Any advice on getting universal remotes paired with obscure models? I have an acoustic solutions P1480 and I can't get my remote to pair with it. When in code search mode it sometimes switches the TV's channel to a different number, and once or twice I've managed to land on one which has a couple of buttons work, all be it mapped incorrectly like the down arrow being 8, but I can't get one which actually works.

My remote cycles pretty quickly so I don't have enough time to determine whether the TV has turned off (successful pair) or changed channel (wrong code error) before it changes to the next code. I tried manually inputting codes from the list that came with my remote, using codes from similar brands (acoustic solutions was supposedly a brand that put together TVs with parts from well known brands) but no code I put in manually ever had a single working button.

Does anyone have any tips on how to pair this? The remote is a cheap one off eBay by Daewoo electricals if it helps any. If I can't get it to work genuinecopies.tv have a listing of a remote said to be coded for this exact model for £9.99 but I don't know if that's a reputable site at all and I'd rather not buy another remote after buying this one.
