GENERAL INFORMATION
General Information
In 1999 Zenith will introduce a new B line of Projection
TVs. This new line will help carry Zenith into the new
millennium with its continued commitment to supply
innovative and high quality products to our customers. In
this manual we will discuss the new features and designs
incorporated in the new chassis line and newly designed
cabinets in an effort to enable our ASCs to offer better
service to our customers in the event that they require
service on their Zenith product.
The new B line ZP chassis family will be broken down
into service modules as follows: Power/Deflection P.W.B.,
Main Chassis (Signal P.W.B.), Signal Sub. P.W.B., VM P.W.B.
Jack Pack and SP Matrix (Audio) P.W.B. module. The new
Projection TV line will continue to be supported to the
modular level, which means that the repairs to these units
will be done by properly diagnosing a defective module
and replacing it. Since the Projection TV line will be
supported to the modular level there will be no need to
get prior approval from Tech Support for defective module
replacement.
Video Performance
Mechanical features include a Delta 78 lens system, single
piece Fresnel screen with special cut of the front and back
to add in distortion reduction when moving from one
viewing position to another. The screen also incorporates
vertical black strip matrixing which gives an increased
contrast ratio.
Electrical Features include a 2 line comb filter for processing
incoming signals to provide fine detail images, some higher
end products use the 3D Y/C comb filter. Auto skin tone
circuitry automatically maintains natural skin tones. Black
level enhancement, white level, and peak white level
compression circuitry maintains black/white contrast ratio
and peak luminance level for detail in both light and dark
video areas. All these features work together to provide a
resolution level of 800+ lines on the ZP90 series and 1000
lines on the ZP92 series.
Remote Access
When using the MBR for customer menus, it must be placed
in the TV mode (by pressing the TV button at the top). The
customer menu is a bar of ICONS at the top of the customer
menu display. By pressing the menu key you can select
which menu to use. Use of the Up/Down small arrows allows
the sub menu or feature item to be selected. To adjust or
change a feature selection you use the Left/Right small
arrows. Pressing the enter key usually allows you to exit
the customer menu.
