IC3001: Main CPU / VIDEO PROCESSOR.
Part Number: VCT7993P-FA-A1-H000 SHARP Code: RH-IXC354WJZZQ
The VCT 77VWP (VCT-Pro) family is dedicated to high-quality FPD and double-scan TV sets. The memory and program ROM are integrated in
the IC. Modular design and deep submicron technology allow the integration of audio, video, Teletext, OSD, and controller-related functionalities.
They cover the whole range of flat-panel display TVs. Each member of the IC family contains the entire audio, video, up-conversion processing for
4:3 and 16:9 50/60 Hz progressive or 100/120 Hz interlaced stereo TV sets plus the control/data interface for flat-panel displays. The integrated
microcontroller supports a powerful OSD and graphics generator with integrated Teletext acquisition.
The VCT 77vwP family provides a front-end video-processing unit with 4 CVBS-Y/C or component inputs for HDTV, EDTV and SDTV. A VBI slicer,
support of 2000 pages of Teletext, and a 3-D comb filter for PAL and NTSC (in certain versions) are also available. The front-end unit further allows
processing an SD and an HD source in parallel, thus enabling PiP and PaP functionality. Motion-adaptive de-interlacing, temporal noise reduction,
and film mode detection are based on a unified memory technology. Post-scaling in the display-processing block ensures the desired output format.
Display processing is supported by an 8-bit 8051-compatible controller. By means of powerful alpha blending, the graphics mixer composes the
output image from following image layers: the video layer, the OSD layer and the pixel graphics layer. The audio part consists of a multi-standard
sound IF demodulator and a base-band processor supporting all desired sound features in this range.
The VCT-Pro front-end video processing unit offers 16 analog video inputs (CVBS/Y/C, RGB/Y Cr Cb) as well as digital interfaces for SDTV and
HDTV. Latest 3D+ comb filter generation provides highest performance for PAL/NTSC signals.
A VBI slicer, supporting up to 2000 pages of Teletext completes the analog video front end. 3D-motion-adaptive de-interlacing, temporal noise re-
duction and film mode detection are based on a unified memory technology.

IC1301: DIGITAL AUDIO POWER AMPLIFIER
Part Number: YDA147-SZE2 SHARP Code: VHIYDA147SZ-1Y
This IC is a Stereo 20W (10W+10W) digital audio power amplifier. The IC is class D amplifier equipped with the function for the dynamic self-adjust-
ment of the output volume in proportion to the amplitude of the input signal. The company calls the function of automatic adjustment of the installed
output volume “DRC (dynamic range compression)”.

4. Service Mode
HOW TO ENTER TO SERVICE MODE
Press the “POWER” key on the set of running TV set to force off the power.
While holding down the “VOL (-)” and “INPUT” keys on the set at once, plug in the AC power cord to turn on the power.
The letter “K”, appears on the screen.
Next, hold down the “VOL (-)” and “P (-)” keys on the set at once. Multiple lines of character string appearing on the
screen indicate that the set is now in the adjustment Process mode. If you fail to enter the adjustment mode (the display
is the same as normal start-up), retry the procedure. (Another procedure)
To exit of Service Mode, after the adjustment is done, unplug the AC power cord to force off the power. (When the
power is turned off with the remote controller, once unplug the AC power cord and plug it in again. In this case, wait 10
seconds before plugging.)
