for a long period of time, there may be some image

eliminate the image retention.

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 Indicator flashes 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
(one 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 lamp is replaced, please set the Lamp
Replacement option in the General
settings (see page 43).
"How to Replace the Lamp", see page 44.

your TV is in use. To avoid eye discomfort or ir_iury,
