Troubleshooting
Troubles sometimes are caused by simple “faults” that you can correct without the help of a service technician. If you
experience any difficulty with your TV, check a few basic remedies before calling your service technician.
TV will not turn on
• Check to make sure it is plugged in.
• Check the wall receptacle (or extension cord) to make sure it is “live” by plugging in something else.
• Maybe batteries in remote control are “dead.”
• Maybe remote control is not aimed at remote sensor.
• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by
selecting the
Front Panel Block in the Parental Controls menu and choosing Unblocked .
Controls don’t work
• If using remote control, make sure remote is in TV mode by first pressing TV button.
• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by
selecting the
Front Panel Block in the Parental Controls menu and choosing Unblock .
• Try unplugging set for two minutes and then plug it back in and turn it on again.
Problems with remote
• Maybe something is between the remote and the remote sensor.
• Maybe the remote is not aimed directly at the component (TV or VCR) you are trying to control.
• Maybe remote is not in TV Mode. Press the TV button so remote will control TV.
• Maybe batteries in remote are weak, dead or installed incorrectly. Try replacing batteries. (Note, if you remove the
batteries, you may have to reprogram the remote to control other components.)
• Remove batteries and hold number 1 for at least 60 seconds to drain the microprocessor inside the remote. Release
number 1, replace the batteries, and (if necessary) reprogram the remote.
Turns off while playing
• Scheduled Off function may have been activated.
• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then turn on
again. If this happens frequently, the voltage in your house may be abnormally high or low.
TV Turns on unexpectedly
• Scheduled On may have been activated.
Blank screen
• Maybe the component connected to the input jacks is not turned on.
• Try another channel.
• Press RESET, in case the picture controls are set too low.
No sound, picture okay
• Maybe sound is muted. Try pressing volume up button to restore sound.
• Maybe speakers are turned off. Check the Audio Output and Speakers control panel in the Audio menu.
• If using an S-Video component, remember to also connect the component’s L and R AUDIO OUT jacks to the TV’s L and
R INPUT jacks.
