Generally speaking, a flashing white LED light on the devices means that the device has lost the network connection (ie. no longer connected to the network, or internet is unavailable). When flashing, you will usually see a "Not Connected" message in upper right of screen.
At other times, I have seen the light flash when undergoing an OS update (generally during the reboot process, when it temporarily disconnects from the network).
Thank you very much. It was flashing that time during night. I checked tv during the flashing and tv was working fine. And today in morning I noticed the white light was steady On. Again tv working fine. So who knows what the reason was for each. I was afraid the Stick was heating up. Don't want flames or trouble here, especially that it's always plugged in and I'm not always there. Thank you again.
