Palsonic 3490 remote code

[whozit2u]

I have a Palsonic 3490 (portable 34cm) and have connected a DVD player to it. Problem is I dont have the original remote and the tv doesnt have an AV button on it. I have tried a zillion different codes on my universal remote and currently have the majority of the buttons working - but you guessed it - the one I need doesnt work. current code is 220. I have contacted Palsonic but none of the codes they gave work either. :(
Can anyone help me with the right code or a solution to the problem?
