“High Temperature Warning”
message appears
❏ Make sure to remove dust from the ventilation slots on the rear and both sides of
the TV. In addition, make sure that there are no obstacles in front of the ventilation
slots. If the message still appears after the dust or obstacles are removed, the TV
may need servicing. Call your local Sony Service Center.
The TV does not turn on ❏ The TV cools down its projection lamp when the power is turned off. It takes up to
two minutes for the picture to come back after the TV is turned on again. Wait for
a while until the picture comes back.
Small bright or black dot in
picture
❏ It may be possible to see one or two pixels, which appear dark or bright when
viewing up close to the screen caused during the manufacturing of the display
device. This is not a defect with your TV and will not affect the overall picture
performance or reliability of your set. Please view the screen at the recommended
viewing distances.
Image left on the screen (image
retention)
❏ Turn off the TV for a while or let the TV run on another channel. Unlike plasma
TV and CRT TV, image retention on this TV is not permanent.
It is only a
temporary condition; see page 10.
White spot on the screen when
powered off
❏ If screen is exposed to direct sunlight or strong ambient light, part of the screen
may appear white even when TV is power off. This is due to the strong light
reflecting off the TV screen and reflections coming behind the screen. This is a
structural property of the projection TV and is not a defect. Position your TV
away from such light sources.
