COMPONENT NUMBERING SYSTEM

Serviceability of this chassis is enhanced by road mapping on the top and bottom of the circuit boards. In
addition components are marked as to the Component Type and generally marked as to their circuit. The
operation and features of the “ITC” chassis is similar to the “CTC” series chassis. However the component
numbering system is different than that in the past in the “CTC” series chassis but is similar to the component
markings of the “TX” series chassis. The component numbering for the chassis reflects the component’s
type and use as to the general circuit areas it is used. The component labeling system is described below:

COMPONENT DESIGNATION: X X XXX

PROCEDURES

ALIGNMENT PROCEDURES

Operating Conditions

Unless otherwise noted, the following conditions
must be observed when aligning the ITC222 chassis:
Chassis must be operated from a 120V AC isolation
transformer, with line volt age set to 120V AC (±2.0V).

Picture controls (black level, contrast, etc.) must be
set to factory presets via the Picture Quality menu.
Procedures must be performed in the sequence
given. A 10X probe must be used for oscilloscope
and frequency measurements.

The audio output leads must not be shorted together
or to ground with the chassis on. All video signals
must have -40 IRE sync tips unless specified
otherwise. Chassis AC power must be removed for
10 seconds before disconnecting any cable.

A 3-minute warm-up is required for chassis or
module related alignments. A 15-minute warm-up
is required for Kine or Convergence related
alignments.

Required T est Equipment

- Dual-Trace Oscilloscope

- Digital Voltmeter

- Frequency Counter

- Audio Signal Generator

Figure 1 - Centering Rings

First make certain the replacement CRT and yoke
are assembled and placed back in the mounting as
close as possible to the original CRT and yoke. At
this point having the convergence pattern on screen
will assist in the mechanical mounting.

Using the centering rings and observing the conver­gence pattern, rotate and move the pattern until the
replacement color overlays as close as possible to
the two colors not replaced. Moving the ring tabs
together around the neck of the CRT draws the ras­ter in small circles. Spreading the tabs ap art moves
the raster in more linear angles. The closer the tabs
are together, the less affect on the CRT beam they
have.

When the raster is as close as possible fix the mag­nets with paint or nail polish to prevent further move­ment.

VI-6

After fixing the magnets, if gross geometry errors
are apparent, geometry alignment is indicated. If
the raster is close, use the "Auto-convergence" fea­ture provided in the consumer menu to re-align con­vergence. This should correct most minor geom­etry problems. Follow auto-convergence with the
consumer red and blue centering adjustments, then
evaluate the raster again.

In most cases convergence will now be acceptable.
If only slight convergence errors are noted the tech­nician should enter the manual digital convergence
menu and begin "touch-up" of the screen.

If gross geometry errors are still apparent re-evalu­ate whether the errors are noticable on the replace­ment CRT or whether they are global, affecting all
three CRT's. If the errors affect all three CRT's a full
geometry alignment is indicated. If the errors only
affect one CRT, particulary the replacement, return
to the mechanical placement and centering ring ad­justments and begin those procedures again.

Rotate Tabs Together

of the following modes, Tuner, Comp 1H,
Comp 2H, DVI and AUX_RGB (if DVD
option is installed).

16. The Drive Level Alignment is preset
according to the CRT type selected and
does not need to be adjusted.

17. Before exiting the Video Alignment
Submenu, check Store to save all
alignments.

Before attempting the Video Alignment s, allow the
instrument to warm up for a minimum of 15 minutes.

1. Tune the instrument to receive a
crosshatch pattern.

5. Place the instrument in the Field Service
Mode.

6. Enter the Video submenu.

7. Select G2 adjustment.

8. Adjust Screen control until retrace lines
become visible, then adjust to make retrace
lines invisible.

9. Press any key to exit the G2 alignment
mode.

10. Select a pluge test pattern. Pattern should
have a 0% background with a -2% and
+2% bar.

11. Adjust Scaling Black Level to make the ­2% bar invisible, keeping the +2% bar
visible.

Color T emperature

Color Temperature for the ITC222 is similar to past
chassis. Some form of staircase pattern similar to
the following figure is required. Proper identification
of the “0” (if available) and “7.5” or “setup” bars on
screen and the waveform produced on the cathodes
of the CRT will be needed. Consult the specifications
manual for the pattern generator used to confirm
the location of these bars.

The oscilloscope waveform shows the relationship
between the bars and the video signal at the
cathodes of the CRT. This waveform is present on
all three cathodes. With the oscilloscope adjusted
to provide a full peak to peak readout of the
waveform at the horizontal rate, the 7.5 IRE setup
bar will the critical area. Be certain this bar can be
identified using the equipment available. If a 7.5 IRE
bar is not available, 10 IRE may be used.

VI-8

It should be noted that bar patterns differ . Some vary
from 10 to 100 IRE in various steps and in different
directions, but most should have an identifiable 7.5
to 10 IRE bar.

The purpose of the color temperature setup is to
assure uniform gray level from black to the brightest
scenes. If a uniform gray screen is displayed, no
matter the brightness level, no tinting in either red,
green or blue direction should be apparent. This is
known as “color tracking”. Once the proper color
temperature is set, AKB will maintain the cutoff of
the CRT to assure proper low light performance.

Black Cutoff R/G, Whitepoint R/G/B Setup
(Recommended Method)

1. Apply a gray test pattern giving a 12 IRE
flat window. Connect Colorimeter near the
center of the screen.

2. Adjust Black Offset R and Black Offset G to
obtain the following color coordinates:

Direct View Projection TV

X 0.282 0.283
Y 0.298 0.296

3. Apply a gray test pattern giving a 50 IRE flat

window.

