I not remember well, but 1.07A i think, but the screen go on only whit white light, only not have image.
Finally i found a component smd 6 pin, sot26 marked whit PAB73, in 5.5v, but out only 1.63 (the same voltage in pin of flat lcd). i apply 3.3V whit power supply on the out of component, and the image go on. I desolder component and pin 1,2,5 and 6 are join in pcb. you know what componen can to be?
I search it in in turuta smd book 2012 version but not appear...

if you have only 3 pins in out and gnd (1256) just measure A and fit any 3v3 voltage regulator.
