Your HITACHI Television incorporates advanced power surge protection technology designed to protect against
component or circuit damage due to external or internal voltage power surges.
TROUBLESHOOTING:
42
Note: A Power Surge can also relate to Power Interruptions or momentary black outs, most often noticed when
the lights dim or blink in the home. Due to the incorporation of sophisticated electronics, a rapid on/off of the AC
power can cause internal communication glitches when can make the Television appear to have “locked up”.
IF YOUR TELEVISION SHOULD APPEAR TO HAVE A LOSS OF POWER, PLEASE FOLLOW THIS PROCEDURE:
1. Press the POWER SWITCH (ON/OFF SWITCH) once.
2. If there is still no power, wait 30 seconds and press the POWER SWITCH again.
3. If there is still no power, unplug the power cord from the wall.
Wait 30 seconds and plug the power cord back in.
Press the POWER SWITCH again.
This protective technology should provide for years of lasting entertainment from your HITACHI Television.
