If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on
the under the screen next to the on/off switch keeps flashing, then there may be an
internal fault on the set that needs to be reset.
To force the reset, try this:
- Unplug the set and wait a few seconds
- Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it
essentially shuts down the set. The flashing LED provides the indication that a
fault has been detected. Removing power to the set resets the monitoring
circuitry. When plugged back in, the circuitry again does a check of the
. If it finds that there truly is a problem, then the set is shut down and the
LED will again flash.
