Black Screen, Distortion, or
Misconvergence Caused by CRT
Arcing (6/97)
Issue:
an internal arcing within the cathode ray tube (CRT) may
reset some control values in the monitor's internal
microcontroller chip. This can cause the screen to go blank,
cause some geometry distortion, or cause the convergence to
become intolerable.
The monitor is most likely to experience this problem
within the first few hours or days after installation.
However, it is possible to have this problem anytime during
the life of the product. CRT arcing is normal and expected on
all CRT-type monitors.
On a limited number of AppleVision 1710 monitors,

Solution:
the front panel of the monitor will eliminate the screen
distortion.
Otherwise, shut down the monitor and unplug the power cord
and ADB cables from the back of the monitor. Count to ten.
Then plug in the power cord and ADB cables. This action
should remove all symptoms. If the blank screen symptom
persists, contact Apple Technical Support.
CRT arcing is normal and expected on a certain percentage of
displays from all manufacturers. An arc happens when
residual particles inside the CRT are dislodged. This usually
occurs when the display has experienced physical vibration
like transportation. The arc time is short and there is no
safety hazard because the arc is contained inside the sealed
glass of the CRT. This arcing will not cause permanent
damage to the display.

Troubleshooting General/ - 1
General
The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts in the order of most likely solution, try
the first cure first. Verify whether or not the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(Note: If you have replaced a module, reinstall the original module
before you proceed to the next cure.)
If you are not sure what the problem is, or if the Symptom Charts
do not resolve the problem, contact Apple Technical Support.
Troubleshooting First Checklist/ - 2
First Checklist
Important:
returned for repair are found to be fully operational. Read this
checklist before you return a module, and prevent needless module
replacement and unnecessary time delays.
Many AppleVision 1710AV and 1710 display modules
The AppleVision 1710AV/1710 Display is not
compatible with all computers.
This display works with both Macintosh and IBM PC-compatible
computers. A video card may need to be installed to use this display
with some computers. For more information, see the computer
manual.
The display is preadjusted to work with any computer that has the
following timing ranges:
• Horizontal scan rate of 30-80 kHz
• Vertical refresh rate of 50-120 Hz
For best display performance, operate the display in one of the
standard Macintosh screen resolutions listed in the Specifications
chapter in this manual.
The CRT raster will not always resemble a
perfect rectangle.
CRT tolerances allow for some distortion. Additional distortion can
be caused by magnetized metal objects (desks, file cabinets, etc.).
Move the unit to a different location if you notice raster bowing or
bent raster edges.
Jitter, faint lines, or screen movement can be
caused by external interference such as
electronic devices and fluorescent lights
Fluorescent lights, other monitors, or electronic appliances such
as coffee makers and copy machines can cause raster distortion.
Move the unit to another room or building to help determine if
external interference is the source of the problem.
Note:
If the raster has shifted up/down or right/left only, adjust
it using the user controls. However, keep in mind that if you then
move the monitor you may need to readjust the centering controls.
If the display changes (for better or worse) when you move it to
another location, the environment is the source of the problem.
Relocate the monitor or move the distortion-causing object.
.
Troubleshooting First Checklist/ - 3
A maladjusted screen can mimic the
symptoms of main deflection board or CRT
failures.
By performing the adjustment procedures, you might determine if
one or more of the adjustments is the cause of the problem.
Variances in screen color and brightness are
usually caused by the setup controls or the
environment.
Screen color purity over the entire screen is never perfect. CRT
tolerances allow for some distortion.
Try adjusting the rotation, brightness, or contrast to reduce or
eliminate the symptom.
Color imperfections can be caused by magnetized metal objects
(desks, file cabinets, etc.). Move the unit to a different location if
you notice color blotches or a change in brightness on an area of
the screen. If the display changes (for better or worse) when you
move it to another location, the environment is the source of the
problem. Relocate the monitor or move the distortion-causing
object.
If you suspect a failure, check the monitor
serial number before replacing modules
• If the monitor serial number is between SG522xxxxxx and
SG536xxxxxx, contact Apple Technical Support (1-800919-2775, option 6) to expedite replacement of the head unit
or whole unit.
• If the number is SG537xxxxxx or greater, refer to the
Symptom Charts to troubleshoot the monitor.

