These servicing instructions are for use by qualifi ed service personnel only. To reduce the risk of electric shock, do not perform any servicing other 
than that contained in the operating instructions unless you are qualifi ed to do so.

Carrying the TV requires at least two people. Do not hold 
by the pedestal or the front panel of the TV. Doing so may 
cause these parts to break off. 

If you have connected cables and cords, be sure to
unplug them before moving the TV.  When moving the TV,  

place one hand in the hole
on the lower portion of the 
TV while grasping the top 
with the other hand.

place one hand to the 
lower portion of the front 
cabinet while grasping the 
top with the other hand.

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.  

 

Ces instructions de service sont à l’usage du personnel de service qualifi é seulement. Pour prévenir le risque de choc électrique, ne pas faire 
l’entretien autre que celui contenu dans le Mode d’emploi à moins que vous soyez qualifi é faire ainsi.

Le transport du téléviseur doit être effectué par au 
moins deux personnes. Ne tenez pas le téléviseur 
par son socle ni par le panneau avant. Ces pièces 
risqueraient de se détacher.   

Si vous avez branché les câbles et les cordons d’alimentation
veillez à les débrancher avant de déplacer le téléviseur.
Lorsque vous déplacez le téléviseur, 

placez une main dans l’orifice 
de la partie inférieure du boîtie
arrière tout en maintenant la 
partie supérieure de l’autre ma

placez une main sur la partie
inférieure du boîtier avant 
tout en maintenant la partie 
supérieure de l’autre main.

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:

1.  Check the area of your repair for unsoldered or poorly soldered 

connections. Check the entire board surface for solder splashes and 
bridges.

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 

mounting hardware have been replaced. Be absolutely certain that 
you have replaced all the insulators.

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.

6.  Check the line cords for cracks and abrasion. Recommend the 

replacement of any such line cord to the customer.

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 
always have low HV.

8.  Check the antenna terminals, metal trim, “metallized” knobs, screws, 

and all other exposed metal parts for AC leakage. Check leakage as 
described below.

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 chassis, must not exceed 0.5 mA (500 microamperes). 
Leakage current can be measured by any one of three methods.

1.  A commercial leakage tester, such as the Simpson 229 or RCA 

WT-540A. Follow the manufacturers’ instructions to use these 
instructions.

2.  A battery-operated AC milliampmeter. The Data Precision 245 

digital multimeter is suitable for this job.

3.  Measuring the voltage drop across a resistor by means of a VOM 

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).

How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-plate 
retaining screw on most AC outlet boxes is also at earth ground. If the 
retaining 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 ohmmeter. The reading should be zero ohms.

If a cold-water pipe is not accessible, connect a 60- to 100-watt 
trouble- light (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 line; the lamp should light at normal brilliance if the screw 
is at ground potential (see Figure B).

The units in this manual contain a self-diagnostic function. If an error occurs, the POWER 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 POWER LED fl ash indicators is listed in the instruction manual for 
the user’s knowledge and reference. If an error symptom is diffi cult to reproduced use the Remote Commander to display the record that is stored at 
the internal NVM to specify the cause of the failure.

Diagnostic Test Indicators
When an error occurs, the POWER 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 POWER LED will identify the fi rst of the problem areas. If the errors occur simultaneously, the one that corresponds to the fewest fl ashes is 
identifi ed fi rst.

Results for all of the following diagnostic items are displayed on screen. (No error has occurred if the screen displays a “0”.)
