Troubleshooting - General Notes & Guidance:
 If the display does not present the proper information upon completing the
instructions of this guide, there are a few tests that can be used to isolate the
issue. First, the self-test function will be used to demonstrate that the LCD panel,
the main board, and the back light interface are all working properly. It also
shows that the proper power is being supplied and that all internal cables are
properly connected. Perform the self-test in the following way:
1. Connect power cable but do not connect signal cable
2. Turn machine and control power ON
3. If screen is dark (OFF), on the "user" control panel, press the "Power" button
4. One of the following should be observed:
• The CCFL or LED for panel back lighting should power up (some flicker
should be observed)
5. If nothing happens, wait a few seconds and press the "Auto" button
6. The screen should now cycle through different solid color backgrounds, if this
does not happen:
• Check that power is applied properly.
• Check that the signal cable is not connected. If it is, disconnect cable and
start from step 1.
1. If all checks have been performed and the self-test sequence is not occurring,
the unit should be returned to Precision Zone for analysis.
 Once the self-test has provided assurance that monitor is working properly and
that a signal can be applied, connect signal cable and note proper display of
data. If data is present, but not displayed properly, press the "AUTO" button on
the user control panel. The main board will realign the data based on input signal
and properly display the data. If the data is not present, there are a few reasons
this may occur:
1. If the signal presented does not have the corresponding horizontal and vertical
"refresh" frequencies that can be matched to the LCD panel, the screen will not
display anything. The LCD panel will typically be black (but in some cases
blue)
• Check if LCD panel backlight is still on
2. If the backlight is ON, the input signal is missing. Verify that the signal source
is ON and operating properly. Verify that input signal cable is wired properly
and that horizontal and vertical sync signals are being presented to the proper
pins.
3. Contact Precision Zone for additional assistance if all appears to be proper
and monitor is still not displaying data properly.
