Health & Safety Code Section 25249.6 - Proposition 65
1. SAFETY PRECAUTIONS
NOTICE : Comply with all cautions and safety related notes
located on or inside the cabinet and on the chassis or
picture tube.
The following precautions should be observed :
1. Do not install, remove, or handle the picture tube in any manner
unless shatterproof goggles are worn.
People not so equipped should be kept away while picture tubes
are handled.
Keep picture tube away from the while handling.
2. When service is required, even though the HDTV PROJECTION
MONITOR an isolation transformer should be inserted between
power line and the set in safety before any service is performed.
3. When replacing a chassis in the set, all the protective devices
must be put back in place, such as barriers, nonmetallic knobs,
adjustment and compartment covershields, isolation resistorcapacitor, etc.
4. When service is required, observe the original lead dress. Extra
precaution should be taken to assure correct lead dress in the
high voltage circuitry area.
5. Always use the manufacture's replacement components.
Especially critical components as indicated on the circuit
diagram should not be replaced by other manufacture's.
Furthermore where a short circuit has occurred, replace those
components that indicate evidence of overheating.
6. Before returning a serviced set to the customer, the service
technician must thoroughly test the unit to be certain that it is
completely safe to operate without danger of electrical shock,
and be sure that no protective device built into the set by the
manufacture has become defective, or inadvertently defeated
during servicing.
Therefore, the following checks should be performed for the
continued protection of the customer and service technician.
Leakage Current Cold Check
With the AC plug removed from the 120V AC 60Hz source, place
a jumper across the two plug prongs. Turn the AC power switch
on. Using an insulation tester (DC 500V), connect one lead to the
jumpered AC plug and touch the other lead to each exposed metal
part (input/output terminals, screwheads, metal overlays, control
shafts, etc.), particularly any exposed metal part having a return
path to the chassis should have a minimum resistor reading of
0.3MΩ and a maximum resistor reading of 5MΩ. Any resistor
value below or above this range indicates an abnormality which
requires corrective action. Exposed metal parts not having a return
path to the chassis will indicate an open circuit.

AC Leakage Test
Leakage Current Hot Check
Plug the AC line cord directly into a 120V AC 60Hz outlet (do not
use an isolation transformer for this check). Turn the AC power
switch on.
Using a "Leakage Current Tester (Simpson Model 229 equivalent)",
measure for current from all exposed metal parts of the cabinet
(input/output terminals, screwheads, metal overlays, control shaft,
etc.), particularly any exposed metal part having a return path to
the chassis, to a known earth ground (water pipe, conduit, etc.).
Any current measured must not exceed 0.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED BEFORE
RETURNING THE SET TO THE CUSTOMER.
High Voltage
This set is provided with a X-ray protection for clearly indicating
that voltage has increased in excess of a predetermined value.
Comply with all notes described in this Service Manual regarding
this hold down circuit when servicing, so that this X-ray protection
may correctly be operated.
Serviceman Warning
In the status of the black picture (video muting is being applied)
when no signal is input, high voltage of this set during operation is
less than 30.5kV. In case any component having some relation to
the high voltage is replaced, confirm that the high voltage is lower
than 30.5kV in the status of the black picture when no signal is
input.
To measure H. V. use a high impedance H. V. meter.
Connect (–) to earth and (+) to the FBT anode cable connector.
(Refer to section "7.1.2 DISASSEMBLY".)
X-radiation
TUBE : The primary source of X-radiation in this set is the picture
tube.
For continued X-radiation protection, the replacement tube must be
the same type as the original, PIONEER approved type.
The picture tube (CRT Service Assy R, G, B) used in this set holds
complete guarantee against X-ray radiation when the X-ray is
sealed (next page ). Accordingly, when the current in flowing to the
picture tube (CRT Service Assy R, G, B), be sure to perform it by
putting the tube into X-ray sealed applied state. Avoid absolutely to
flow the current to the picture tube (CRT Service Assy R, G, B)
itself. Moreover, when the voltage of the high voltage circuit
becomes abnormally a little higher, the picture tube radiates X-rays.
Accordingly, when servicing the high voltage circuit be sure to
replace as an assy with the POWER SUPPLY Assy in the manner
in which has been adjusted to perform normal operation.
Many electrical and mechanical parts in PIONEER set have special
safety related characteristics. These are often not evident from
visual inspection nor the protection afforded by them necessarily
can be obtained by using replacement components rated for higher
voltage, wattage, etc. Replacement parts which have these special
safety characteristics are identified in this Service Manual.
Electrical components having such features are identified by
marking with a > on the schematics and on the parts list in this
Service Manual.
The use of a substitute replacement component which dose not
have the same safety characteristics as the PIONEER
recommended replacement one, shown in the parts list in this
Service Manual, may create shock, fire, X-radiation, or other
hazards.
Product Safety is continuously under review and new instructions
are issued from time to time. For the latest information, always
consult the current PIONEER Service Manual. A subscription to, or
additional copies of, PIONEER Service Manual may be obtained at
a nominal charge from PIONEER.

