standards?? And do I demand a refund?

How long did you wait after switching it into standby? Our Panasonic
TVs only enter their very low power standby mode after a few minutes,
when there is an audible click from (presumably) a relay in the set.
Until then the power consumption is much higher.

I suggest you repeat your measurement after the TV has been in standby
for, say, at least ten minutes.
