Measurement methods
(1) Input a composite sync signal into Pin61.
(2) Changing BUS data of “Horizontal Position” from 0 to 31,
measure "

(3) Measure the H phase where the pin #73 (Hcorr) is opened
and the HPOS is 16
(4) Measure the H phase shift form (3) when supply 5.5V for
pin #73, that is
ΔＰＨ

(5) Measure the H phase shift from (3) when supply 0.5V for
pin #73, that is

(1) Input a composite sync signal into Pin61.
(2) Decreasing the FBP high level, measure the DC level at
which H OUT phase changes against Sync in(Pin61)
phase, that is "V
AFC2
".
(1) Input a composite sync signal into Pin61.
(2) Increasing the FBP high level, measure the DC level at
which H blanking begins to work, that is "V
HBLK
".
(3) Measure as the figure below when the IICBUS of
'W-HBLK=1' and when input 50/60Hz of V freq.