Progressive Scan/HDTV monitor
All SDTV and HDTV signals are converted to 1080i and displayed at
high resolution.
DVI (Digital Visual Interface) with Copy Protection
system
The combination of Digital Visual Interface (DVI) and High-bandwidth
Digital Content Protection (HDCP) is important for viewing copyprotected digital contents through SAT/CATV BOX or DVD player.
DIGITAL input terminal receives the signal in the form of digital
information. In this way, all signals coming into this interface have a
very high resolution and less noise compared to an analog interface.
Dual System Component Input for NTSC/
Progressive
Connection to a DVD player using the component output terminals
makes possible a high picture-quality display, superior to that of a SVIDEO terminal connection. This also handles high resolution
component input (1080i, 480p), which will function as an interface
for high-quality images in future.
Dual Tuner (Split Screen and CH Search screen
function)
Two TV tuners are provided, making it possible to split the screen
vertically in two areas in order to display moving images
simultaneously on each of them. In addition, the channel search
function makes it possible to check and perform other functions etc.,
on the program that you choose to run in the background, while
viewing the foreground program. This adds remarkable convenience
when you are concerned with viewing two programs.
Pioneer PureCinema III Format Converter
An advanced and exclusive I/P (Interlace/Progressive) third generation
format converter called “PureCinema III”, delivers a high-resolution
progressive picture (480p) or Interlaced picture(1080i). *This is USER
SELECTABLE
It reproduces film material in a very smooth and film-like image.
This is perfect technology for movie lovers.
Anti-Reflective Tinted Protection Panel
The accompanying protective panel is AR (Anti-Reflective) coated
and tinted.
This is not only to protect the screen, but to present a more natural
and high contrast image with less light reflection. This AR coating is
very durable against scratching.
Lens System for HDTV
The adoption of a specialized lens system for high-resolution HDTV
which faithfully reproduces HDTV 1080i signals allows for highly colorsaturated images to be displayed at high resolution. Also, by
incorporating an “achromatic coated” lens for the blue CRT, the
picture image is reproduced with less halo and appears sharp.
Reference Theater mode and PRO mode
<Reference Theater Mode>
This mode reproduce film material just like a real film image. By
cutting video enhancement circuits, the picture becomes more natural
and looks film-like.
<PRO Mode>
This mode offers pro level video adjustment to the user. You can go
into several areas such as: LTI (Luminance Transient Improvement),
Gamma, White Balance.
Fully Illuminated Remote Control Unit
A fully illuminated universal remote control is used that makes it
possible to operate other devices. Remote operations can thus be
performed easily even in dark rooms and similar environments.
Multi-Point Convergence System
Convergence of the red, green, blue guns* in the TV is critical to a
good picture. Thanks to new convergence system digital technology,
not only can the center of the screen be adjusted, so can an amazing
72 other points across the entire viewing area. This ensures color
accuracy throughout the screen. The adjustment is easily done from
the remote control. (*guns = cathode ray tubes)
Room Light Sensor (RLS)
When you select RLS “on” (LEVEL1, LEVEL2), in accordance with
the ambient light of your room, the TV automatically adjusts the
picture brightness to reduce eye strain.
Program Block (V-CHIP)
You can block selected programs based on the established rating
system for television programs and movies. The rating systems are
defined below:
<U.S.A. RATING SYSTEM>
The TV parental Guidelines are used to rate
<TV-Y>, <TV-Y7>, <TV-G>, <TV-PG>, <TV-14> and <TV-MA>.
The Motion Picture Association of America(MPAA) guidelines are used
to rate
movies: <G>, <PG>, <PG-13>, <R>, <NC-17>, <X> and <NR>.
<CANADIAN RATING SYSTEM>
The Canadian
television programming: <C>, <C8+>, <G>, <PG>, <14+> and <18+>.

