That sounds good.
I think our 2 best bets are either to get the information from Samsung? That could be much harder than it sounds. Or as you said, maybe someone online will be able to take a photo or jot down the settings.
Not sure about going into a TV shop though, I could see that going horribly wrong.
Moogler, Thanks for getting us this far. I'll let you know how I get on.
Also a big thanks to The_Pickel. You have been a great help and I can't tell you how much I have appreciated your thoughts and comments. The TVs are almost back to normal. We have made significant progress using the NZ firmware supplied to us from Samsung. We installed it, change a couple of settings such as model type and country (thanks for those ideas) and now we don't have the check fan 1 error. We also can now view our digital channels. I think the model we selected "Pearl_P1" isn't the actual model though but I'm sure we are almost there. Hopefully to tidy things up all we need to do is find the correct settings.
