I need cobination codig for AIWA MX-NH1100, to programing remot control

It sounds like you're looking for a replacement remote control for your Aiwa Stack MX-Z9300m. Unfortunately, since your stack is an old model, it might be difficult to find a new remote control for it.
Here are a few options you can consider:

1. Check with Aiwa directly. Contact Aiwa's customer service and inquire about the availability of a replacement remote control. They may still have some stock of the original remote, or they may be able to provide you with information on where you can purchase one.
2. Check with electronics repair shops. Some repair shops may have the original remote control, or they may be able to repair or replace the remote control you have.
3. Check online marketplaces. Check online marketplaces such as eBay or Amazon for used or refurbished remote controls for your Aiwa Stack MX-Z9300m. Keep in mind that buying a used remote control may not be guaranteed to work properly, so be sure to research the seller's ratings and reviews before making a purchase.
4. Invest in a Universal Remote Control. You can purchase a universal remote control that can be programmed to work with your Aiwa Stack MX-Z9300m. These types of remotes are widely available and can be found at many electronic stores or online.
5. Consult the user manual or the technical specifications of your Aiwa Stack MX-Z9300m. You might be able to find information about the remote control that was originally used with the stack. With this information, you may be able to find an appropriate replacement remote control.

It's important to keep in mind that some of these options may not be an exact match for your Aiwa Stack MX-Z9300m, and may not have all the functions of the original remote control.
It's also important to check the Aiwa Stack MX-Z9300m's warranty status and the manufacturer's instructions to ensure that the repair or replacement will not void the warranty.

Question edited for clarity.

You need one specially made for this type of unit. There are lots available for this model for $19.

Presuming that the IR codes for the 0~9 numbers are captured correctly, then problems like this are usually down to either insufficient time between key presses, which can be solved by adding a small macro delay to each key; or the device being controlled is receiving multiple IR streams either directly from the hand unit and the IR emitters, or there's a blaster in the cabinet that's bouncing IR in multiple paths.

Hello,

what's the name/make and model of the remote?

Without me knowing the type of universal remote, there is no way I can get the right code for your TV.

I look forward to your reply.

Bye for now.

Was the replacement remote identical to the original one; or, does it need to be programmed. Also, if your replaced your old remote because it was not working, it might be that the IR sensor on your TV is bad.

I'm afraid, if there's no such a button on satellite remote control, the only way is to replace your spoiled remote control with a new one on the electronic part's shop.

Use an Aiwa Hifi Remote Control...Turn on the L300 (without any DVD on the player). Wait until in the TV appears "No Disc" Open the tray and put a DVD from other region (not zone 1), don't close the tray!!!. On the remote control of the Aiwa press the "Clock" button, in some remote control you must do a button combination like "Shift+9" (Is the combination to see the clock, do the combination fast), and in other model of Aiwa remote control doesn't appear the clock button, you must try with the "random" button. If you do it right, in the corner of TV where "No Disc" appears it will say "adjust complete".