Tuner, Video and “S” Input Block Explanation
(See Pages 17 and 18)
Main Picture (Tuner or Composite)
Input switch (IC2201) receives signals from the tuner, inputs 1 ~ 3 and the front
input (input F). Signals from the tuner or composite signals from inputs 1,2,3 or F
enter IC2201 and the user selected output for the main picture goes to IC2503.
IC2503 is a 3D Y/C separator for the main picture composite signals. After the
composite signals have been changed to 3D-Y/C signals they enter IC2803 and the
color demodulator inside this IC changes the signals to Y/CB/CR. IC2803 also
separates the horizontal and vertical sync. All signals at this point are sent onto the
progressive unit for I/P conversion. All signals entering the progressive unit are
converted to 480P at 31K or 1080I at 33K (user selectable). Signals entering the
progressive unit are converted to digital and resized for the user selected screen
mode and scan mode. The output signals from the progressive unit are converted
back to analog and the Y/CB/CR signals pass through switch IC4305 and go into the
sharpness and detail correction IC (IC4301) or bypass IC4301 through switch
IC4306 and enter IC4608. All picture, color correction and sync processing is done
inside IC4608. The output processed RGB signal from IC4608 is sent to the CRT
drive PCB’s.
Main Picture (“S”)
Inputs from the “S” connectors (inputs 1,2,3 and F) are user selected by IC2201 and
outputted to IC2503 as Y and C signals. Since these signals are already separated
IC2503 simply passes the signals through onto IC2803. From this point the signal
path is exactly the same as (Tuner or Composite).
Sub Picture (Tuner, Composite or “S”)
The sub picture path is used for the twin picture function and the multi picture
tuner scan feature. Any signal input into IC2201 can be used for the sub picture
output. The user selected sub picture output from IC2201 goes to IC2701 for Y/C
separation if the signal is Tuner or Composite. If the signal is of the “S” type it
simply is passed through IC2201 and enters IC2806 for color demodulation and
sync separation. The outputted Y/CB/CR and sync signals are then sent to the
progressive unit for twin picture or multi picture processing.
Page 27
Component Input Block Explanation
(See Pages 19 and 20)
Main Picture (Input 1 or 2 Component 480I 15K, 480P 31K and 720P
45K)
IC3901 is used as the input 1 and 2 main picture selector and if the input is 480I,
480P or 720P the user selected signals pass through IC3901 and enter IC2803. The
Y/CB/CR signals bypass the color demodulator and go directly to the progressive
unit. The sync signals are separated by IC3901 and pass through IC2803 and onto
the progressive unit for processing. 15K sync signals entering the progressive unit
are doubled, 31K pass though and 45K signals are converted to 31K and outputted
to IC4608 for final processing.
Sub Picture (Input 1 or 2 Component 480I or 480P)
Component inputs 1 or 2 can be used for the sub picture (twin picture) function as
long as the signals are 480I or 480P and full mode has not been selected. Note: 720P
cannot be used as a sub picture source. 720P defaults to full screen mode only.
IC3906 is the input user selector switch for the sub picture from component inputs 1
or 2. The selected Y/CB/CR signals along with the separated sync signals go to
IC2806. The Y/CB/CR and separate sync signals pass through IC2806 and go onto
the progressive unit for twin picture and sync processing.
Main Picture (1080I 33K and 480P Full-Mode)
IC3901 (the main picture component output selector) user selects input 1 or 2 and
outputs the Y/CB/CR signals in 1080I or 480P full-mode format and sends the
signals to IC4305 (the full component switch). From IC4305 the signal directly
enters IC4606 for picture, color and RGB processing. The separated 31k or 33K
sync signals from IC3901 also go directly to IC4606 after passing through switch
IC4610 for sync processing. 480P full-mode requires no size conversion from the I/P
converter inside the progressive unit.
Page 28
DVI & RGB Input Block Explanation
(See Pages 21 and 22)
Main Picture (Input 5 or 6 DVI 480P)
From the selector IC inside the DVI module the user selects input 5 or 6 and that
DVI-RGB signal and sync is sent to IC3901 to be converted to Y/CB/CR and
separate H and V sync. The outputs of IC3901 go directly to IC2803 but only pass
through this IC as they are already component signals and the sync has been
separated. From IC2803 the signals are sent to the progressive unit for size and sync
processing and onto IC4608 for final picture, color correction and sync processing.
Sub Picture (Input 5 or 6 DVI 480P)
Only one DVI input can be used to produce a sub picture (split screen effect) along
with one of the other inputs. If the user selects input 5 or 6, the selector IC inside the
DVI module sends that output to IC3906 for RGB to Y/CB/CR converting along
with sync separating of the H and V sync signals. At this point all signals pass
through IC2806 and onto the progressive unit for twin picture and sync processing.
Main Picture (1080I 33k and 480P 31K Full-Mode)
IC3901 (the main picture DVI output selector) selects input 5 or 6 and converts the
RGB signals into Y/CB/CR signals in 1080I or 480P full-mode format and sends the
signals to IC4305 (the full component switch). From IC4305 the signal directly
enters IC4606 for picture, color and RGB processing. The separated 31k or 33K
sync signals from IC3901 also go directly to IC4606 after passing through switch
IC4610 for sync processing. 480P full-mode requires no size conversion from the I/P
converter inside the progressive unit.
Main Picture (DVI Pure Digital Mode 1080I)
If the user selects Pure Digital mode than the path for input 5 or 6 will go through
IC3907 (DVI/RGB selector IC) and switch IC4601 to IC4606 and enter the RGB
matrix area for final processing before being sent onto the CRT drives. The sync
signal is separated by IC3901 and passes through switch IC4610 and finally
processed by IC4606.
Main Picture RGB 1080I (DSUB Connector 3)
The signal path for the (DSUB) RGB input 3 connector is exactly the same as DVI
Pure Digital Mode. As you can see in the block diagram RGB cannot be used as a
sub picture or in any other scan or screen mode other than 1080I full.

