Troubleshooting
If the Projector seems to have a problem, first review this list of possible problems and solutions. Alternatively,
review the Troubleshooting Section in the e-Manual. If none of the troubleshooting tips apply, please visit
"www.samsung.com" and click Support or contact the Samsung service centre listed on the back cover of this
manual.
• To keep your Projector in optimum condition, upgrade to the latest software. Use the Update Now or Auto
update functions on the Projector's menu (
> Settings > Support > Software Update > Update Now or
Auto update).
The Projector won’t turn on.
• Make sure that the AC power cable is securely plugged in to the Projector and the wall outlet.
• Make sure that the wall outlet is working and the Remote control sensor at the front right of the Projector
is lit and glowing a solid red.
• Try pressing the Power button at the rear of the Projector to make sure that the problem is not with the
remote control. If the Projector turns on, refer to “The remote control does not work".
There is no picture/video/sound, or a distorted picture/video/sound from an external
device, or “Weak or No Signal” is displayed on the Projector, or you cannot find a channel.
• Make sure the connection to the device is correct and that all cables are fully inserted.
• Remove and reconnect all cables connected to the Projector and the external devices. Try new cables if
possible.
• Confirm that the correct input source has been selected ( > Source).
• Perform a Projector self diagnosis to determine if the problem is caused by the Projector or the device (
> Settings > Support > Device Care > Self Diagnosis > Picture Test or Sound Test).
• If the test results are normal, reboot the connected devices by unplugging each device's power cable and
then plugging it in again. If the issue persists, refer to the connection guide in the user manual of the
connected device.
• If you are not using a cable box or satellite box, and your Projector is receiving TV signals from an antenna
or a cable wall connector, run Auto Tuning to search for channels (
> Settings > Broadcasting > (Auto
Tuning Settings) > Auto Tuning).
– The Auto Tuning Settings may not appear depending on the model or geographical area.
– If you are using a cable box or satellite box, please refer to the cable box or satellite box manual.
The remote control does not work.
• Check if the Remote control sensor at the front right of the Projector blinks when you press the remote's
Power button. If it does not, replace the remote control's batteries.
• Make sure that the batteries are installed with their poles (+/–) in the correct direction.
• Try pointing the remote directly at the Projector from 1.5-1.8 m away.
• If your Projector came with a Samsung Smart Remote (Bluetooth Remote), make sure to pair the remote to
the Projector.
