Overview - Zenith Presentation Series Service Manual

2K6
The CS series chassis will be used on the E-Line Commer-
cial Products. The Presentation Series PC-to-TV monitor
receivers were designed for educational and business
applications. This manual covers 27, 32, and 36 inch
screen sizes. The concept of this chassis is to make one
main board for all models and one power supply board
for all models in a particular screen size. Additional plug
in boards with jack packs may be added to the chassis
to accommodate the different features.
The CS series chassis features 11 IC's and 3 peripheral
devices for all signal, sync and sweep processing. The
ICX2200 handles the Base Band signal processing, the
RGB processing, and video switching for 4 systems (HV
sync signal processing included).

ICX2201 integrates the luminance signal processing,
Chroma signal processing, and the sync signal. The
ICX2600 was developed for various types of direction
compensation for point scan/multi scan TVs. The IC1400
includes functions such as stereo modulation, SAP (Sepa-
rate Audio Program), dBx noise reduction, and sound
processing. The IC2900 is an A/V switch which deter-
mines which auxiliary video and audio signals will be
processed by the video processor, also it can switch the
IF video signal. IC6000 is the main microprocessor and
IC6001 is the main memory.
All CS models are module level repair only. The table be-
low contains basic information on the Presentation Se-
ries. For more datails please see the Interconnect Dia-
gram in this Manual (section 5).
