Preface
This technical training guide will address
the disassembly and adjustments of the
Pioneer PDP-503CMX Plasma Display.
This guide was designed as a servicing aid
and is not intended to replace the service
manual. The student should have the
appropriate service manual on hand when
when using this guide. Data in the service
manual for this unit contains specific
information on safety, parts and adjustments.
Safety information
Important safety data for this Pioneer model
is contained in the service manual. Before
returning the unit to the customer, complete
all product safety obligations and tests.
Technicians who bypass safety features or
fail to carry out safety checks may expose
themselves and others to possible injury,
and may be liable for any resulting damages.
For more information on electronic
circuits and block diagrams refer
to Service manual ARP3093
Lead in the solder used in this product
is a known reproductive toxicant which
may cause birth defects or other reproductive
harm. (California Health and Safety Code
Section 25249.5).
When servicing this or handling circuit
boards and other components which
contain solder, avoid unprotected skin
contact with the solder. Also, when
soldering do not inhale any smoke or
fumes produced.

DVI-D interface for PDA-5002
11
There are two types of DVI interface; DVI-D and DVD-I. PDA-5002 has DVI-D input. Which
means this terminal can only accept Digital RGB signal.
Also the cable must be DVI-D cable.
(Yellow square)
DVI-I cable can not be used for PDA-5002.

Deep Waffle Rib Structure: realises even higher light emission
13
efficiency
For the PDP-503, Pioneer’s further improved this technology
by making each individual cell deeper.
Deep Waffle Rib Structure
(Deep Encased Cell Structure)
The new cell structure has a greater light emission area, so this results in
even higher light emission efficiency—50% higher than our previous model .
(PDP-502)
PDP basic principles
14
The PDP screen is 2 glass panels with pixels sandwiched. The pixels consist of tiny
cells with electrodes on the top and bottom. Inert gas (Xenon+Neon) is trapped
between 2 glasses, separated by a gap of just 100-200 microns wide. UV light is
generated by discharging the gas using electrodes. Red, green and blue phosphors
absorb these UV discharges and reradiate the energy as visible light to produce the
colors that appear on the screen.
Sustain

Address

Pioneer Method
[B-C] Initialization discharge
(Reset) charges the electric at
+/- electrodes, activating
gas to extract electron
[F] Address discharge selects the cells
required for emission by clearing the
electric charge from unnecessary cells
with comparatively small voltage
[D] Sustaining discharge is made by a pulse of voltage on sustain electrodes. It
generates UV light, which makes phosphor radiate visible light emission.
[E] The electric at electrodes remains so that continuous pulses of AC voltage
can make another light-emitting discharge

•Linear shaped characteristics of brightness level against input signal of conventional PDP is
poor at gradation in low brightness range
•Allocating comparatively more steps in low range, Characteristics of 503 has a gamma curve
similar to analog CRT, which doesn’t require the artificial process for offsetting gamma curve
of input signal in video processing

Each field (1/60 sec) can have 12 steps. (in case of NTSC)
With using 2 neighboring fields, different grayscales are
assigned. By combining these 2 fields, grayscales inbetween can be generated. As a result of it, another 12
steps can be implemented to get 2 times as many
grayscales as that of 1 field.

Gradation Reproduction in Low Brightness Range
17
Pioneer’s CLEAR* driving technology has succeeded in eliminating
false contour of poor gradation areas. Details in shadow that were
previously obscured in conventional PDP can now be seen.
(*CLEAR: high-Contrast & Low Energy Address & Reduction of false contour
sequence. We alternatively call it “Continuous Emission Display Technology”)
Even with dark images, detailed patterns are faithfully reproduced.
Pioneer CLEAR drive
Conventional PDPs exhibit rough gradations in the low brightness
range, so image quality in dark areas is inferior. Pioneer’s gradation
slope is much smoother.

•Continuous light Emission of the needed number of pulse
•No random light emission = No more random gaps without emission

•Less Addressing power consumption: 1/3 vs 501
•No Dynamic False contour

Input 3 : YC using a "S" connector and audio RCA X 2.
Input 4 : Composite in and out using (BNC) connectors
and audio RCA X 2.
Input 5 : DVI-D (Digital Visual Interface-Digital Host Only)
Audio can be connected to the main stereo mini
Jack for inputs 1 and 2.
Slot detect signal when inserted Is sent to the main CPU
Located on the RGB board. This allows inputs 3, 4 and 5
To be used as well as enabling High Definition signals
From inputs 1 or 2.
Signals from the DVI connector are sent through a TMDS
Receiver (Time Minimized Differential Signaling) and on
To the RGB board as 8 bit 2 phase digital RGB.

RGB Block Signal Flow
28
Inputs 1 or 2 from the I/O assy if RGB go directly to IC4603 (RGB A/D converter), if the signals are
component they enter IC4402 and then converted to RGB and sent to IC4603. After A/D
conversion takes place from IC4603 the now Digital 8-bit RGB is sent onto IC5001 & IC5102 the
interlace to progressive and selector IC’s. After I/P conversion the signals are sent out from
IC5001 as 2 channel 8-bit RGB through a selector switch and onto IC5301 the Digital Video
Processor IC. IC5301 contains the video correction circuitry needed to process the RGB signal.
Brightness, contrast, white balance, video enhance, screen size and on-screen display are all
controlled by IC5301. The output from the Video Process IC is 10-bit 2 channel RBG and exits
this assembly and enters the Digital Video Board.
Inputs 3 or 4 from the video card after conversion to Y/CB/CR (inside the video card) follow the
exact same path as the component flow for inputs 1 or 2.
The DVI input (input 5) from the video card is already 8-bit 2 channel digital RGB and bypasses
the RGB decode, A/D converter and I/P converter. The DVI signals directly enter the Digital Video
processor (IC5301).
Sync paths for all inputs enter IC4803 (sync processor) through various inputs. After sync
separation is preformed and analog to digital converting the sync outputs (for inputs 1, 2, 3 or 4)
is sent to the I/P select chip IC5001. The output from the I/P select chip is sent to a selector
switch. This switch will allow the RBG & sync or the DVI & sync to be sent onto the Digital Video
Process IC.
Sync signals are also sent to the system control IC (IC5505) to determine input signal frequency.

Digital Video Assembly

The 2 phase 10 bit RGB signal, sync, data and clock lines input the
Digital Video Assembly from the RGB assembly. The signals pass
through the line buffer and into IC1301 and IC1410 (sub-field Data
Generators) where the address data is generated and sent out to the left
section and right section address connectors A-D.
X and Y drive sustain control is preformed by IC1703 and the panel
microcomputer IC1101. The panel microcomputer monitors the
horizontal and vertical drive signals to select the proper refresh rate. The
module microcomputer IC1207 controls the panel microcomputer via
logic lines sent through voltage logic level converters. IC1207 is
controlled by IC5505 the main microcomputer on the RGB board. IC1207
functions also include thermal sensor monitoring, dew detection, reset
control and is used not only to switch on the power supply but to also
switch off the power supply should one of the power down detect lines
activate.
