ok look at the picture, i have to use A for let the pc recognize the stick, and i try everytime A and B when it's in the tv. i use usb 3.0 or 2.0 or an usb charger connected to the power supply, an ipad 2 one. i don't know wich one i'ts the correct one for the tv, i think B since A have DC written on the plastic, and just to understand better, should i first insert the tvstick in the tv, and than power it, or should i first power it and than plug in in the tv? and how many time should i wait usually to see something on the screen? thanks and sorry for the long post

Where you get the power from when using the stick on TV?
From a Power Supply or the TV's USB Ports.

A is for power supply, b is for flashing. And try different charger, hdmi cable, and different tv.
