Sony KF-E42A10 - Manual (Page 11)

Projection Lamp
Your TV uses a projection lamp as its light source. As
with any lamp, it has lifespan and needs to be replaced
when the lamp indicator flashes or the screen becomes
darker.
Notes
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-2400 replacement
lamp (not supplied). How to replace the lamp, see page 48.
Warning
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.
