When it shuts off. Try doing what's called a self-diagnostic test. As soon as the television shuts try these steps.
Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds, activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem has occured since the last Initalization.
Please do 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. ? The Error Code is repeated a total of 5 times. Example: If the Error Code is ?24?, the LED will flash two times, pause, and then flash four times.
The Error Code designations indicating a malfunction, or no malfunction, are listed below: Self Diagnosic Code Description 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source).
Certainly, I can help you. I would recommend going to the following link and getting the service manual so you can see first hand disassembly instructions and testing procedures. Its only 10.99 and they email it to you shortly after purchase. The manual is a valuable resource as it will have part numbers in case you do need a new KD board. heres the link. http://servicemanuals.vstore.ca/
Could be convergence. Check the error code by pressing menu and device together for 5 sec and the timer light will flash a code. If it flashes 2 times pause and 2 times again it is the convergence IC stk393-110 and 2 fuses. Goodluck.
You can press the "DEVICE" and "MENU" keys on the front of the TV (not the remote) and the TV should flash an error code. Here is a chart.
Error Code Probable Cause
12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected
If the code is lets say 36 the LED will flash 3 times then pause then 6 flashes.
Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
Disconnect ALL devices from the TV.
Press the SYSTEM RESET button and hold for 10 seconds. Proceed if the problem still exist.
Press and hold POWER and MENU buttons simultaneously for 20 seconds. Proceed if the problem still exist.
Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours.
If it still shuts down, press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "35", the LED will flash 3 times, pauses, then flashes 5 times. The error code is repeated a total of 5 times.
Please let me know the code you got and I'll tell where the problem lies and how to fix it.
the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
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.
• The Error Code is repeated a total of 5 times.
and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure
