COMMON FAULTS

• When the domestic Power LED indicator does not light up => 
• Check whether or not the power cord is connected.
• Check whether the power switch on the right side of the set has been pressed.
• Check the Line Filter Fuse.
• Check connectors of the analog [CN111 & CN511] connectors.
• Check the connection of the Digital CN307 connector and check whether the LED indicator OP301 (one) is lit.
• Check the connection of Digital CN303 connector and check whether [5V] power has been supplied to Pin-5.

=======================================================================

• When the abnormal Temperature Indicator LED is lit or flickers => 
• Check whether the temperature sensor connector attached to the engine has been inserted normally into CN305 on the Digital Board.
• Check whether the temperature sensor is normal when both terminals has been short circuited: (connected).

=======================================================================

Timer + Standby LED blinking at abnormal temperature.  Power LED blinking at abnormal temperature => 

• Check that the fan operates when LED for timer, standby or abnormal temperature blinks.
• Check that the cover detection switch is inserted at CN310 on Digital board when LED for timer, standby or abnormal temperature blinks.

When the timer lamp and Abnormal Temperature LED indicators flicker simultaneously =>

• If the 3 LED indicators flicker from the time the set is turned ON >
• The CN106 connector on the DMD board is not inserted properly. 
• The MDR cable that connects the Digital board to the DMD board is not connected properly.

---------------------------------------------------------------------------------------------------------------

• If the lamp does not turn on even after turning it on 3 times, by power Off/On 15 seconds intervals >
• The +B 380V power is not supplied to the ballast.  Check whether the cable is not connected properly between the power and the ballast.
• The cable connected to the CN110 terminal on the DMD board and the CN2 terminal of the ballast short circuited or not properly connected.
• The lamp does not turn On because (5V) has not been supplied to the blue pin #1 on the CN2 terminal of the ballast.
• 5V is supplied to the CN2 terminal on the ballast, but the lamp does not turn On because of the ballast has a failure.  If the lamp is replaced and (5V) is supplied normally to the CN@ terminal  suspect the 'ballast failure' if lamp still does not turn On.
• The ballast is normal but the lamp does not turn On, even when the 5V is supplied normally to the CN2 terminal, and 385V to CN1, try replacing the lamp.  If it turns On means that the lamp is faulty.
• The color wheel engaged to engine does not operate or the connector which indicates the operation of the color wheel is not connected properly, and there fore does not allow the lamp to turn On.  The cause can be determined when the set still does not turn On after attempting to turn it On three times.
• Another digital board or DMD board has a failure.   Conclusively, if the three LED indicators flicker, first check the above items, then check the various connector connections, and then suspect a failure of  the lamp or the ballast.

----------------------------------------------------------------------------------------------------------------------

If the set is normal => 

• Means that the lamp is turned On normally.  Description of LED  indicator operations >

1. The lamp LED indicator flickers while turning On the lamp.
2. The mechanism is designed in such a way that if three turning-on trials; within 15 seconds of intervals between each trial; fail,  the set should be Powered Off, and then three turning-On trials should be tried again.

--------------------------------------------------------------------------------------------------------------------

Failure Name:  Failure if LED indicators are normal, but the screen is not displayed.

• Check whether the external LED indicator of the set is normal.  Only the Lamp Indicator should be turned On.
• Check whether the digital board LED indicators inside the set are lit:  All of the three LED indicators should be turned On.  Can observe those LED indicators through the cabinet holes at the back of the set.  All three LED indicators should be turned On.
• Check whether the set Lamp is turned On:  When the lamp is turned Off, replace it.  When turn On the set again after replacing the lamp, it should turn On within 30 seconds; for 50 and 61 inch TVs.  If more than one minute passes before it turns On, or it does not turn On, replace both ballast withing the engine and Lamp together.  

--------------------------------------------------------------------------------------------------------------------

Lamp replacement:  

1. Remove the lamp cover screw.
2. Remove the screws on both sides of the lamp.
3. Pull the lamp out by holding its knob, and then replace it with a new one.
4. Replace lamp cover and dcrew it firmly.

Ballast Operation Check:  

1. Open the back cover of the set, and short the protection switch. 
2. Check whether the Power and Lamp Enable signal have been supplied ot the Ballast.  
3. Check whether 5V is supplied to the Blue terminal of CN2.
4. Check whether DC380V is supplied to both end terminals of CN2.
5. If 5V is applied to the CN2 terminals of the ballast, but the lamp does not turn On, 'replace the ballast'.
6. When the 5V is not supplied, replace the first engine.  If the lamp still does not work, 'replace DMD' board attached to the engine

The Lamp is normal, but a blank screen failure occurs >

• Check the signal supply procedure.  Check whether the signals are supplied from the analog board to the digital board.  
• Check in which mode the screen does not display.
• If the RF, VIDEO, DVD or DTV mode screen does not display, check the analog CN511 terminals, Digital CN309 connector connections, and their signaling 
• The DVI or PC mode does not display, replace and inspect the digital board.
• If the screen does not display in any mode, check whether the signals are being output from the digital baord.
• Check the output of the IC314 terminal.  If the signal output state is normal, suspect DMD board.  
• Check whether  +26V and -26V is being supplied to DMD board.  If the voltage is normal, replace the 'tantal' condenser (C116, C110 when failure occurs intermittently.)  If the problem continues after replacement, then replace the power drive IC [IC108].
• If the DMD voltage is normal, replace the panel, or reassemble the panel.  [Try to fix the four silver screws again]

DMD state inspection Method >

• Remove the heat sink attached to DMD board.  
• Fix the DMD by  tightening the screw again. 
• Check the signaling for each point.
• If the horizontal raster failure occurs; 
• Check whether the output of the R NETWORK (RA101 TO RA104) terminals of DMD board are normal.
• If vertical line failure occurs; 
• Check whether it occurs within the regular wide range. (Less than 26mm for 50" TV)
• If it appears at regular intervals of less than 26mm, check the DMD fixing state.  Loosen the four silver screws, and then re-assemble them.
• If the vertical lines do not occur at regular intervals, or intervals are more than 26mm, or irregular, replace IC117 (DDP1010).
