5.6 Cooling system:
DVR5610 is a projection product which using UHP(ultra high pr essure) lamp as light source, most of heat is gen erated
from the UHP lamp, this feature leads to following thermal consideration.
In DVR5610, forced convection is designed as the main cooling mechanism, fans are employeed as active cooling devices to
circulate flow. Regarding to flow path scheme, fresh air will be sucked into system naturally and then cool the power module,
DMD, electronics board and then lamp, hot air behind lamp wake will be ventilated by an axial fan and be guideded by an
air channel then exhaust to outside ambient. This thermal system will provide about 15 CFM to circulate heat and keep low
temperature inside DVR5610. For the most important component,DMD, a high efficiency heat sink is designed to conduct
heat from DMD and then exchange heat with air that provided by a blower. This cooling design is applied to preven t DMD
damage from high temperature and make sure the lifetime of DMD.
5.7 Acoustic noise:
Acoustic noise measurements shall be conducted in accordance with ECMA 74 (5th edition).
The Equipment Under Test (EUT) is placed on a standard test table 0.5 m high, microphones centered on each face
of the EUT at a distance of 1.0 m from the EUT, 1.0 m above the floor. The free-field microphone shall point at the
EUT. The energy average A-weighted sound pressure level is reported. The EUT is placed on the floor fo r the sound
power test.

The I/P board PCBA contains circuitry that manages the major functions of the RPTV, including video ,
computer signal , deinterlacing,DCDi,PIP , HDCP and keypad IR signal processing.
The 8052 microprocessor
A 8052 CPU controls the projector system functions. The processor operates on 5.0 VDC power at a clock
frequency of 24.0 MHz.
The CPU reads and writes to all of the system peripherals to control system functions through it s 8-bit
2
data bus or two-wire I
C bus. The CPU connects directly to the Flash ROM,EEPROM VDu, deinterlace, tuner ,scaler, DMD…..
to check status, change modes and initialize the devices. The CPU also provides the ability to draw menus. It accomplishes this
by writing data directly to external OSD IC
The video decoder
The video decoder on the controller ECA includes composite video , S-video and Ycbcr signal processing.
The video decoder section does the actual selection of which video input to use for display. The I/O section
transmits the signals to the TV decoder section CPU VPC 32300 at all ti mes. Both inputs are hard-wire terminated
5Ω
. ESD protection is provided for both video inputs to protect the input st ages from externally produced discharges.

The signal from either source is sent through a decoder and on to the digital video bus.

RGB input from the VGA connector
From the VGA input, a differential RGB signal goes to the input ADC (MST 9883). This chip looks at
the vertical, horizontal. From there, the signal is converted to a 24 b it digital signal and sent to Scaler chip via
the digital bus.
The VGA connector also accepts differential inputs for direct processing. A software lookup table is used to
determine what type of signal is present. The input ADC sets up a phase lock loop and locks onto the
frequency.
Video processing
From the digital video bus, the signal next goes to the frame memory in the Scaler IC (gm6015).
Scaler manages the frame buffer to perform frame rate conversion. The frame memory is
asynchronous, meaning the input rate is different than the output rate. From this po int on the vertical and
horizontal frequencies will not change. The frame memory accepts information a page at a time.
When one page is displayed, another page is already in the frame buffer.
In the DVR5610, which has a native 1280 X 720 resolution, video inputs of 1280 X 720 and lower are
converted by the frame buffer to 75 Hz frame rate. The converted frames are then passed to the Scaler IC
for resizing up to 1280 X 720. The DVR5610 does not resize images larger than 1280 X 720.
In the DVR5610 Zoom model, Higher resolution is first resized down t o 1280 X 720 by dropping
lines and pixels, then converted by the frame buffer to 75 Hz frame rate, and finally passed to Scaler as
1280 X720 at 75 Hz. Video inputs of resolutions lower than 800 x 600 are converted by the frame buffer to
75 Hz frame rate and passed to the Scaler for resizing up to 1280 X720
The Scaler also provides the following support functions:
◆
Dual digital video inputs for MAIN and PIP display
◆ Dual bi- level / tri-level sync separators
◆ ”pixel-based” motion adaptive de-interlacing
◆
2:2/3:2 inverse pull-down film processing
◆
arbitrary shrink/zoom scaling on both MAIN and PIP channels
◆ ”3D” noise reduction filter
◆ Color space conversion
◆
Color controls
◆ Video look up table(VLUT) and multi-image PIP display
The Scaler provides high-quality resizing of VGA, SVGA, NTSC, PAL and SECAM inp uts up to the 1280 X720

that are passed through the LVDS to the DMD Driver Circuit .

Power supply PCBA(Refer to picture 2)
The power supply provides DC electrical power to all the electrical components in the rear projection television . DVR-5610
also contains a ballast that provides high voltage 380V necessary to strike the lamp when the rear projection television is
powered up. The attached fan draws cooling air through the power supply, as well as through the rest of the rear projection
television.

Short circuit protection
All voltage outputs shall have short circuit protection. Only 5Vs output shall be auto recovery after the short condition
removed.
Over voltage protection
All voltage outputs shall have over voltage protection, besides –20V( 6.24V for 5.1V, 5Vs outputs, 14.9V for 12V, 12Vs
outputs, 9.06V for 8V output, 25V for 20V output, 415V for 380V output )
Under voltage protection
All voltage outputs shall have under voltage protection, besides +/-20V and 380V outputs( 4.12V for 5.1V, 5Vs outputs,
9.7V for 12V, 12Vs outputs, 6.92V for 8V output )
Over temperature protection
There are 2 components TH200 on and TH201 that can sense the temperature on the heat sink HS200 and HS201. When an
abnormal condition is happened to make the temperature on HS200 or HS201 be more than 105’C, then TH200 or TH201
will be open to shutdown

Keypad ECA & IR PCBA(Refer to picture 4)
The keypad provides the user access to all of the controllable functions on the projector. It receives keypad
signals from the keypad attached to the top case, and then processes them before passing the signals to the
main board for command processing. also contains an IR receiver that collects and
processes the IR signal, which is then passed to the I/P board ECA.

Operating system
Flash EEPROM device
The projector stores its start-up and operating software code in a flash EEPROM device located on the main board
ECA. The flash EEPROM contains the following types of code:
System code
◆
The system code contains instructions required for system initialization and operation. As the
projector initializes, the system code reads and verifies the integrity of other data stored in the EEPROM,
such as lamp timer data and user-entered menu settings.
