• Your TV uses a projection lamp as its light source. It is 

time to replace the lamp with a new one (not supplied) 
when:
– the lamp indicator on the front blinks in red,
– screen images become dark,
– no image appears on the display after prolonged use.

• In rare instances, the bulb may pop inside the lamp unit, 

but the lamp unit is designed to contain all of broken glass 
pieces inside the lamp unit. (See “Replacing the lamp” on 
page 47.)

• When the lamp eventually burns out, you may hear a 

noticeable pop sound. This is normal and is inherent in this 
type of lamp.

• The projection lamp contains mercury and should be 

disposed of properly. Consult your local authorities 
regarding safe disposal. If the lamp is broken during use, 
a small amount of mercury may be released. In this 
situation, move away from the product and ventilate the 
area. In case of accidental contact or inhalation, or if you 
feel unwell, consult a physician promptly.

This TV uses a cooling fan. You may hear some fan noise 
(depending on the placement of the TV), which may be more 
noticeable during the night, or when ambient noise is 
particularly low.
