PATTERN R, G and B become effective only when the monitor is started singly. Each can produce a solid
filled screen of 256-level gray scale, which can be used for IC wire connection checking when a certain gray
scale level is not produced.
Data bit dropout (gray-scale-related)
Set PATTERN1 on the adjustment
process menu to "2". Is the gray
scale pattern displayed correctly?
Check the color signal in question
with the gray scale test pattern. Is
there a problem with the contact
and resistance between IC4501
and SC4601-4604?
Check FFC
connected to
SC4601-4604.
Perform checking around
IC4501 and SC4601-4604.
Set PATTERN3 on the adjustment
process menu to "1" to "3" (the QS
drive test pattern is displayed). Is
the gray scale displayed correctly?
Perform checking around
IC4702 and IC4902.
Perform checking between
IC4701 and IC4501.
Perform checking between
IC4901 and IC4501.
Set PATTERN3 on the adjustment
process menu to "4". Is the test
pattern displayed correctly at
intervals of one dot?
Set PATTERN3 on the adjustment
process menu to "5". Is the test
pattern displayed correctly at
intervals of one dot?
Perform checking between SC2201
and IC2206, between IC2206 and
IC4701 or between IC2206 and
IC4901.

No picture comes out.
Is the RSET terminal (pin (3))
of IC2206 set to "H"?
Perform checking around X2201
connected to pin (161) of IC2206.
Is X2201 connected to pin (161) of
IC2206 oscillating (18.26 MHz)?
Is IC2202 operating (CONFIG
ROM)?
Perform checking
around IC2202.
Check X2201 and the
peripheral circuitry.
Is the clock (91.3 MHz) applied to
TL2202 (pin (102) of IC2206)?
Is the normal synchronization
signal is applied to TL2202 (pin
(97) of IC2206), TL2203 (pin
(96) of IC2206) and TL2204
(pin (95) of IC2206)?
YES
YES
IC2206 is faulty.
Check IC4903 and the ICs
(IC4701, IC4702, IC4901 and
IC4902) downstream from it.
Note that the unit should be replaced when the receiver IC (IC2206), HDCP key ROM (IC2208) or microprocessor
(IC2004) is replaced.
