(1) BUS control data preset.
(2) When horizontal oscillation frequency is 15.75 kHz (00), measure the output pulse width TH00 of pin 13
(HD1-OUT) wave form.
(3) When horizontal oscillation frequency is 31.5 kHz (01), 33.75 kHz (10), 45 kHz (11), measure the output
pulse width TH01, TH02, TH03 as well.
HB04

OPEN
b
(1) BUS control data preset.
(2) SW6 open. When horizontal oscillation frequency is 15.75 kHz (00), measure the oscillation frequency F00 of
pin 13 (HD1-OUT) wave form.
(3) When horizontal oscillation frequency is 31.5 kHz (01), 33.75 kHz (10), 45 kHz (11), measure the oscillation
frequency F01, F10, F11 as well.
(4) When horizontal oscillation frequency is 15.75 kHz (00) and vertical free-run frequency is (101), measure the
oscillation frequency F50 of pin 15 wave form.
HB05
Horizontal oscillation control sensitivity OPEN
b
(1) BUS control data preset.
(2) SW6 open.
(3) Connect external voltage with pin 6 . Horizontal oscillation frequency is 15.75 kHz (00). Supply V6 (about 6.3
V)
+
0.05 V or V6
0.05 V to pin 6, then measure the frequency FA, FB of pin 13 (HD1-OUT) wave form.
Calculate frequency changing ratio (BH00). BH00
=
(FB
FA)/0.1
(4) When horizontal oscillation frequency is 31.5 kHz (01), 33.75 kHz (10), 45 kHz (11), calculate BH01, BH10,
BH11 as wall.
