• The power won’t turn on.
- Check if the power cord is correctly plugged into the power outlet.
- When operating in below zero temperature, the enclosure may not work for up to one hour to raise the internal
temperature of the enclosure.
- For models with a circuit breaker, check whether the circuit breaker has been connected properly. The switch of the
circuit breaker must be set to on (red).
- Try turning the power on after disconnecting the AC adapter and cleaning the contacting port.
• The ‘Unknown Product’ message appears when the product is connected.

Issues Related to Screen (Video)
• A message saying ‘No signal’ or ‘Invalid Format’ appears.
- The signal cable is not connected between the PC and the product, or the cable connection status is unstable.
Check the signal cable.
- Access the input menu to check the input signal.
- The signal from the PC (Graphics card) is out of the vertical or horizontal frequency range of the product. Adjust
the frequency range by referring to the specifications in this manual.
• The position of the screen is incorrect.
- Check if the graphics card resolution and frequency are supported by the product. If the frequency exceeds the
supported range, use PC settings to set the resolution to the recommended value.
- D-Sub analog signal - Press the
button in the remote control to automatically select the optimal screen
status that fits into the current mode. If the adjustment is not satisfactory, adjust the display settings manually in
the OSD menu.
• The screen is displayed abnormally.
- Connect the signal cable that matches with the source input signal.
- Condensation may appear on the screen. It will disappear in a certain period of time after the product is powered
on.
- The condensation formed inside the product is a natural phenomenon and is not covered under warranty. (IPX6 is a
standard to protect the product from 100L of water per minute and not from infiltration of moisture in the air into
the set.)
29
• Images are flickering or fluttering on the screen.
- If you turn the monitor on when it is cold, the screen may flicker. This is normal.
- Make sure that the current resolution and frequency settings of the graphics card are supported by the monitor.
• Stripes appear in the background.
- D-Sub analog signal - Press the
button in the remote control to automatically select the optimal screen
status that fits into the current mode. If the adjustment is not satisfactory, adjust the display settings manually in
the OSD menu.
• Horizontal noise appears or the characters look blurred.
- D-Sub analog signal - Press the
button in the remote control to automatically select the optimal screen
status that fits into the current mode. If the adjustment is not satisfactory, adjust the display settings manually in
the OSD menu.
Issues Related to Screen (Color)
• Screen has poor color resolution (16 colors).
- Use PC settings to set the color to 24 bits (True Color) or above.
• Screen color is unstable or mono-colored.
- Check the connection status of the signal cable. Or, re-insert the PC graphics card.
• Black spots or bright spots appear on the screen.
- Some pixels (red, green, blue, black) are visible on the screen due to the unique characteristics of the display panel.
This is not a malfunction of the product.
• The screen’s brightness seems dark.
- Adjust brightness and contrast again.
- Backlight may need repair.
- If the internal temperature of the enclosure rises, the screen’s brightness may darken. Clean the heat exchanger or
filter in the enclosure periodically.
Issues Related to Sound
• There is no sound output.
- See if the audio cable is connected properly.
- Adjust the volume of the product or external device.
- See if the sound is set properly.

Image sticking
• After-image appears when the product is turned off.
- If you use a fixed image for a long time, the pixels may be damaged. Use the screen-saver function.
- When a dark image is displayed on the screen after an image with high contrast (black and white or gray), this may
cause image sticking. This is normal for display products.
• When the LCD panel displays a static image for an extended period of time, it can cause a voltage difference between
the electrodes that operate the liquid crystals. When the voltage difference between the electrodes builds up over
time, liquid crystals have a tendency to remain aligned in one direction. During this process, a previously displayed
image remains visible. This phenomenon is referred to as image sticking.
• Image sticking does not occur when using constantly changing images but may occur when using a fixed image for an
extended period of time. Therefore, it is recommended that you use the instructions below to decrease the likelihood
of image sticking occurring when using a fixed image. It is recommended that you change the screen at least once
every 12 hours at the very minimum; if done more frequently, the prevention of image sticking is more effective.
• Recommended operating conditions
1
Change the background and the character colors using the same time interval.
- When changing colors, using complementary colors helps to prevent image sticking.
A
A
ITO or MoTi Pixel Layer
2
Change the image using the same time interval.

• Vertical frequency: The product display functions by the screen image changing dozens of times every second like a
fluorescent lamp. The vertical frequency or refresh rate is the number of image displays per second. The unit is Hz.
• Horizontal frequency: The horizontal interval is the time taken to display one horizontal line. When 1 is divided by
the horizontal interval, the number of horizontal lines displayed every second can be tabulated as the horizontal
frequency. The unit is kHz.
The model and serial number of the product are located on
the back and on one side of the product. Record them below
in case you ever need service.
Temporary noise is normal when powering ON or OFF this
device.
