F9080 - Changing "Local Set"

[Patricko]

Hello there!

I just bought a new Samsung F9080 in Austria, the 55" size.
But I will be using it in Poland so I need to change few things in it, and TV doesn't let me to.

I want to change "Local Set" in service menu, because I couldn't get channels on DVB-T.
Default Local Set in service menu is "EU_GER" and I think that's the problem.
In main menu there are only 3 regions, which is: Austria, Germany and Switzerland.

I was trying the method with connecting IR Blaster to PC/Phone/etc. and running those WAV files, but nothing works for me.
I'm putting this little black box from Blaster near right down corner of TV, and of course I'm in service menu all the time.
But whatever sound I'm using...nothing happens. I tried many volume options, but I think that's not the problem here.

What I could be doing wrong?
