It is normal for the Green LED to blink while the HDTV is in the booting up process for 20-60 seconds.
If blinking continues for more than 60 seconds (and you are not doing a software update) unplug the AC cord from the wall power outlet. Wait for 60 seconds before reapplying power to the HDTV.
If HDTV still does not fully power on you can remove all connections to the HDTV (such as your Blu-ray or DVD players or set-top-boxes) and then unplug AC and try again.
Note that a slow blink means a timer is set or that your DLP®
is in the "cool-down" period.
