Failure in the DEFLECTION SERVICE Assy.
There are six main possibilities:
1. Blown fuse (s) in secondary
2. Abnormality in the regulator of heater
3. Overload detection
4. H. deflection stopping detection
5. X-ray protection
6. V. deflection stopping

oading

of

the CONVER. AMP

Check that waveform signals are output from pin 3 and pin 1
of the CN401, CN402 and CN403, and that the DC element is
not added to the signals.

IC401, IC402
(POWER SUPPLY Assy)

CONVER. MUTING not activated

Check that the electric potential of pin 3 and pin 4 of IC401
and IC402 are at the same level when the power is turned on.

Q404, Q402
(POWER SUPPLY Assy)

If the FU1001 and FU1002 fuses are blown, see the following table:

Note:

The anode of the diode is high only for a short time after the power is turned on until the protection circuits are activated (P.D.)
The LEDs are lit by the HOLD circuit.

Note that the power may be shut down when the voltages AC120V, 5V6 and STB5V from the POWER SUPPLY Assy are not
supplied because the DEFLECTION SERVICE Assy is powered by the POWER SUPPLY Assy.

When overload detection mechanism is activated, the 120 V line is short-circuited. If the power switch is set to ON again in this condition,
there may be a case where the power cannot be turned on, with just a whining sound, and where only the D111 LED in the POWER
SUPPLY Assy is lit. If this happens, disconnect the AC cord from the AC outlet or turn the main power switch OFF, and wait for five
minutes.

Be sure to check the fuses in the DEFLECTION SERVICE Assy because one or more may be blown as a result of short-circuiting of the
load circuit of the DEFLECTION SERVICE Assy.

Hi

Blown fuse (s)

The voltage (approx. 23V) at R831 is not supplied.
