Sony KDS-50A2020 Operating Instructions - Page 10

Getting Started 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 To replace the lamp, see page 51. 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). ✍ 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. 10
