IMPORTANT SERVICING NOTES
Only qualified service personnel are allowed to carry out maintenance and repair of this receiver.

Servicing of High Voltage System and CRT
It is important that the static charge is removed from the high voltage system when carrying out work on the receiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRT cavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from the receiver. Note the following: · The CRT in this receiver employs Integral Implosion Protection. · If the CRT has to be changed it MUST be replaced with the correct type for continued safe working. · DO NOT lift the CRT by its neck. · When handing the CRT, ensure that shatterproof goggles are worn. · Ensure that the CRT is discharge before handling.

X-Ray
This receiver is designed to keep any x-ray emission to an absolute minimum. Some fault conditions and servicing procedures may produce potentially hazardous x-ray radiation levels. This is a problem when in close proximity to the receiver for long periods of time. To reduce any risks associated with this, please observe the following precautions: 1. When undertaking any servicing on this chassis, DO NOT increase the EHT to more than 30 KV, (at a instantaneous beam current of 1500µA ). 2. Ensure that during normal operation the EHT does not exceed 30KV (at a beam current of 1000µA). This level has been preset in the factory. Always check that this level has not been exceeded after carrying out any repair on the receiver. 3. DO NOT replace the CRT with any other type than that specified in the parts listing as this may cause excessive x-ray radiation.

Before returning the receiver to the customer
In addition to the above checks, the following should also be carried out before returning the receiver to the customer. 1. Inspect all the leads to ensure that they are dressed correctly and that they are not obstructed or pinched by any other parts. 2. Ensure that all protective devices are in good condition. These will include nonmetallic control knobs, insulating fish papers, cabinets backs, compartment covers or shields, mechanical insulators, etc.

ADJUSTMENT PROCEDURES
All adjustments to this chassis, except for focus, are carried out in the Service Mode.

· SERVICE MODE
The Service Mode is provided to enable the engineer to correctly set up the receiver to the CRT fitted in the set. Note that these adjustments may vary from one receiver to another. To enter the Service Mode, carry out the following procedure. 1. Connect a test pattern to the antenna terminal. 2. Tune the receiver to this signal. 3. Turn the receiver off using the mains switch. 4. Press volume down and channel up buttons on the front of the receiver at the same time. 5. Keeping these buttons pressed, turn the mains on. 6. When the set starts up it will be in Service Mode. 7. Release the two buttons. · Use the channel up and down buttons to move between the options. · Use the volume control buttons to change the data. · To store the data, use the stand-by button on the remote control. · To exit the Service Mode, turn the receiver off using the mains switch. When the Service Mode is entered the following On Screen Display appears: SERVICE SOFTWARE version . SW on: XXXX SW off: XXXX Hours ON: XXXX The figures displayed in the "XXXX" locations are hexadecimal representations of the number of times that particular function has been executed. For example if the hexadecimal number displayed after "SW ON" was "0E4A", this would correspond to the receiver being turned on 3658 times. Adjustment menu: The following adjustments can be carried out in the Service Mode. · Horizontal Shift · East West Width · Pin Phase · Pin Amp · Upper corner correction · Lower corner correction · Extreme Corner Correction · Vertical Linearity · Vertical angle · Vertical bow · Vertical Amplitude · S Correction · Vertical Shift · Red Cut Off · Green Cut Off · Blue Cut Off · Alter NVM Pag (Page) · Alter NVM Pos (Position) · Alter NVM Val (Value) · Teletext Mix Mode Contrast · Teletext Contrast · OSD Contrast · DVCO Adjustment (Only PAL) · DVCO Adjustment (Only NTSC) · AGC Adjustment · Auto Installation On/Off

SCHEMATIC DIAGRAMS
Description:
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).

IMPORTANT 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.

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.

Waveform Measurement Condition:
1. Test Equipment: Digital Oscilloscope; Colour TV Pattern Generator 2. Test Conditions: CH-12; Colour Bars; 70dB From RF Input 3. TV Condition: Picture and Audio : Settings ! Factory Presets ( Only in Audio Measures: Max. Volume With Unplugged Speakers)