4. Adjust Whitepoint R, G, and B for the
following color coordinates:

Direct View Projection TV
X 0.282 0.278
Y 0.298 0.291

Note: This alignment must be done in the following

modes, RF (NTSC), Comp 1H, Comp 2H,
DVI and AUX_RGB (If unit has DVD option
installed).

Black Cutoff R/G, Whitepoint R/G/B Setup
(Alternative Method)

1. Apply a vertical gray bar staircase pattern
(at least 8 bars from “7.5” to “>75” IRE).
Identify the 7.5 IRE bar location. It is the
“black” or “cutoff” bar . For these adjustments
this bar and the next brighter bar will be
used. On most patterns the remainder of
the bars will progressively become brighter.

2. Adjust Black Cutoff R or Black Cutoff G until
any tinting disappears from the black bar.
When properly adjusted the adjacent bar
should be a very low level gray with no color
tinting.

3. Now observe the brighter portions of the
bars. Adjust Whitpoint R, G, or B to remove
any signs of tint in the higher brightness
bars. Observe the bars for signs of CRT
overdrive. Some compromise may be
required, but the higher IRE bars should be
as free from color tinting as possible.

Note: There are separate color temperature

alignments for RF (NTSC), Comp 1H, Comp
2H, DVI and AUX_RGB (If unit has DVD
option installed).

Peak White Alignment

1. Apply a white centered pattern of 100 IRE
2% of the picture surface on a dark
background.

2. Adjust for peak white at center of the screen.

3. Check Scaling Black Level, Whitepoint,
Black Offset and Peak White adjustments.
It may be necessary to adjust these
alignments several times for optimum
performance.

VI-9

Note: This alignment must be done in the following

modes, RF (NTSC), Comp 1H, Comp 2H,
DVI and AUX_RGB (If unit has DVD option
installed).

Full White 3/4 Alignment

1. Insert a full white pattern of 100 IRE through
RF. (Instrument will automatically set to ¾
mode).

2. Adjust for full white across the screen.

T ext Contrast, Contrast Max, Scaling Contrast
Alignments

1. Insert a white centered pattern of 100 IRE,
2% of the picture surface with a black
background.

2. Adjust for peak white.

3. Contrast Max and Scaling Contrast are
preset according to the CRT type selected
and do not need to be adjusted.

Event

If a run-time event occurs, its error code will be stored
in the NVM. The stored event codes can be read in
one of two methods. The first is with the event menu.
The last five event codes will be displayed, along
with a time stamp from the run time counter. The
time stamp will display the last occurrence of a par­ticular event. The time stamp is displayed as “Run
Hours”. An event counter counts how many times
that event has occurred. The counter will not count
beyond 255. The most recent event code is displayed
on top. To clear the event codes from memory, se­lect the Clear Event Codes box. A long press will
clear all stored codes.

Only the last error code stored in the NVM can be
read with this method. The LED will blink two
separate digits.
Example, if the error code of 23 is the last error code
stored

in the NVM, the LED will have 2 short flashes,
followed by a short pause. Then will flash 3 times,
followed by a long pause. This will be repeated 4
times.

First allow the instrument to sit unplugged for 60
seconds. At plug in the LED will first blink twice to
indicate microprocessor has reset. When an attempt
is made to power up, the instrument will attempt 3
times to start. The LED will display a series of flashes
followed by the error codes. The LED will flash the
error code 4 times.

ITC222 Dead Set Troubleshooting

The first step in all troubleshooting is to determine what is or is not working. The following information
should be used when the set is totally dead or nothing happens when the power button is pushed.
1 Once the main fuse has been eliminated as a potential problem, measure the +1.8Vs
supply at IP551 on the SSB board:

Figure 6; STBY 1.8V Location

The +1.8Vs voltage is the main supply for the main microprocessor , IR001. Without it, nothing will fire up.
If missing, troubleshoot the Standby Power Supply.
2 Once the +1.8Vs supply has been confirmed as operational, check the clock (pin 6)
and data (pin 5) lines to the main NVM, IR005.

Figure 7; Clock and Data Location

VIII-2

In the first 100mS after AC power is applied the CLOCK and DATA lines must rise to very near +5V and
have at least few cycles of data. This indicates communication between the main microprocessor and
NVM (EEPROM). Note only a limited amount of Data is transferred when AC is applied. Communications
will cease until the power ON button is pressed to start the chassis. However, the short amount of dat a
transfer between the microprocessor and NVM is a good indication that communications between the
main microprocessor, ROM and RAM were successful and the main microprocessor is alive.
From observing clock and data activity , there are two failure indications. First, if there were no signs of
data or clock suspect the main microprocessor is defective. However if there is constant communications
it indicates the microprocessor is trying to communicate with the NVM and cannot. Suspect a defective
NVM (EEPROM). In either case the SSB should be replaced.
NOTE: In some cases it may be required to check the communications again. To do so requires the main
micro be in a zero voltage state. Be aware the mains doubler can hold a significant voltage for a long
period of time. AC must be removed for at least several minutes to give the +1.8Vs supply time to com­pletely bleed off. To save time the +1.8Vs supply may be bled by shorting CP555 on the SSB module.
Check the +1.8Vs supply to make certain it is less than +0.2V before attempting to reapply AC power.

Figure 9; Inf_Pow_Fail

Figure 8; Location of Reset Cap

Power Fail (INF_POW_FAIL)

Another useful preliminary check is the INF_POW_FAIL voltage located on the PSD board. The voltage
monitors an unregulated rectified output from the +7Vs winding. This can be located on one end of RP231
as shown. During normal operation this voltage will be less than -1V and normally stays around -2V.
INF_POW_FAIL can indicate severe loading problems on the standby supplies. Absence of a negative
INF_POW_FAIL signal will not allow the chassis to start.