Audio Input/Output Block Explanation
(See Pages 23 and 24)
Audio Input
All inputted audio signals connect directly to IC2201 the main audio and video
switch located on the Video UCOM PCB. When the user selects an audio and video
source the main UCOM (IC1906) sends a serial command to IC2201 for selecting
the proper input source. Note: The only input that does not go through IC2201 is
the Center Channel Input. After proper input selection by IC2201 the right and left
audio signals go to switch IC2202 the (left/right & center) switch. If the user had
selected in the menu to use the set a center channel for all inputs this switch would
move to the lower position. If the switch is in the L,R position the signals pass onto
the preamp IC5502 located on the power supply PCB. The preamp IC provides
input gain control, tone, bass boost, front surround and operates as an electronic
volume control. From the preamp the signals pass onto the power amp IC1101 and
onto the speakers. DC detection is provided prior to the speaker output to prevent
damage to the speakers. This detection will cause the set to shut down. See page 60
and 62 for details.
Audio Output
The audio output jacks on this set can be used as a Fixed or Variable type. When
used as a Fixed type the L,R audio signals from IC2201 simply pass through the
switch IC2203 and the muting circuit than onto the RCA type jacks located on the
back. If the menu has been set to make the output Variable the signals pass through
the preamp and electronic volume control prior to entering switch IC2203.
Monitor/TV Output
If the system mode is set to OFF (the default setting) this output operates the same
as the normal audio output jacks in fixed mode.
If the user selects (System Mode On) from the menu this output sends the signal
from the tuner only.

1. Procedures
1. When replacing the DIGITAL CONV. Assy, replace the
EEPROM of new DIGITAL CONV. Assy with the EEPROM
of old DIGITAL CONV. Assy.
2. Check the initial data for the convergence adjustment.
3. Perform the coarse adjustment for the green to roughly correct
distortion of the green.
4. Fine-adjust the green to eliminate any distortion. The green
becomes the standard for the red and the blue.
If necessary, repeat steps 3 and 4. Green adjustment is
completed.
5. Perform the coarse adjustment for the red by roughly
converging the red with the green.
6. Fine-adjust the red until the red is completely converging with
the green.
If necessary, repeat steps 5 and 6. Red adjustment is completed.
7. Perform the coarse adjustment for the blue by roughly
converging the blue with the green.
8. Fine-adjust the blue until the blue is completely converging
with the green.
If necessary, repeat steps 7 and 8. Blue adjustment is
completed.
9. Display the green, red, and blue colors at the same time to check
the convergence. Readjust the convergence if necessary.

