SECTION 1
SELF DIAGNOSIS FUNCTION
I. Summary of Self-Diagnosis Function
*
This device includes a self-diagnosis function.
In case of abnom~alities.the'oindicatorautomatically blinks. It is possible to predict the abnormality location by the number
of blinks. The Instruction Manual describes bhlking of themindicator.
*
If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was gener-
ated or not. Operate the remote command to confinn the matter on the screen
and to predlct the loc'lt~on of the abnormd~t>.
2. Diagnosis Items and Prediction of Malfunction Location
When a malfunction occurs thenindicator only blinks for one of the following diagnosis items. In case of two or more
malfunctions, the item uhch iirst occurred blinks. If the malfunctions occurred simultancously. the item with the lower blink
count blinks first.
The screen display displays the results regarding
all the diagnosis items listed below. The display " 0 " means that no malfunc-
tions occurred.

The STAYD BY indicator blinhgdisplay is released by turning OFF the power switch
on the
TV main unit or removing the plug from [he power.
But in the RLJY ERR (10 times blinhg). do not release by tuning power off.
For details. refer to the item 1-6.
4. Self-diagnosis screen displays
In cases of malfunctions where it is not possible to determine the symptom such as when the power goes off occasionally or when
thc screen disappears occasionally, there is a screen display on whether the malfunction occurred or not in the past (and whether
the detection circuit operated or not) in order to allow confirmation.
<Screen DisplayMethod>
Quickly press the remote command button in the following order from the standby state
Be aware that
this differs from the method of
entering the service mode ( r/1+/ )
Self-diagnosis screen display
"G" : OK, "NG" : DETECTS ONCE OR MORE
THE
10 DIGITS OF NUMERALS ARE FOR CHECKING,

101 : NO LED BLINKING FOR WDT.
"0" : NUMBER OF DETECTION.

5. After the self-diagnosis operation
.
The results &splay is not automatically cleared. In case of repairs and after repairs. check the self-diagnosisscreen and be sure
to return the results display to
" O ".
.
If the results display is not returned to '' 0 " it will not be possible to judge a new malfunctio~lafter completing repairs.

If the ICY01 Pin 11 (+B OCP DET) is hgh 2 seconds, turn AC-REl.AY low (P-OFF)and make STAVDBY

If the IC701 Pin
15 (+B OVI' DET) is high 2 seconds. turn AC-FGLAY low (P-OFF) and make STANDBY
LED blinks three times.
If the return data Bit0 (VNG) from CXA2150Q is "1" while 2 seconds. turn AC-RELAY low (P-OFF) and
inakc STANDBY LED blinks four times.
If the return data Bit2 (IKREF) Erom CXA2
1SOQ is "0" and there is no chanze for 20 seconds, make
ST.4,XDBY LED blinks five times.
At this time, AC-RELAY continues to high.
If the
IC701 Pin 69 (AC-RELAY) is high and the Pin 43 (LOW-B ERfiOR DET) is low while 5 seconds.
turn AC-RELAY low (P-OFF)and make STANDBY LED blinks six times.
If the return data Bit1
(HNG) from CX42170 is "1" while 2 seconds, turn AC-RELAY low (P-OFF)md
make STANDBYLED blinks seven times.
Obsenies the watch dock timer (BUS COMMLWIC!iTION ERROR DET)bus communication. If errors are
detected, counts up and reform the bus communication and displays the number of

(No LED blinking).
In case of Pin 85 of ICSOl (AUDIO PROT DET) turns high 60msec twice at a time. makes AC-RELAY
turns low (Poweroff) and STANDBY-LED blink
8 rimes.
In case of Pin 33 of IClOl (HV-PROT DET) Lurns high 10 seconds conrinuously in normal operation or in
BS fixed Stand-by, makes AC-RELAY turns low (Power off) and ST,L\NDBY-LED blinks 10 times.
There are two causes for Zero Cross Error.
?Jormally the pulse doubledAC power supply frequeny is fed to Pin 8 of ICIOS. But in case of the
abnormal pulse is fed.
it makes AC-RELAY turns low (Power offj and STAYDBY-LED blinks 9
times.
Jii this case, "1" is nor displayed in '9. Z DET' column in the self-diagnosis mode.

HOW TO HANDLE AN ANODE-CAP
@ Do not damage the surface of anode-capswith sharp shaped objects.
@ Do not pressthe rubber too hard soas notto damage the inside of anode-cap.
A metalfitting called the shatter-hook terminal is built into the rubber.
@ Do not turn the foot of rubber over too hard.
The shatter-hook terminal will stick out or damage the rubber.
