Remarks
Possible cause: Many VCRs and DVD players provide on-
screen menus at only half-resolution. These lower-resolution
graphics may appear to jitter up and down when the TV con-
verts them to high-definition graphics.
• Turn off video mute for the VCR.
• Begin playing the tape.
• Change the VCR input to the antenna input.
The PerfectColor™ color balance has been incorrectly set.
Reset the PerfectColor balance.
Upgrade a Category 1 (unmarked) HDMI cable to a Category 2
HDMI cable.
Normal TV operation. The TV does not correct distortion in the
picture from a computer because the correction process may
cause the edges of the image to be cut off.
Remarks
• Check if the MUTE button is on.
• The TV's "Listen to:" setting may be set to SAP.
• Check that the Speakers option is set to TV to hear sound from the
TV speakers.
• If using an A/V receiver, check that the Speakers option is set to AV
Receiver to hear sound from the A/V receiver speakers.
• Perform a System Reset.
• The TV's Listen to: setting may be set to SAP.
• If using stereo or A/V receiver speakers, check their input selec-
tion in the Inputs > AVR menu.
• If using stereo or A/V receiver, check that DIGITAL AUDIO OUT
and/or AVR AUDIO OUTPUT on TV's back panel is connected to
the A/V receiver.
• NetCommand® is set up incorrectly for the A/V receiver.
Remarks
Turn the TV off for at least 2 minutes. Turn it back on. If light is
still red, the lamp has failed. Replace it. See Appendix C for lamp
replacement information. For questions, please call Mitsubishi Con-
sumer relations at (800) 332-2119.
