INSTALLATION AND SERVICE INSTRUCTIONS
Note: (1) When performing any adjustments to resistor controls and transformers use non-metallic
screwdrivers or TV alignment tools.
(2) Before performing adjustments, the TV set must be on at least 15 minutes.
CIRCUIT PROTECTIONHIGH VOLTAGE CHECK
The receiver is protected by a 5.0A fuse (F701),High voltage is not adjustable but must be checked
mounted on PWB-C, wired into one side of the to verify that the receiver is operating within safeAC
line input.and efficient design limitations as specified checks
should be as follows:

deflection system, high voltage system, B+ system,2. Operate receiver for at least 15 minutes at 120V AC
test the X-Radiation protection circuit to ascertainline voltage, with a strong air signal or a properly tuned
proper operation as follows:in test signal.
3. Enter the service mode and select the service No.
1. Apply 120V AC using a variac transformer for"S21" and Bus data "01" (Y-mute on).
4. The voltage should be approximately, 32.8kV (at zero
accurate input voltage.beam).
2. Allow for warm up and adjust all customer controls
for normal picture and sound.If a correct reading cannot be obtained, check circuitry
3. Receive a good local channel.for malfunctioning components. After the voltage test,
make Y-mute off to the normal mode.
4. Connect a digital voltmeter to TP653 and make sure
that the voltmeter reads 11.83?0.7V (32L-S500,
CL32S50, 32L-X2000)/11.80?0.7V (36L-X2000).
5. Apply external 14.5V DC at TP653 by using an
external DC supply, TV must be shut off.
6. To reset the protector, unplug the AC cord and plug
the AC cord power on. 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.
