6. SELF DIAGNOSTIC FUNCTION
1) Press "9" button on Remote Control during display of adjustment menu in the service mode.
The diagnosis will begin to check if interface among IC's are executed properly.
2) During diagnosis, the following displays are shown.
SELF CHECK
NO. 23 * * * * * *
POWER
: 000
BUS LINE : OK
BUS CONT : OK
BLOCK : MAIN SUB
SET ID : 01
EEP VER : 02
OPT1 : 05
OPT2 : 70
Part number of microprocessor (QA01)
Operation number of protection circuit (current limiter) . . . . "000" is normal.
BUS line check
"OK" ................... Normal
"SCL-GND" or "NG" ........... SCL-GND short circuit
"SDA-GND" or "NG" ........... SDA-GND short circuit
"SCL-SDA" or "NG" ............ SCL-SDA short circuit
BUS line ACK (acknowledge) check
"OK" ................... Normal
Display of Location Number . . . . NG
(Display example)
"QA02 NG", "H001 NG", "Q501 NG" etc.
Note: The indication of failure place is only one place though failure places are plural. When
Sync. signal check
Green display ..... Normal
Red display ........ NG
ID code for TV Set
Version of "EEP"
Data for "OPT"
Part number of DVI microprocessor
DVI error code
01: SCDT error
02: THS8200 error
FF: DVI microprocessor error
TV set on time (hour)
LAMP on time (hour)
LAMP exchange time
7. Power control and current limiter detection (self diagnosis)
7-1 Power control
1) During STANBY: Set the POWER terminal (Pin15) to "L".
LED terminal (Pin 16)
2) During SET ON: Set the POWER terminal to Hi-z (input mode).
Set the LED terminal to "H".
7-2 Current limiter detection
1) When "L" is detected for 2 seconds or more after monitoring the POWER terminal during SET ON, it is jugded that the
current limiter is operated.
2) Turn ON/OFF the LED terminal every 0.5 second.
3) Make increment for the number of the current limiter detection times during "SELF CHECK".
DVI
NO
23009238
ERR CODE : 03
TIME : 000 268
LAMP :
0 268 00
repair of a failure place finishes, the next failure place is indicated. (The order of priority of
indication is left side.)
MAIN ........ Main sync
SUB .......... Sub sync (when turn on the PIP)
