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/input" 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.

4. Error Codes

The Error Code designations are listed below:

Error Code Probable Cause

12 No error detected

22 Recovery from momentary Reset

32 Lamp Cover open

33 Air Filter Cover open

34 Lamp abnormalities

35 Chassis Fan failures

36 Exhaust (Back Cover) or Lamp Ballast Fan failure

37 Engine (DMD or Lamp) Fan failure

38 Excess Lamp Temperatures

39 Excess DMD Temperatures

41 Short Detected

44 DVI Cable (between Chassis and Engine) disconnected

do you know where i can find a free dowload of the service manual? ive also been reading about a bad connection at the thermistor

Expert:  Rick williams replied 7 years ago.
A service manual isn't free from any place, I wish, well the fans that cool it can be dirty, so lets not make this more than it is, and what your referring to is a thermistor that goes bad and on screen will say airflow block this isn't your issue, you just need to clean and order a new Lamp, Thats all friend.
