Screen To minimize reflection, the screen surface has a special coating.
Inappropriate cleaning methods could damage the screen surface. Special
care is required.
Cleaning the Screen Surface
Dust and dirt on the screen can affect the picture quality. To dust off the
screen use a soft cloth. Be sure to follow the cleaning instruction on page 6
for stubborn stains and dirt.
Temporary Image Retention
When high contrast non-moving images such as station logos and channel
numbers are displayed for a long period of time, there may be some image
retention on the screen. This is only a temporary condition. Turning off the
power for a while or letting the TV run on another channel will eliminate the
retained image.
Projection Lamp Your TV uses a projection lamp as its light source. As with any lamp, it has a
lifespan and needs to be replaced when the LAMP LED blinks or the screen
becomes darker. Your TV also has a function to display a message
“Projection lamp is nearing end of life. Please replace the lamp.” to let you
know that the lamp has reached its expected lifespan. Note the following:
❑ After turning on your TV, it may take a while (1 minute or less) before
the picture appears.
❑ When the projection lamp wears out, the screen goes dark. Replace the
lamp with a new Sony XL-5200 replacement lamp (not supplied).
❑ After the lamp is replaced, set the Lamp Replacement option in the
Setup settings (see page 47).
To replace the lamp, see
page 51.
✍
Until you set the Lamp Replacement option, a message announcing
that the lamp is at the end of its life will appear every time you turn on
your TV.
✍
The light emitted from the lamp is quite bright when your TV is in use.
To avoid eye discomfort or injury, do not look into the light housing when
the power is on.
