The chassis in this receiver is partially live. Alwais use an isolation transformer when
servicing this chassis.
To prevent electric shock, do not remove cover. No user-serviceable parts inside. Refer
servicing to qualified service personnel.

IMPORT ANT SERVICE NOTES

Maintenance and repair of this receiver should be done by qualified service personnel only .

SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE

When servicing the high voltage system, remove static charge from it by connecting a 10K ohm resistor in
series with an insulated wire (such as test probe) between picture tube ground tag and high voltage lead.
(AC line cord should be disconnected from AC outlet).

1. The Picture tube in this receiver employs Integral Implosion protection.

2. Replace with tube of the same type number for continued safety .

3. Do not lift picture tube by the neck.

4. Handle the picture tube only when wearing shatterproof goggles and after discharging the high
voltage completely .

X-RAY

This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions
and servicing may produce potentially hazardous radiation with prolonged exposure at close range, the following
precautions should be observed:

1. When repairing the circuit, be sure not to increase the high voltage to more than 25.5 KV , (at beam
1000µΑ) for the set.

2. T o keep the set in a normal operation, be sure to make it function on 22.4KV
800µΑ) in the case of the set. The set has been factory - adjusted to the above mentioned high
voltage. Always check the high voltage if there is any possibility that it might have changed as a
result of the repair.

3. Do not substitute a picture tube with unauthorized types and/or brands which may cause excess
X-Ray radiation.

±1.5KV (at beam

BEFORE RETURNING THE RECEIVER

In addition to the above checks, the following safety checks should also be carried out before returning the
unit to the user .

1. Inspect all leads and dress to make certain that the leads are not pinched or that hardware is not
lodged between the chassis and other metal parts.

2. Inspect all protective devices such as non-metallic control knobs, insulating fish papers, cabinet
backs, adjustment and compartment covers or shields, insolation resistor-capacity networks,
mechanical insulators etc.

Bear in mind that, for storage location indication a hexadecimal numerical system is used, instead of a
decimal system.

FB, FC, FD, FE, FF.
From the last location FF to the first 00 can be reached by increasing and from first to last by decreasing.
Once the storage location to be varied has been selected, its value can be modified by the bits that form
part of the storage location numerical buttons, numbers «0» to «7», respectively. This swithches the binary
number from and between 0 and 1 each time one of the buttons is pressed.

«0»:20=1, «1»: 21=2, «2»: 22=4, ...

Adjustment to a selection can be made by pressing buttons ∨ ∧.

8. For «d» thru «f» selections:
Adjustment to a selection can be made by pressing button ∧.

•COLOUR ADJUSTMENT (BKGD) PROCEDURES

The following adjustments are required when the Picture Tube or IC801 are replaced, or
may be necessary after adjustment of the G2 voltage.

1. «B-GAIN», «G-GAIN»

a) Adjust G2.
b) Tune a grey scale pattern.

Gain point

c) Adjust colour to minimum.
d) Fix R-GAIN value to 50.
e) Position colourmeter in the the left point of Fig.4.
f) Using brightness and contrast buttons, select a luminance of ≈120 nits.
g) Operate again in Service Mode and select location B-GAIN and
G-GAIN to obtain colour coordinates:

X = 0.290
Y = 0.300

± 0.015

± 0.015

h) Exit Service Mode and check colour coordinates «X» and «Y» at 20 and 120 nits. It may be
necessary to repeat the same procedure or re-adjust the cuts as show the be below one.

2. «G-DC», «R-DC»

a) Adjust G2, in the case that it has not been made previously.
b) Tune a grey scale pattern.
c) Adjust colour to minimum.
e) Position colourmter in the the right point of Fig.4.
f) Using brightness and contrast buttons, select a luminance of ≈20 nits.
g) Operate again in Service Mode and select location G-DC and R-DC to obtain colour
coordinates:

X = 0.290
Y = 0.300

± 0.015

± 0.015

DESCRIPTION OF SCHEMATIC DIAGRAM

37GQ-20S
37GQ-21S

SAFETY NOTE:

1. DISCONNECT THE AC PLUG FROM THE AC
OUTLET BEFORE REPLACING PARTS.

2. SEMICONDUCTOR HEAT SINKS SHOULD BE
REGARDED AS POTENTIAL SHOCK HAZARDS
WHEN THE CHASSIS IS OPERATING.

IMPOTANT SAFETY NOTE:

P ARTS MARKED WITH « » ( ) ARE
IMPORTANT FOR MAINTAINING THE SAFETY
OF THE SET. BE SURE TO REPLACE THESE
PARTS WITH SPECIFIED ONES FOR
MAINTAINING THE SAFETY AND PERFORMAN­CE OF THE SET.

WAVEFORM MEASUREMENT CONDITION:

Colour bar genetator signal of 70 dB from RF input.

NOTE:

1. The unit of resistance «ohm»is omitted (K=1000
ohms. M= Megaohm).

2. All resistors are 1/8 watt. unless otherwise noted.

3. All capacitors are

µF, unless otherwise noted (P=

µµF).

4. The capacitor with Part No. RC-FZ9XXXBMNJ is
designed to with stand 63V.

SERVICE PRECAUTION:

THE AREA ENCLOSED BY THIS LINE ( )
IS DIRECTLY CONNECTED WITH AC MAINS
VOLTAGE.
WHEN SERVICING THE AREA, CONNECT AN
ISOLATING TRANSFORMER BETWEEN TV
RECEIVER AND AC LINE TO ELIMINATE
HAZARD OF ELECTRIC SHOCK.

CAUTION
This circuit diagram is original one,
therefore there may be slight difference
from yours.
