No need to shout....
Anyhow, here's how Samsung's TV model numbering works (NB, this is for current range - no doubt forthcoming ranges will be reassigned Klingon numerics or somesuch).
There's a series number, designed to denote the TV's place in the range, which runs from 4 up to 9.
Examples from Samsung website here.
Confusingly for you/us, that series number isn't at the beginning, but in the middle of the model number - in this case the first '6' in that PS50A
656 model number.
Several ranges include both LCD and plasma models. These are denoted by LE and PS prefixes respectively - so, going back to your 'mystery' TV, we now know it's a 6-series plasma set.
Next up is the model size - so, the PS
50A656 is a 50in 6-series plasma.
Lord knows what the "A" stands for - possibly the first year of this new car-like numbering system (Samsung compares it to the BMW range)?
And it gets more confusing...
The last two digits are typically market or retailer-specific designations. So, you may find a '56' model in, say, Currys, and an '86' model in John Lewis.
There's more on your 'mystery' set on the
Samsung website here. Sadly we haven't reviewed it yet (the plasmas did come out later than the LCDs, so there's still time...)