Troubleshooting Symptom Charts/Audio (1710AV only) - 9
Audio (1710AV only)
The symptoms associated with a defective sound enclosure are
relatively easy to diagnose. Following are typical symptoms of a
defective audio system. However, some of these symptoms can also
be caused by defective speakers, the built-in microphone, and
connectors or cables that plug into the sound enclosure.
• No sound left/right channel
• No recording capability (internal/external microphone)
• No volume/bass/treble control
• Sound distortion
• No gain control (line in and external microphone)
• Loud popping sounds
• Headphones have no sound
Miscellaneous
Microphone doesn’t
work
1 Without removing rear housing, disconnect microphone from
bezel of AppleVision 1710AV Display.
2 Connect microphone to known-good AppleVision 1710AV
display to verify whether it works.
• If microphone doesn’t work, replace it. Because
microphone cable might also be damaged, go to step 3.
• If microphone works, check microphone cable (as
described in the next step).
3 With microphone disconnected, use a DC voltmeter to check
contacts on microphone connector that is secured inside
monitor bezel. The voltmeter should measure 8 volts DC.
4 If voltmeter reads 0 VDC, remove sound enclosure, connect
extension cables to head unit, and measure voltage at the
microphone connector (BA10) on sound board.
• If voltmeter measures 8 VDC, replace microphone cable

