SUMMARY OF SELF-DIAGNOSIS FUNCTION
* This device includes a self-diagnosis function.
* In case of abnormalities, the TIMER/STANDBY indicator automatically blinks. It is possible to predict the abnormality location by the number of blinks. The Instruction Manual describes blinking of the TIMER/STANDBY indicator.
* If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was generated or not. Operate the remote command to confirm the matter on the screen and to predict the location of the abnormality.

FRONT LED INDICATOR DIAGNOSIS
The front panel LEDs provide an indication of the sets operation, and the possible cause of a malfunction. There are three front panel LEDs, “Power”, “Status” and “Lamp”. Which LED is lit, the colour, and whether it is blinking or steady indicate the current status, or a possible malfunction.
Error Code Operational Check
Note: The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control. • The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

* The flashing then pauses for approximately 1/2 second.
* The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.

This device includes a self-diagnosis function.
In case of abnormalities, the POWER/STANDBY indicator automatically blinks. It is possible to predict the abnormality location by the number of blinks. The Instruction Manual describes blinking of the POWER/STANDBY indicator.
If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was generated or not. Operate the remote command to confirm the matter on the screen and to predict the location of the abnormality.

Diagnosis Items and Prediction of Malfunction Location
When a malfunction occurs the POWER/STANDBY indicator only blinks for one of the following diagnosis items. In case of two or more malfunctions, the item which first occurred blinks. If the malfunctions occurred simultaneously, 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 malfunctions occurred.

The results display is not automatically cleared. In case of repairs and after repairs, check the self-diagnosis screen and be sure to return the results display to "0".
If the results display is not returned to "0" it will not be possible to judge a new malfunction after completing repairs.

2) Temp >> When the temperature sensor (for Ambient) on the S1 board detects high temperature or the temperature sensor (for Lamp) on the S2 board detects high temperature or the temperature sensor (for Panel) on the C board detects high temperature, the DE-micro (IC5) turns off the lamp.
3) Lamp cover >> The rib at the back of the lamp cover closes the SW on the T1 board. The lamp closes the SW on the T2 board. It is monitored by DE-micro (pin63 of IC5) and turned off the lamp when it is opened.
4) Fan >> Fan rotation is detected by ‘‘FAN-PROT” and the DE-micro (pin92 of IC5) turns off the lamp when it is ‘‘high”.
5) Lamp Driver >> When the ‘‘LAMP-PROT” (pin83 of IC5) is high, the lamp is not turned on. If the ‘‘LAMP-HV-DET” (pin94 of IC5) is low at the same time, it classified as no high voltage of the lamp driver.
6) Low B error >> When no ‘‘D5V (SW_5V)” is detected, pin 129 of TV-micro (IC7002) is low and it turns off the main power. (for example, blowout of thermal fuse).
7) Audio >> When DC voltage is detected at the speaker output, ‘‘SP-PROT” (pin102 of IC5) is low and it turns off the main power.
8) D-OVP >> Be not in use.
9) Panel error >> When there is no track from the temperature sensor on the S1, S2 and C board or IIC line connector (CN2303: ASU board, CN7956: DSU board, CN6901: C board) is not seated securely. It is monitored by DE-micro.
10) ATSC-OVP >> Be not in use.
(LAMP) - Lamp >> When the ‘‘LAMP-PROT” (pin83 of IC5) is high, the lamp is not turned on. If the ‘‘LAMP-HV-DET” (pin94 of IC5) is high at the same time, it classified as no lamp or a dead lamp.

SPECS:
The identification of errors is triggered in one of two ways.
TV System B / G / H,D / K,I,L
Colour System
PAL, SECAM \NTSC3.58, 4.43 (Video IN only)
Channel Coverage
VHF > E2 ~ E12
UHF > E21~E69
CATV >S1~S20
HYPER > S21~S41
D /K > R-1~R12, R11~R69
I > UHF B21~B69
L > F2~F10, B-Q, F21~F69The identification of errors is triggered in one of two ways.
1) Busy or
2) Device failure to respond to IIC. In the event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with continuous flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number will be displayed through the LED (Series of flashes which must be counted) , non fatal errors are reported using this method.
BLINKING CODES
ERROR DETECTION MONITOR
Device acknowledges is used to check IIC errors. Each device is checked three times, if there is no acknowledge after every attempt, it will be regarded as an error. There are three step to check errors.
IIC line 0: If all devices except the NVM have errors, IIC line 0 errors are displayed.
Each device check: if IIC line error and board error are not detected then the device with an error is displayed.
Each device check: if IIC line error and board error are not detected then the device with an error is displayed.
