WARNINGS AND CAUTIONS
CAUTION
Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield, or carbon painted on the CRT,
after removing the anode.
WARNING!!
An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis. The chassis of
this receiver is directly connected to the ac power line.
! SAFETY-RELATED COMPONENT WARNING!!
Components identifi ed by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for
safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements
published by Sony. Circuit adjustments that are critical for safe operation are identifi ed in this manual. Follow these procedures
whenever critical components are replaced or improper operation is suspected.
ATTENTION!!
Apres avoir deconnecte le cap de l’anode, court-circuiter l’anode du tube cathodique et celui de l’anode du cap au chassis metallique
de l’appareil, ou la couche de carbone peinte sur le tube cathodique ou au blindage du tube cathodique.
Afi n d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout
dépannage. Le chássis de ce récepteur est directement raccordé à l’alimentation du secteur.
! ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
Les composants identifi es par une trame et par une marque ! sur les schemas de principe, les vues explosees et les listes de
pieces sont d’une importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dont
le numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont
l’importance est critique pour la securite du fonctionnement sont identifi es dans le present manuel. Suivre ces procedures lors de
chaque remplacement de composants critiques, ou lorsqu’un mauvais fonctionnement suspecte.

After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
Leakage Test
The AC leakage from any exposed metal part to earth ground and from
all exposed metal parts to any exposed metal part having a return to

connections. Check the entire board surface for solder splashes and

1. A commercial leakage tester, such as the Simpson 229 or
2. Check the interboard wiring to ensure that no wires are “pinched” or
touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps, and
2. A battery-operated AC milliampmeter. The Data Precision 245 digital
mounting hardware have been replaced. Be absolutely certain that
you have replaced all the insulators.
3. Measuring the voltage drop across a resistor by means of a VOM
4. Look for unauthorized replacement parts, particularly transistors,
that were installed during a previous repair. Point them out to the
customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs of
deterioration. Point them out to the customer and recommend their
replacement.
How to Find a Good Earth Ground

screw is to be used as your earth ground, verify that it is at ground
by measuring the resistance between it and a cold-water pipe with an
7. Check the B+ and HV to see if they are specifi ed values. Make sure
your instruments are accurate; be suspicious of your HV meter if sets

If a cold-water pipe is not accessible, connect a 60- to 100-watt troublelight (not a neon lamp) between the hot side of the receptacle and the
retaining screw. Try both slots, if necessary, to locate the hot side on the

or battery-operated AC voltmeter. The “limit” indication is 0.75 V,
so analog meters must have an accurate low voltage scale. The
Simpson’s 250 and Sanwa SH-63TRD are examples of passive
VOMs that are suitable. Nearly all battery-operated digital multimeters
that have a 2 VAC range are suitable (see Figure A).

SELF-DIAGNOSTIC FUNCTION
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 fl ash. The number
of times the LED fl ashes translates to a probable source of the problem. A defi nition of the STANDBY/TIMER LED fl ash 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 fl ash 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 fi rst 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.

+B overcurrent (OCP)
Occurs when excessive current fl ows through R5013. The increase in voltage across R5013 causes the output of Q5004 to go high, and this high
signal goes to the micro.
+B overvoltage (OVP)
IC6505 detects +B OVP condition and turns on Q6522. This sends a high signal to the micro and also shuts down the AC relay.
V-STOP
Occurs when an absence of the vertical defl ection pulse is detected by pin 24 of IC2801 (B Board). Power supply will shut down when waveform
interval exceeds 2 seconds.
White Balance Failure
If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC2801. TV will stay on, but there
will be no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Low B OCP/OVP
Occurs when set 5V is out.
Horizontal Defl ection Stopped
Occurs when either:
1) a +B overcurrent is detected (IC5007), or
2) overheating is detected (Thermistor TH5002).

POLE DATA
Normally, no adjustments are necessary for these systems. If for some
reason the data is lost, use the following data:
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.

2. Check vertical compressed mode.
3. Adjust VPIN if needed.
2-9.4. TWIN MODE/FAVORITE/
INDEX/NORMAL MODE GEOMETRY
CONFIRMATION
TWIN mode and FAVORITE mode use the FULL mode adjustment data.
The key point for TWIN mode adjustment is the blue border appearance.
The left border on the left picture should not be visible when the left
picture is selected. Similarly, the right border on the right picture should
not be visible when the right picture is selected. Balance the HPOS or
HSIZ data for FULL and TWIN mode.
For INDEX mode, however, (XBR sets only), no clipping of the picture
edge should be visible for the small sampled pictures on the right side.
Adjust HSIZ/HPOS to balance FULL and INDEX mode for this. Avoid
displaying the edge of the raster in FULL or FAVORITE mode.
