IMPORTANT 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 1000µ) for the set. 2. To keep the set in a normal operation, be sure to make it function on 22.4KV ±1.5KV (at beam 800µ) 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.
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. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, 10, 11, ......19, 1A, 1B, 1C, 1D, 1E, 1F, 20, 21, ....., 99, 9A, 9B, 9C, 9D, 9E, 9F, A0, A1, ....., B0, ....., C0, ....., D0, .....E0, ....., F0, F1, F2, F3, F4, F5, F6, F7, F8, F9, FA, 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, ... 7.

Gain point b) Tune a grey scale pattern. c) Adjust colour to minimum. 3 7 4 0 d) Fix R-GAIN value to 50. e) Position colourmeter in the the left point of Fig.4. Fig. 4 DC point 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 ± 0.015 Y = 0.300 ± 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 ± 0.015 Y = 0.300 ± 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 the previous one.
NOTE: Locations «R» alter «X» coordinates; «G» alter «Y» coordinates; «B» alter «X» and «Y» coordinates.

DESCRIPTION OF SCHEMATIC DIAGRAM
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.
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.
IMPOTANT SAFETY NOTE: PARTS 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.
CAUTION This circuit diagram is original one, therefore there may be slight difference from yours.
