After the POWER button is pressed, the image may flicker before the lamp becomes stable. This is not a product malfunction.

When this projector is connected with an HDMI device or DVI device supporting HDCP, such as a DVD player, image is not displayed correctly at the time of switching the input source on rare occasions. In such cases, switch to other input source and then switch back to the HDMI or DVI input source.

Sometimes flicker may appear on the screen when a component video signal is input. In such cases, adjust FINE SYNC. in the SIGNAL menu.
