Important notes about your LCD TV
The following symptoms are technical limitations of LCD
Display technology and are not an indication of malfunction;
therefore, Toshiba is not responsible for perceived defects
resulting from these symptoms.
1) An after image (ghost) may appear on the screen if a fi xed,
non-moving image is displayed for a long period of time.
The after image is not permanent and will disappear in a short
period of time.
2) The LCD panel contained in this TV is manufactured using an
extremely high level of precision technology; however, there may
be an occasional pixel (dot of light) that does not operate properly
(does not light, remains constantly lit, etc.). This is a structural
property of LCD technology, is not a sign of malfunction, and is
not covered under your warranty. Such pixels are not visible
when the picture is viewed from a normal viewing distance.
Note: Interactive video games that involve shooting a "gun" type
of joystick at an on-screen target may not work on this TV.
Notes on handling
• • Do not subject the LCD panel to physical shock, such as dropping
it. It may cause unit damage and malfunction.
• • When shipping the unit, the original shipping carton and packing
materials come in handy. For fully protection, repack the unit as it
was originally packed at the factory.
• • Do not use volatile liquids, such as insecticide, near the unit.
Do not leave rubber or plastic products in contact with the unit for
prolonged periods of time.
Doing so will leave marks on the fi nish.
• • The top and rear panels of the unit may become warm after a long
period of use. This is not a malfunction.
• • When the unit is not in use, always remove the disc and turn off
the power.
Notes on locating the unit
• • When you place this unit near a TV, radio, or VCR, the playback
picture may become poor and the sound may be distorted. In this
case, place the unit away from the TV, radio, or VCR.
• • To avoid damage to this product, never place or store the
TV/DVD in direct sunlight; hot, humid areas; or areas subject to
excessive dust or vibration.
