WARNING
THE COMPONENTS IDENTIFIED WITH THE MARK ON THE SCHEMATIC DIAGRAM AND IN THE PARTS LIST ARE CRITICAL FOR SAFETY.
PLEASE REPLACE ONLY WITH THE COMPONENTS SPECIFIED ON THE SCHEMATIC
DIAGRAM AND IN THE PARTS LIST. IF YOU USE PARTS NOT SPECIFIED, IT MAY RESULT IN A FIRE AND AN
ELECTRICAL SHOCK.

SAFETY CHECK-OUT
After correcting the original problem, perform the following
safety check before return the product to the customer.
1. Check the area of your repair for unsoldered or poorly
soldered connections. Check the entire board surface
for solder splasher and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.
4. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer
and recommend their replacement.
5. Check the B + voltage to see it is at the values
specified.
6. Make leakage - current measurements to determine
that exposed parts are acceptably insulated from the
supply circuit before returning the product to the
customer.

1-2. Explanation of Terms

Deactivated batteries: Leaving an Ni-MH battery unused in storage for a long period may cause a rise in the level of
substances thatinhibit current flow inside the battery and result in a dormant battery. A battery in this state is referred to asdeactivated. Because current flow is inhibited in a deactivated Ni-MH battery, the battery•fs original level of performance cannotbe achieved.
DPOF: Digital Print Order Format
DPOF is a format used for recording information on a storage media (image memory card, etc.) that allows you tospecify which of the frames shot using a digital camera are to be printed and how many prints are made of eachimage.
EV: A number denotes Exposure Value. The EV is determined by the brightness of the subject
and sensitivity (speed)of the film or CCD. The number is larger for bright subjects and smaller for dark subjects. As the brightness of thesubject changes, a digital camera main­tains the amount of light hitting the CCD at a constant level by adjusting theaperture and shutter speed. When the amount of light striking the CCD doubles, the EV increases by 1. Likewise, when the light is halved, theEV decreases by 1.
Frame rate (fps): The frame rate refers to the number of images (frames) that are photographed or played back
per second. Forexample, when 15 frames are continuously photographed in a 1-second interval, the frame rate is expressed as 15 fps. For reference, TV images are displayed at 30 fps (NTSC).
JPEG: Joint Photographic Experts Group
A file format used for compressing and saving color images. The higher the compression rate, the greater the lossof quality in the decompressed (restored) image.
Memory effect: If an Ni-MH battery is repeatedly charged without first being fully discharged, its performance
may drop below itsoriginal level. This is referred to as the “memory effect”.
Motion JPEG: A type of AVI (Audio Video Interleave) file format that handles images and sound as a single
file. Images in the fileare recorded in JPEG format. Motion JPEG can be played back by QuickTime 3.0 or later.
PC Card: A generic term for cards that meet the PC Card Standard.
PC Card Standard: A standard for PC cards determined by the PCMCIA.
PCMCIA: Personal Computer Memory Card International Association (US).
WAVE: A standard format used on Windows systems for saving audio data. WAVE files have the
“WAV” file extension andthe data can be saved in either compressed or uncompressed format. Uncompressed recording is used on thiscamera. WAVE files can be played back on a personal computer using the following software: Windows:MediaPlayer Macintosh:QuickTime Player
* QuickTime 3.0 or later
White Balance: Whatever the kind of the light, the human eye adapts to it so that a white object still looks
white. On the other hand,devices such as digital cameras see a white subject as white by first adjusting the color balance to suit the color ofthe ambient light around the subject. This adjustment is called matching the white balance.
Exif Print: Exif Print Format is a newly revised digital camera file format that contains a variety of shoot-
ing information foroptimal printing.

3-3-2. MAIN Board Block Functions

Explanation of each block
CCD block / CAM block
Analog video signals output from the CCD Equipped with a 1/2.5-inch square-pixel interline CCD (total pixels 4.23 million
pixels) (U400)) undergo pseudo-color correction processing, adaptive interpolation processing, amplification (AGC) and signal mixing. Then the analog video signal is converted to 12bit digital signal, and sent to the DSP system.
Motor block
The DSP (M-2a/Spec 1.2E), which receives the command do signal from each operation system, control the motor drive
IC (TB6557FLG U200), and control the motor of AF/Shutter/Zoom/Iris.
Signal Process block
Input data from CCD
The 12bit digital image data sent from the CCD/CAM block is sent to DSP of camera (inside the DRAM (16 M byte)), which equals to 1 frame (2304 pix x 1728pix) is temporarily stored. At the same time, the image data sent to DSP is calculated in [Auto calculation block], to obtain the correct AE/AWB/AF. The data is sent to and temporarily stored in SDRAM.
Recording onto an XD-Picture card
The data temporarily stored in the SDRAM U102 (K4S281633F-BN75T00 is sent to the internal [Signal process block] in each line of DSP to undergo unpack process “32bit -> 10bit conversion”, “Digital clamp, γ correction, R/G/B each 10bit
->R/G/B each 8bit conversion pre-processing” -> “each 8bit digital R/G/B signal -> Y: Cb: Cr=4: 2: 2 YC processing”. The image data of Y/Cb/Cr each 8bit is sent to the inside buffer — SDRAM. [Inside buffer—SDRAM] change “each Y/Cb/ Cr signal of 8bit into the easily changed DCT pattern”. By the DSP [JPEG calculation compression] -> [Media controller] ­>SDRAM, and last stored in the XD-Picture card.
Playing back image data from an XD-Picture card
The compressed 8bit image data from the XD-Picture card is sent to it “SDRAM” -> DSP “MEDIA control section” -> [DMAUNIT] -> [Inside DRAM (16Mbyte)] -> [Media controller] -> [JPEG calculation block] -> [Signal process block]. The imaging system adjustment data is stored by Flash ROM.
LCD unit
The digital signal from DSP system is sent to the drive IC of LCD unit, through the process block of LCD FPC to undergo
LCD drive and LCD panel adjustment control.
DCDC BLOCK
The power supply circuits on the DCIC (U300), IC (U302), and IC (RT9178 U902) generate power supplies to following
blocks. 3V3M [DSP (U100), AD9925 (U901), FLASH ROM (U101), SDRAM (102)], STROBE IC (U801), MOTOR Drv.
