WARNINGS AND CAUTIONS
CAUTION
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
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.
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, as shown in the illustration below.
Do not grasp the
pedestal or the front
panel of the TV.
If you have connected cables and cords, be sure to
unplug them before moving the TV.
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!!
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.
TRANSPORTER LE TÉLÉVISEUR
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.
Lorsque vous déplacez le téléviseur, placez une
main dans l’orifice de la partie inférieure du
téléviseur tout en tenant la partie supérieure de
l’autre main, comme illustré ci-dessous.
Ne tenez pas le
téléviseur par son socle
ni par le panneau avant.
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.
Si vous avez branché les câbles et les cordons
d’alimentation, veillez à les débrancher avant de
déplacer le téléviseur.
! 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.

SAFETY CHECK-OUT
KDF-37H1000
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.
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 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).

SELF-DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the POWER/STANDBY 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/STANDBY 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/STANDBY 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/STANDBY 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”.)

repairs. When you have completed the repairs, clear the self-diagnostic screen to reset the results to “0”.
Note: The self-diagnostic function will not be able to detect any subsequent faults after completion of the repairs unless the Self-Diagnostic
result display is cleared to reset the results to “0”.
