did dotstar 72 led consume power even if all led are off ?

I notice a strange thing about the dotstar strip 50 cm 72 led: when I start a simple program from an arduino: turn on the 72 led for 1 second then turn off (put the color 0x000000). The strip heats a lot, more and more, while all leds are off! Is it normal ? After a minute I have to cut off the power.
(In reality, not all leds are off, the last led, then now the last but one, is always 100% white, it does not react to commands, i think it's broken, but I do not think one single led drains so much power.
My question is: does the strip consume electricity even when all leds are off?

Forget!! I fed this poor strip with 12V. No wonder it heats, and the last two leds have lost the north ... With 5V, there is no problem, no accidental overheating ..
It's even amazing that this dotstart still works after several tries with this voltage ...
