14MR10 INSTALLATION AND SERVICE INSTRUCTIONS Note: (1) When performing any adjustments to resistor controls and transformers use screwdrivers or TV alignment tools. (2) Before performing adjustments, the TV set must be on at least 15 minutes. non-metallic CIRCUIT PROTECTION The receiver is protected by a 4.0A fuse (F701), mounted on PWB-A, wired into one side of the AC line input. HIGH VOLTAGE CHECK High voltage is not adjustable but must be checked to verify that the receiver is operating within safe and efficient design limitations as specified checks should be as follows: 1. Connect an accurate high voltage meter between ground and anode of picture tube. 2. Operate receiver for at least 15 minutes at 120V AC line voltage, with a strong air signal or a properly tuned in test signal. 3. Receive a good local channel. 4. The voltage should be approximately, 23.5kV (at Picture MAX, Bright Center condition). If a correct reading cannot be obtained, check circuitry for malfunctioning components. After the voltage test, make Y-mute off to the normal mode. X-RADIATION PROTECTOR CIRCUIT TEST After service has been performed on the horizontal deflection system, high voltage system, B+ system, test the X-Radiation protection circuit to ascertain proper operation as follows: 1. Apply 130V AC using a variac transformer for accurate input voltage. 2. Allow for warm up and adjust all customer controls for normal picture and sound. 3. Receive a good local channel. 4. Connect a digital voltmeter to TP653 and make sure that the voltmeter reads 21.1 ±1.5V. 5. Apply external 27.9V DC at TP653 by using an external DC supply, TV must be shut off. 6. To reset the protector, unplug the AC cord and make a short circuit between TP651 and TP652. Now make sure that normal picture appears on the screen. 7. If the operation of the horizontal oscillator does not stop in step 5, the circuit must be repaired before the set is returned to the customer. 5 14MR10 For adjustments of this model, the bus data is converted to various analog signals by the D/A converter circuit. Note: There are still a few analog adjustments in this series such as focus and master screen voltage. Follow the steps below whenever the service adjusment is required. To enter the service mode and exit service mode. Short JA137&JA138 for 1second and release to switch to the service mode position, and the microprocessor is in input mode. (Adjustment through the I2C bus control.) To exit the service mode, turn the television off by pressing the power button. 1. Service mode. Before putting unit into the service mode, check that customer adjustments are in the normal mode. Use the reset function in the video adjustment menu to ensure customer control are in their proper (reset) position. 2. Service item selection. SERVICE MODE (1) In the Service Mode, Key is used to select the mode in the following oreder. AGC & GEOMETRIC MODE WHITE POINT ADJ. MODE SUB ADJ. MODE OFFSET ADJ. MODE FEATURE OPTION MODE
