There is a modification for Sony codes...a thread somewhere on this site explains the procedure. Work's perfectly...for me...

Quick procedure:

Here is the Sony DVD "play" IR code for Command Mode 1:

0000 0066 0000 0015 0061 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030
0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018
0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018
0222

This code is broken down as follows:

0000 (Raw format marker)
0066 (Timing factor)
0000 (One-shot pair count)
0015 (Repeating pair count)
0061 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0222 (Repeating data)

We are now going to add a one-shot to this code by simply copying the entire block of repeat data and pasting it one time at end.

0000 0066 0000 0015 0061 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030
0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018
0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018
0222 0061 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0030 0018
0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018
0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0222

Lastly we need to change the one-shot count to match the repeat count.

0000 0066 0015 0015 0061 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030
0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018
0030 0018 0018 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018
0222 0061 0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0030 0018
0018 0018 0018 0018 0030 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018
0018 0018 0018 0030 0018 0018 0018 0018 0018 0030 0018 0018 0222

That's all there is to it. This modified code will now work on a short button press using the latest firmware. The .1 second delay action is no longer needed. :-) How bout that for a work around!

have you tried holding down the button on the Sony remote for a few seconds while learning them into the pronto? I have had this same issue with a few pieces of gear ( Screen Innovations screens for one ) and this fixed the problem.
