I have a onn tv and my cable company is spectrum so what is code to program cable remote control for a onn tv?

Question edited for clarity.

No one buys Universal Remotes these days, they are so 1980! You buy a Facsimile Remote, an exact copy of the original like this one.

I would look the code up on the remote manufacturers web site list.

AVOL 4 digit codes:
2735 1820 3382 2051 2397 3118

AVOL 5 digit codes:
13118 13382 13479 12735 12051 12397 12278 11531

for every remote control device ever made since the beginning of remote control devices?

No problem, but next time, PLEASE give us some clues!

To program your Bose CineMate home theater system with the Spectrum remote, you will need to use the appropriate remote control codes. These rules vary depending on the model of your Spectrum remote and the specific model of Bose CineMate you have. Follow these detailed steps to program your Spectrum remote to control your Bose CineMate: Find the remote control code: First, you need to find the remote control code for your Bose CineMate system. Spectrum provides a list of remote control codes for devices on their website or in the remote control user manual. You can also try looking up specific codes online using the model number of your Spectrum remote and Bose CineMate. Turn on Bose CineMate: Ensure that your Bose CineMate system is turned on and in the proper mode for operation (e.g., TV or AUX mode). Enter programming mode: Press and hold the "Setup" button on your Spectrum remote until the LED indicator on the top of the remote turns on. Enter Code: Use the number buttons on the remote to enter the four-digit remote control code of your Bose CineMate. The LED indicator blinks to confirm the entered code. Test control: After entering the code, point the Spectrum remote at the Bose CineMate system and press various buttons (e.g., volume up/down, power) to see if it controls your Bose system. If it works, the program succeeds. Save the code: When the remote control works with your Bose CineMate, press the "Setup" button again to exit the programming mode. Now that the code is saved, your Spectrum remote should be able to control your Bose CineMate. Please note that not all remote control codes may work with all models of the Bose CineMate. If you can't find a working code, you can try the code search feature in your Spec

wharfdale TVs are rebadged by Argos, so I am unsure of the actual manufacturer, and therefore the control signal scheme that they use.
It might help if you gave the model number of the particular TV, as they could be using several different manufacturers in their range of televisions.
it is unlikely there will be a single code that covers the whole range of Wharfdale Tvs

I have had very good luck with this site:
