Service Adjustments
Important Service Notes Maintenance and repair of this receiver should be done by qualified personnel only. Servicing of High Voltage System and Picture Tube When servicing the high voltage system, remove static charge from it by connecting a 10 k W Resistor in series with an insulated wire (such as a test probe) between picture tube ground tag and high voltage lead. (AC line cord should be disconnected from AC outlet.) 1: 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 or 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 30.0 kv, (at beam 1000µA) for the set. 2: To keep the set in a normal operation, be sure to make it function on 25.7 kv ± 1.5 kv (at beam 1300 µA) in the case of the set. The set has been factory -- Adjusted to the abovementioned high voltage. If there is a possibility that the high voltage fluctuates as a result of the repairs, never forget to check for such high voltage after the work. 3: Do not substitute a picture tube with unauthorised types and/or brands which may cause excess X-ray radiation. Before Returning The Receiver Before returning the receiver to the user, perform the following safety checks. 1: Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the receiver. 2: Inspect all protective devices such as nonmetallic control knobs, insulating fish papers, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacity networks, mechanical insulators etc. PIF/SIF/AGC/G2 Adjustment 1: Trap adjustment Adjusting Point T1201: Trap Coil (Adj.-P Trap) T1200:Trap Coil (Adj.-S Trap) 1: Connect sweep generator output to IF in (FA (1)). 2: Connect response cable with detector to collector line of Q1200 (See fig.1) Trap) so that traps are (41.5 MHz) and (32.0 MHz). (See fig. 2) -- ALTER NVM POS. -- ALTER NVM VAL. -- AUTO INSTALLATION To exit service mode, press main switch to off. Adjustment Note: The procedure for making adjustments to Vertical Corrections is as follows: -- Adjust S-CORRECTION -- Adjust VERT. SHIFT -- Adjust VERT. AMPLITUDE Fig. 2 Geometry Adjustment Procedure 2: VCO Adjustment Adjusting Point T1202: VCO Adjust Coil 1: Feed the following signal to pin (1) of connector (FA) in IF unit. Frequency: 39.5 MHz (CW) ± 5 kHz Level approx. 85 dB 2: Adjust T1202 so that voltage at pin (7) (AFT output) of connector (FA) in IF unit is 2.5 ± 0.2v. 3: RF AGC Adjustment Adjusting Point R1216: RF AGC Control 1: Receive "COLOUR BAR" signal. 2: Connect DC voltmeter to Test Point TP1200 (RF AGC). 3: Set AGC control (R1216) to maximum position (memory). 4: Adjust R1216 to obtain voltage of 0.1v below maximum voltage (step 3). 4: G2 Adjustment 1: Receive "MONOSCOPE PATTERN" signal. 2: Connect DC voltmeter with Test probe attenuator ( 1000) to HH1 Test point on PWB-C. 3: Adjust G2 to obtain 730v on HH1. Service Mode Function This mode function is provided to assist with the settings of those adjustments that may vary from one Picture Tube to another, or between models. In order to use the Service Mode 1: Connect Test Pattern signal to antenna terminal. 2: Press main switch to off. 3: Press w and CHv buttons and main switch to on simultaneously. 4. Service mode is now entered. The required adjustments can then be made from the Remote Control Unit. The only buttons required are the following: v CH w for movement in adjustment options menu; v w are used to carry out an adjustment in said menu; ON/OFF is used to memorise a new adjustment. Adjustment menu is as follows: -- SERVICE SOFTWARE -- CROMA-LUNA DELAY -- VERT. SHIFT -- HOR. SHIFT -- E-W WIDTH -- E-W PALABOLA -- E-W CORNER -- E-W TRAPEZOID -- VERT. SLOPE -- VERT. AMPLITUDE -- S-CORRECTION -- RED REFERENCE -- GREEN REFERENCE -- BLUE REFERENCE Chroma-Luma Delay a: Receive Philips pattern signal. b: When volume-up button is pressed, luma phase delays. c: When volume-down button is pressed, chroma phase delays. d: Adjust the Chroma-Luma delay. Vert.

Hor. Shift a: Receive Philips pattern signal. b: When volume-up button is pressed, picture moves to the left. c: When volume-down button is pressed, picture moves to the right. d: Adjust the horizontal location to obtain picture centring (fig. 4). E-W Width a: Receive Philips pattern signal. b: When volume-up button is pressed, horizontal scanning increases. c: When volume-down button is pressed, horizontal scanning decreases. d: Adjust the horizontal amplitude to obtain 9% overscan (fig. 5). E-W Parabola a: Receive Philips pattern signal. b: When volume-up button is pressed, slide pincushion changes from pincushion to barrel shape. c: When volume-down button is pressed, slide pincushion changes from barrel to pincushion shape. d: Adjust the E-W PARABOLA to obtain condition as in fig. 6. E-W Corner a: Receive Philips pattern signal. b: When volume-down button is pressed, slide pincushion changes from pincushion to barrel shape. c: When volume-up button is pressed, slide pincushion changes from barrel to pincushion shape. d: Adjust the E-W CORNER to obtain condition as in fig. 7. E-W Trapezoid a: Receive Philips pattern signal. b: When volume-up button is pressed, slide pincushion changes. c: When volume-down button is pressed, slide pincushion changes. d: Adjust the E-W TRAPEZOID to obtain condition as in fig. 8. Vert. Amplitude a: Receive Philips pattern signal. b: When volume-up button is pressed, vertical size of picture increases. c: When volume-down button is pressed, vertical size of picture decreases. d: Adjust the vertical size to obtain overscan as in fig. 9. S-Correction a: Receive Philips pattern signal. b: When volume-up button is pressed, upper and lower scanning decreases, and centre scanning increases. c: When volume-down button is pressed, upper and lower scanning increases and centre scanning decreases. d: Adjust the S-correction to obtain a balance between upper, lower and centre (fig. 10). The following adjustments are only required when the Picture Tube is changed. Red Reference/Green Reference/Blue Reference a: Adjust G2. b: Tune in white card. c: Adjust colour to minimum. d: Position colourmeter in centre of screen. e: Using brightness and contrast buttons, select a luminance of 120 NITS. f: Operate again in Service Mode and select location RED REFERENCE/GREEN REFERENCE/BLUE REFERENCE to obtain colour co-ordinates: X = 0.290 ± 0.0015 Y= 0.284 ± 0.015 g: Exit Service Mode and check colour coordinates `X' and `Y' at 20 and 120-NITS. It may be necessary to repeat procedure. Note: Locations: RED REFERENCE alter `X' co-ordinate; GREEN REFERENCE alter the `Y' co-ordinates; BLUE REFERENCE alter the `X' and `Y' co-ordinates.