To move the Horizontal Line upward, press the " " key.
(The value decreases.)
To move the Horizontal Line downward, press the " " key.
(The value increases.)
To move the Vertical Line to the left, press the " " key.
(The value decreases.)
To move the Vertical Line to the right, press the " " key.
(The value increases.)
• To select one color, use the RED key for the red, GREEN
key for the green, BLUE key for the blue. Pressing this key
toggles color muting on or off.
• To mute all the colors, press the DISPLAY key. To release
muting, press the RED, GREEN or BLUE key.
• To erase the cross hatch, press the YELLOW key.
Pressing this key toggles between display of the cross hatch
screen and the input screen.
• To change the brightness of the input screen, use the VOL+ or
VOL- key. The brightness increases with the VOL+ key
(CONTRAST +10) and decreases with the VOL- key
(CONTRAST -40). (The brightness can be changed only in Fineadjustment mode. The brightness of the cross hatch screen
cannot be changed.)
• See "3.3 Coarse adjustment of the green."
Adjust GH STATIC, SKEW and SIZE, and GV STATIC,
SKEW, PIN and SIZE to correct the screen location, tilt, screen
information volume, and peripheral pin distortion.
• See "3.4 Fine-adjustment of the green."
Fine-adjust the linearity of the vertical and horizontal lines
forming a cross at the center of the screen.
Note: In principle, only the selected point is changed in
MANUAL CONVER. mode. However, as the adjusted
data (amount of adjustment) increase, peripheral points
may be affected. So be sure not to greatly change the
adjustment data of one point, but change peripheral points
at the same time. See the examples below.
If an adjustment point is
greatly moved to the right,
Peripheral points may
be affected.
Page 52
2nd step
Adjust so that the vertical lines become straight, taking care to
preserve proper screen information volume and the linearity.
Adjust the right half of the screen first, then the left half.
(See 3.4.)
3rd step
Adjust so that the horizontal lines become straight. Adjust the
upper half of the screen first, then the lower half. (See 3.4.)
4th step
Repeat 2nd and 3rd steps to take total balance. Then the adjustment for the green is completed.
To return from the fine adjustment mode to the coarse adjustment
mode, press the MENU key once, then the DOT key.
Note: When the MENU key is pressed to quit MANUAL
CONVERGENCE mode, the display will be unstable for
several seconds. This is because the adjustment data are
being written to the EEPROMs, and is not a malfunction.
Do not perform any operation (power on/off, or pressing
keys on the remote control unit or on the main unit, etc.)
during this period, because doing so may affect your
adjustment data.

adjustment described in "3.5 Coarse Adjustment of the Red" if
necessary. Make adjustment for each SCREEN mode, and
eliminate distortion to converge with the green.
3.6.1
Press the SET/ENTER key to enter MANUAL CONVERGENCE
mode, and make adjustment in the same manner as with the green.
First, adjust the vertical and horizontal the red lines at the center
of the screen so that they converge with the green center lines.
3.6.2
Adjust the red vertical lines so that they converge with the green
vertical lines. Proceed to adjustment of the right half of the
screen, then the left half. Adjustment should be done from the
part where convergence is greatly dislocated.
3.6.3
Adjust the red horizontal lines so that they converge with the
green horizontal lines. Proceed to adjustment of the upper half of
the screen, then the lower half. Adjustment should be done from
the part where convergence is greatly dislocated.
3.6.4
Repeat the adjustments described in 3.6.2 and 3.6.3 so that all the
red vertical and horizontal lines converge with the green lines.
(Completion of one screen mode)
Page 54
3.6.5
Repeat procedures 3.6.2 through 3.6.4 for the other screen modes.
(Completion of the red adjustment)
3.7 Coarse Adjustment and Fine Adjust ment of the Blue
Make coarse and fine-adjustments of the blue in the same manner
as with the red, described in 3.5 and 3.6.
3.8 Confirmation of Adjustment
After the green, red, and blue adjustments are finished, check
convergence errors with the patterns for all three colors on the
monitor.
Check the patterns in all SCREEN modes, and if any error in
convergence is recognized, readjust convergence in MANUAL
CONVER. mode.
Note: Be sure NOT to change the green pattern during
readjustment.
IMPORTANT!
(1) When all the adjustments are completed, or when adjustment
should be temporarily interrupted, adjustment data must be
written to the EEPROM, in the following manner:
When all the adjustments are completed, or to interrupt adjustment, press the MENU key to quit Convergence Adjustment
mode. The display will be unstable for several seconds, but
this is because the data are being written to the EEPROM.
Wait without doing anything until the display becomes stable,
which means writing of data to the EEPROM is finished.
If the power of the TV is turned off (standby) during
Convergence Adjustment mode (coarse and fine-adjustments),
turn on the TV, enter FACTORY mode, and enter
Convergence Adjustment mode by pressing the SET/ENTER
key. Then press the MENU key. The data will be written to
the EEPROM as described above.
(2) Do NOT turn off the main power during or after convergence
adjustment.
If you do so, the adjusted data may be lost. If the data are
lost, you must make all the adjustments again.
(3) When the CENTER POINT (test cross) or MULTI-POINT
(user convergence) adjustments have been made by a user,
and if the unit enters FACTORY Convergence Adjustment
mode (with the DOT and SET/ENTER keys), the user's
adjustment data will be all cleared and returned to the factorypreset values.
Be sure NOT to enter this Convergence Adjustment mode
except when a repair related to convergence or a repair that
requires convergence adjustment later, is needed.
If you inadvertently enter Convergence Adjustment mode,
readjust the convergence.

