Thank you that's very helpful,
I have now spoken to my electrical contractor in Portugal, she says there are no voltage issues both countries are the same. She can install a digital box if necessary but is not sure about the firmware, please can you explain to a layman what this is?
Also do you know how I contact Samsung to check if the TV's I want to buy are Multistandard?
Colin do you still need help with this ?If not could you please consider rating the answer positively so I receive credit from the site thank youRegardsAnthony
