ADJUSTMENT C ONDITION / PROCEDURE
(1) Make sure the following items are in INITIAL
DATA before adjust CR T cutoff
(a) 15 DRI-RS = 32
(b) 16 DRI-GS = 32
(c) 17 DRI-BS = 32
(d) 18 CUT -RS = 16
(e) 19 CUT -GS = 16
(f) 20 CUT -BS = 16
(f) 21 SUB BRI = 24
(g) 22 SUB CON = 59
(h) 32 CUT OFF = 25
(i) 35 BLOC= 4
(2) Switch TV to video mode, blue back off, with
no signal and press R/C to set picture into
normal condition.
(3) G o to service mode, select item 31 VSD
(dark screen display)
(4) Adjust the Screen so that cut-off line appear in
low bright, then judge that whether the cut-off
line appear in Red or Green or Blue color, in
this condition between CUT -RS & C UT -GS &
cut-BS, fix the data of the color appear in
cut-off line and adj the other two cut-off data
(Note 1) so that cut-off line color become white.
(5) Turn the screen VR of FBT s o that cut-off line
just disappear
(1) WHITE (HIGH BEAM)
(In Window Pattern Signal)
First use Minolta Color Analyzer CA100, let the
gun point at Dark White position (as drawing
attach), Adj SUB-BRI until LUMINANCE Y
become 4 cd/m2 , then let the gun point at
White position (as drawing attach), Adj SUB-
CON until LUMINANCE Y become: 150 cd/m2.
Adj the DRI-RS & DRI-BS until the axis of color
temperature become
12300 K X : 0.272 , Y : 0.275
(2) DARK WHITE (LOW BEAM)
Let the gun point at Dark White position, if
the color temperature data shift away from
the data adjusted in Item 1 Screen
adjustment, adjust CUT -RS, CUT GS
& C UT -BS.
Please fix the first colour appears in Screen
adj item step (4) is fixed, adj the other two
so that to obtain the similar axis as above.
