DTM 7.4 Troubleshooting Video

Video
• Confirm that the connection between the output jack on the connected device and the input jack on this unit is correct.
• Make sure that none of the connecting cables are bent, twisted, or damaged.
• When the TV image is blurry or unclear, the power cord or connection cables of the unit may have interfered. In such a case, keep distance
between TV antenna cable and cables of the unit.
• Check the switching of the input screen on the monitor side such as a TV.
Check the following if the problem persists after you have confirmed the above.
No image appears
• Change the input selector on this unit to the position of the jack to which the player is connected.
No image from a device connected to HDMI IN jack
• To display video from the connected player on the TV while the unit is in standby, you need to enable "2. Control" - "HDMI Standby Through" on the Setup menu.
• Check if "Resolution Error" is displayed on the main unit display when video input via HDMI IN jack is not displayed. In this case, the TV does not support the resolution of the video input from the player. Change the setting on the player.
• Normal operation with an HDMI-DVI adapter is not guaranteed. In addition, video signals output from a PC are not guaranteed.
• Try switching off the Deep Color function. To turn off the Deep Color function, simultaneously press the Zone 2 Off and Enter buttons on the
main unit. While holding down Zone 2 Off, press Enter repeatedly until "Deep Color: Off" appears on the display. To reactivate the Deep Color
function, repeat the above described step until "Deep Color: On" is appeared on the display.
