Points to be checked Is the power plug loosened or disconnected? Is the main power turned OFF? No picture with the power on. Is the video signal output from the connected component? Is the input signal selected properly? Is the video cable disconnected? No sound. Is the audio signal output from the connected component? Is the volume output set to minimum? Is the audio cable disconnected? Shaking picture. Is the monitor close to a device generating a strong magnetic field? Is the color system selected properly? Has the picture control setting (CONTRAST, BRIGHT, CHROMA or PHASE) been changed? Unnatural, irregularly colored, or distorted picture. Dark stripes appear at the top and bottom of the screen, picture vertically squeezed. The overall picture size is too small. Function buttons on the front panel do not function. The INPUT SELECT buttons do not function. Is the monitor close to a speaker, magnet or any other device generating a strong magnetic field? Is the aspect ratio set to 16:9? Measures (Remedy) Firmly insert the power plug. Turn the main power ON. (See page 6.) Set the connected component correctly. Select the required video signal input with the Input select button. (See page 7.) Connect the video signal cable firmly. (See pages 13 and 14.) Set the connected component correctly. Adjust the speaker volume with the VOLUME/ SELECT button. (See page 7.) Connect the audio signal cable firmly. (See pags 13 and 14.) Move the device away from the monitor until the picture stabilizes. Set COLOR SYSTEM in the <MENU> screen to AUTO. (See page 9.) Set each picture control to the standard setting. (See page 7.) Move the device away from the monitor and turn the monitor�s power off. Wait at least 30 minutes, then turn the power on again. Set ASPECT RATIO in the <MENU> screen to [4 : 3 (4 � 3)]. (See page 9.) When controlling externally, ASPECT RATIO should be set to [4 : 3 (4 � 3)]. (See page 15.)

No colors, wrong color, or dark picture.

The following are not malfunctions:
� When a bright still image (such as a white cloth) is displayed for a long period, it may appear to be colored. This is due to the structure of the cathode ray tube and will be deleted when another image is displayed. � You experience a mild electric shock when you touch the picture tube. This phenomenon is due to a normal buildup of static electricity on the CRT and is not harmful. � The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an abnormality appears on the screen as well. � If two or more monitors are operated next to each other, their images may shake or be distorted. This phenomenon is due to mutual interference; it is not a malfunction. Move the monitors away from each other until the interference disappears or turn the power off on any monitor that is not being used.
