Self Diagnosis
Supported model
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to ßash. The number
of times the LED ßashes translates to a probable source of the problem. A deÞnition of the STANDBY/TIMER LED ßash indicators is listed in the
instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review
the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
Diagnostic Test Indicators
When an error occurs, the STANDBY/TIMER LED will ßash a set number of times to indicate the possible cause of the problem. If there is more than
one error, the LED will identify the Þrst of the problem areas.
Results for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, an error has occurred.

POLE DATA
Normally, no adjustments are necessary for these systems. If for some
reason the data is lost, use the following data:
BR
12. CADJ Fix 29
2-4. FOCUS ADJUSTMENT
Confirm neck assembly Z axis position. (See Figure 1)
1. Input a dot signal.
www.Data2S.heSeett4VUi.dceoomMode to STANDARD.
3. Adjust focus VR clockwise (DE-Focus) to confirm that the dot’s shape
is centered. (Figure 2 & 3) Confirm neck assembly rotation by W Board
position. W Board should be level ±1º. Adjust as necessary to balance
dot shape along center horizontal line, then refocus.
4. Input a HD monoscope signal.
5. Confirm center focus with focus VR.
Write the data from any non-vertically compressed mode, then use the
CPY1 function (CXA2170D-4 Item 6) to copy the data to the vertical
compressed modes. V-compressed data is identical to non-v-compressed
data. Service personnel with a trained eye can adjust the
DF or DQP registers to adjust DF phase (Item 7) or DQP
phase (Item 8), respectively, to balance left and right focus.
Refrain from adjusting more than 5 steps from table data below.
Further adjustment indicates a circuit problem -- troubleshoot to
cause. Be sure that Neck Assembly is in the proper location
(See Section 2-4 Figure 1) before changing DF/DQP data or
troubleshooting circuit when DF/DQP is suspect.