DIAGNOSIS METHOD
Power Down Troubleshooting
Various protection circuits are provided for this unit. When these
How to Diagnose a Failure
protection circuits are activated, the power of the unit is shut
down (P.D.: Power Down).
The defective parts can be easily diagnosed by observing the
P.D.
LEDs inside the POWER SUPPLY Assy.
1. D107 in the AWV1960 (For POWER SUPPLY Assy)
2. D111 in the AWV1960 (For DEFLECTION SERVICE Assy)

Failure in the POWER SUPPLY Assy.
There are two main possibilities:
1. Blown fuse(s) in secondary
2. Abnormality in AUDIO OUTPUT

The voltage at the negative electrode of the C1114 and C1117 is
5.5V or more.
Note: The anode of the diode is high only for a short time after the power is turned on until the protection circuits are activated (P.D.)
The LEDs are lit by the HOLD circuit.

In a case when the power cannot be on with no LED lit, check the following:
1. Check if the FU201 fuse in the POWER SUPPLY Assy is blown.
2. Disconnect and check connector P1 (CN407) to see whether STB 5 V is supplied.
If STB 5 V is supplied, replace the VIDEO UCOM SERVICE Assy. If STB 5 V is NOT supplied, replace the POWER SUPPLY Assy.
3. Disconnect and check connector P2 (CN404) to see whether AC CLK is supplied.
If AC CLK is supplied, replace the VIDEO UCOM SERVICE Assy. If AC CLK is NOT supplied, replace the POWER SUPPLY Assy.
When overload detection mechanism is activated, the 10V line is short-circuited. If the power switch is set to ON again in this condition,
there may be a case where the power cannot be turned on, with just a whining sound, and where only the D107 LED in the POWER
SUPPLY Assy is lit. If this happens, first replace only the VIDEO UCOM SERVICE Assy, disconnect the AC cord from the AC outlet or
turn the main power switch OFF, and wait for five minutes. Then, turn on the power again. If the condition is ameliorated, only the
VIDEO UCOM SERVICE Assy is defective. If the same symptom occurs, replace the POWER SUPPLY Assy. In the latter case, the
VIDEO UCOM SERVICE Assy may not be defective.
SIGNAL and TUNER Assemblies can also perform the same as VIDEO UCOM SERVICE Assy.

P.D. (2)
Failure in the DEFLECTION SERVICE Assy.
There are six main possibilities:
1. Blown fuse (s) in secondary
2. Abnormality in the regulator of heater
3. Overload detection
4. H. deflection stopping detection
5. X-ray protection
6. V. deflection stopping
CausesCheck ItemsProbable Defective Parts
Loading of the CONVER. AMP
Check that waveform signals are output from pin 3 and pin 1
of the CN401, CN402 and CN403, and that the DC element is
not added to the signals.

Check that the electric potential of pin 3 and pin 4 of IC401
and IC402 are at the same level when the power is turned on.

If the FU1001 and FU1002 fuses are blown, see the following table:
Note: The anode of the diode is high only for a short time after the power is turned on until the protection circuits are activated (P.D.)
The LEDs are lit by the HOLD circuit.
Note that the power may be shut down when the voltages AC120V, 5V6 and STB5V from the POWER SUPPLY Assy are not
supplied because the DEFLECTION SERVICE Assy is powered by the POWER SUPPLY Assy.
When overload detection mechanism is activated, the 120 V line is short-circuited. If the power switch is set to ON again in this condition,
there may be a case where the power cannot be turned on, with just a whining sound, and where only the D111 LED in the POWER
SUPPLY Assy is lit. If this happens, disconnect the AC cord from the AC outlet or turn the main power switch OFF, and wait for five
minutes.
Be sure to check the fuses in the DEFLECTION SERVICE Assy because one or more may be blown as a result of short-circuiting of the
load circuit of the DEFLECTION SERVICE Assy.
