I need the code list - RCA Universal Remote 3 Device Remote Control

Never worked on one, but I found this. Seems a known issue.

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.

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:

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.]]
