Troubleshooting

ISSUE
No image is displayed.
Nothing happens when switching the main switch on. Image is unstable.
The remote control does not work.
Auto on/off does not work or does not function properly. Cannot control the display remotely via RS-232.

RECOMMENDED SOLUTION Check whether the cable is completely plugged in. Check whether the main switch is in the ON position, and the
power cord is completely plugged in. Check whether the image source's resolution is set as the
supported format (refer to section "Input Mode", p.24). Check whether the cable is damaged or bent excessively. Unplug the power cord from the socket and plug it in again
after a few seconds to reset the Signage.
Note: Unplugging the power cord will not change the settings. Check whether the cable is completely plugged in. Check whether there are batteries in the remote control. Check the batteries for freshness, polarity, etc. Check whether the remote is in the operation range. Bright light may interfere with the remote control. Please
avoid using the remote control near special fluorescent lights
or neon lights. Check whether the TIMER setting in the menu is set to "OFF". Check whether the "Power On Time" and "Power Off Time"
settings are set correctly.
Check whether the RS-232 cable is connected properly.

If you are still having trouble with your DynaScan DS² Professional LCD, contact your dealer or DynaScan directly for more assistance.
