Service Information
I Protection Circuit
This TV set has a built-in power supply protection circuit. It is provided to protect the TV set in case of a power supply circuit malfunctions. When something abnormality occurs during TV reception, the TV set goes to the stand-by mode. When an abnormality occurs during TV reception, it causes pin 27 of the CPU to go continually Low for about one second. The CPU detects that this has occurred and outputs the signal from pin 31 to switch off the power supply lines.
Releasing the protective circuit and restoring power supply
To release the protective circuit and restore power supply, turn the power to the TV set OFF and then ON again via either the main power switch or the ON-OFF button on the remote control. This will work only if the power supply trouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot be restored and the circuit will have to be repaired. -7-
Service Adjustments with Replacing Memory IC(IC802)
Note: The CPU (IC801) and memory IC (IC802) store the service adjustments data and controls data for each circuit.When the Memory IC(IC802) is replaced, some of the service adjustments should be readjusted to obtain the best performance. The necessary service adjustments are carried out by using the RC handset. Please set up the TV set with following steps [1] to [2].
[1] Initializing Procedure
1. Put a new memory IC. 2. Turn on the TV set. 3. Press and hold the TV/AV Selector on the TV set for more than 2 seconds. The following picture appears on the
screen.

Service Mode Adjustments
Following adjustments should be carried out when the memory IC is replaced. How to enter the service mode and adjust values, please refer to " Entering to Service mode" on page 11.
Item 01 [RF AGC] AGC
NOTE: Do not attempt this adjustment with weak signal. (1) Tune the receiver to most clearest (or strongest) VHF station in your area. Set the brightness and contrast controls to maximum. Set the colour control to minimum. (2) Select [RF AGC] in the service mode. (3) Change value until the snow noise just disappears. (4) Exit from service mode.
Item 05 [V-SCO] V-S CORRECTION
(1) Receive a crosshatch pattern. (2) Select a picture mode of NATURAL by pressing the PICTURE MODE button. (3) Select [V-SCO] in the service mode. (4) Adjust Vertical S-letter Correction so that the difference of "c", "d" and "e" becomes less than 2 mm by pressing the VOLUME + or - button.

Service Adjustments
Following adjustments are not required to readjust when replacing the memory IC.
B-VOLTAGE SUPPLY CHECKING
(1) Connect DC meter to TP-B and the ground. (2) Tune the receiver to an active channel and synchronized picture. Select NATURAL picture mode by pressing the PICTURE MODE button on the remote control. (3) Adjust B-voltage to be 130 ± 1V DC by using VR631. MAIN BOARD

HIGH VOLTAGE CHECK
Note: +B (+130V) Voltage Check and Grayscale Adjustment must be completed before attempting High Voltage Check. (1) Connect high voltage voltmeter negative lead to ground, and connect + lead to anode of picture tube. (2) Tune receiver to an active channel and confirm TV is operating properly. (3) Maximize the beam current by adjusting the contrast and brightness controls to maximum. Confirm high voltage is within 20.0 KV and 22.0 KV at maximum beam current. (4) Eliminate the beam current by adjusting the contrast and brightness controls to minimum. Confirm high voltage does not exceed 23.5 KV at zero beam current. If reading is not within range, check horizontal circuit. No high-voltage adjustment is provided on this chassis.

THE 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.
PRODUCT SAFETY NOTICE: Product safety should be considered when a component replacement is made in any area of a receiver. Components indicated by a mark in this circuit diagram show components whose values have special significance to product safety. It is particularly recommended that only parts specified on the part service manual be used for components replacement pointed out by the mark.

CIRCUIT DIAGRAM NOTICE: 1. All resistance value are in ohms, K=1,000, M=1,000,000. 2. All resistance rated wattages are 1/6W unless otherwise noted. 3. Excepting electrolytic capacitors, all capacitance values of less than 1 are expressed in µ F and more than 1 are pF. 4. All capacitance rated voltages are 50V unless otherwise noted. 5. All inductance values are in µ H. 6. Voltage readings take with a "VTVM" are from point indicated chassis ground. Voltage readings taken by using PAL colour bar signal are with all controls at normal position. Some voltage may vary with signal strength. 7. Waveform were taken with PAL colour bar and controls adjusted for normal picture. Waveforms were taken by using a wide band oscilloscope and a low capacity probe. 8. This circuit diagram covers a basic or representative chassis only. There may be some components or partial circuit differences between the actual chassis and the circuit diagram. 9. Parts specified with "X" are not installed in this model. 10. Parts specified with "J" are just jumper wires.
