How can i get the code for my tv

You should have bought a remote that was made for your television. They are $20 and called Facsimile Remotes. No programming and an exact copy of the original. Universal Remotes are so 1980 :>D

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!

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:

I bought the same TV yesterday and I've used code 1065 to program my sky remote, which worked fine. It's thanks to the answer relating to Mitsubishi and TiVo cos I used a Mitsubishi code!! Hope it works for you.
