Indicators
Symptom Remarks
1. LAMP indicator light is a constant red. 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 B for lamp
replacement information. For questions, please call Mitsubishi
Consumer relations at (800) 332-2119.

Picture
Symptom Remarks
4. You cannot view a picture when playing a
VHS tape.
Check your VCR’s owner’s guide for further troubleshooting.
5. VCR or DVD player’s on-screen menus jitter
up and down.
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.
6. When viewing a stopped VCR, white lines
are rolling on the screen.
• Turn off video mute for the VCR.
• Begin playing the tape.
• Change the VCR input to the antenna input.
7. A color program appears as a black and
white image, or the colors are dim, or the
screen is black.
The PerfectColor color balance has been incorrectly set. Reset
the PerfectColor balance.
8. Picture from an HDMI input is noisy (poor
quality).
Upgrade a Category 1 (unmarked) HDMI cable to a Category 2
HDMI cable.
9. The image from a computer appears dis-
torted when viewed on the TV.
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.