Symptom Sets
A small percentage of AppleVision 1710 and AppleVision 1710AV
monitors malfunction either during startup or immediately after
color recalibration.
When this malfunction occurs, the monitor can display two
different sets of symptoms:
Symptom Set 1
• No raster (black screen).
• Power indicator light is on.
• Rustling or crackling sound emitted when the monitor is turned
on or off.
high voltage is not present, the Recovery Utility will not solve
the problem. In that case, refer to the symptom “No raster
(screen is black); power indicator light on” in this chapter.
Note:
This sound indicates high voltage is present. If
Symptom Set 2
• Screen is one predominant color (magenta, green, red, blue,
etc.).
• Instead of being black, the left and right edges of the screen
might exhibit some luminance.
If your monitor displays either set of symptoms, use the
AppleVision Recovery Utility to correct the problem.
Troubleshooting AppleVision Recovery Utility for Malfunction During Startup or
Using the AppleVision Recovery Utility
To perform the recovery procedure, you need
• Macintosh computer that can support two monitors (unless you
have Symptom Set 2)
• Malfunctioning AppleVision 1710 or 1710AV monitor
• Known-good monitor (any model)
• AppleVision Recovery Utility application located on the Service
Source Companion CD: Diagnostics Utilities folder
• AppleVision Setup control panel application installed on the
Macintosh computer
Important:
Macintosh computer model. Copy the image to a blank disk using
Disk Copy 4.2. The correct image is determined by the type of
computer used with the AppleVision Display:
• For PowerMac 7100/80 and AV, 8100/100/110 and AV
computers, use the file AppleVision Recovery.image 1.
• For Quadra, Centris, PowerBooks (except 190, 2300, 5300),
and first-generation Macintosh computers, use the file
AppleVision Recovery.image 2.
• For PowerBook 190, 2300, 5300, PowerMac 7200, 7500,
7600, 8500, and 9500, use the file AppleVision
Recovery.image 3.
• For PowerBooks with external video support or other
computers with a second display connected, use the file
AppleVision Recovery App.
Follow these steps to recover the monitor:
1 Connect a known-good monitor to the Macintosh’s built-in
video port (unless you have Symptom Set 2).
2 Connect the malfunctioning AppleVision 1710 or 1710AV
monitor to the Macintosh’s second video port. Connect the
monitor’s ADB cable connector to the Macintosh’s ADB port.
3 Turn on the Macintosh system, and confirm that the known-
good monitor displays the menu bar and Finder desktop.
4 Run the AppleVision Recovery Utility. After recalibrating,
the 1710(AV) monitor should display an active raster.
5 Press a button on the left side of the 1710(AV) front panel
to open the AppleVision Setup control panel. Click the Color
button.
Be sure to use the correct Recovery image for your
Troubleshooting AppleVision Recovery Utility for Malfunction During Startup or
6 Recalibrate the 1710(AV) monitor by clicking the
recalibrate button. The screen should recalibrate
successfully and return to an active raster.
• If the recalibration is successful and the screen returns to
an active raster, the monitor is recovered and no further
service is required.
• If the recalibration is successful (active raster returns)
using the Recovery Utility, but the screen returns to black
(or color) after the recalibration check, call Apple
Technical Support at 1-800-919-2775 for assistance.
7 Restart the Macintosh. Confirm that the 1710(AV) monitor
has an active raster through the entire restart cycle and that
the Finder desktop is active after the cycle is completed. If
the monitor was recovered using the Recovery Utility and the
screen returns to black or color during start-up, call Apple
Technical Support at 1-800-919-2775 for assistance.
Troubleshooting Diagnosing A Suspected Hardware Problem/Using the AppleVision
Diagnosing A Suspected Hardware Problem
After ruling out other possible cures (that is, you have already
checked cable connections, power, AppleVision software, and other
possible front-of-screen cures), use the following procedure to
help determine and resolve hardware problems. (See the
flowchart at the end of this chapter for a simplified depiction of
this process.)
1 If the problem is a completely black screen, connect another
known-good display (not an AppleVision or ColorSync
display) as follows. Use a computer that has a video card so
you can connect both displays to the computer. Connect the
known-good display to the built-in monitor port; connect the
1710(AV) display to the video card connector.
2 If the problem involves a partially visible screen (you can
see the screen desktop and read the screen icons), there is no
need to connect a second display.
3 Turn on the computer and the monitor(s). If using a second
display, confirm that the known-good display is set up as the
main startup screen (Monitors & Sound control panel).
4 Open the application called Display Service Utility (from the
Diagnostics Utilities folder on the Service Source Companion
CD).
5 Select AppleVision 1710/1710AV pattern selections.
6 Click Create File. A message appears explaining that the
process will take about 3 minutes.
Troubleshooting Diagnosing A Suspected Hardware Problem/Using the AppleVision
7 If a dialog box appears that says the Display Service Utility
(DSU) is unable to communicate with the display, then
remove the monitor housing, and use a multimeter to
measure the voltage between chassis ground and resistor RL1
on the end closest to capacitor CP17 on the main deflection
board:
• If the voltage measures 11.5 V to 12.5 V, replace the CRT/
video board
- If the problem is gone, adjust the display as described in
“Adjusting the Display after Replacing the CRT/Video
Board” in this chapter.
- If the problem persists, reassemble the monitor, and
return the display for whole unit or head unit
replacement (following the service strategy in your
region).
• If the voltage measures less than 11.5 V or greater than
12.5 V, replace the main deflection board (refer to the
Take Apart chapter). Reconnect the display to the computer
and turn on the computer and monitor.
- If the problem is gone, adjust the display as described in
“Adjusting the Display after Replacing the Main
Deflection Board” in this chapter.
- If the problem persists, reassemble the monitor, and
return the display for whole unit or head unit
replacement (following the service strategy in your
region).

8 If the Create File process finishes successfully, click Adjust
Geometry. Clicking this button causes the DSU to
automatically verify EHT (high voltage). Use a probe to
measure the high voltage. (Refer to “Checking High Voltage”
in this chapter.)
• If the high voltage is okay, replace the CRT/video board and
adjust the display (see “Adjusting the Display after
Replacing the CRT/Video Board” in this chapter). If the
hardware problem still exists after completing the
adjustments, return the display for whole unit or head
unit replacement (following the service strategy in your
region).
• If there is no high voltage, replace the main deflection
board and adjust the display (see “Adjusting the Display
after Replacing the Main Deflection Board” in this
chapter). If the hardware problem still exists after
completing the adjustments, return the display for whole
unit or head unit replacement (following the service
