DMD error code

What is the error code E8 on Voltas cassette AC unit?

An E8 error usually indicates a fan problem with the indoor or outdoor unit. An E8 error is usually cleared by power cycling both the indoor and outdoor unit by turning power off at the breaker. Be sure to check the indoor air filters are not dirty and blocking air flow from the fan.

..

According to the manual this means the Lamp cover door is open or lamp cartridge is not secure.

See Appendix F for lamp replacement information.

It is helpful to have the sequence of the blinking red light. This may help:

MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



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 "23", the LED will flash two times, pause, and then flash three times.

Hi,

Here is a whole list for you :

Mitsubishi Blinking Codes :

Constant Green - TV is Powered On
Constant Red - Lamp Failure
Constant Yellow - DMD temp is very high
Blinking Yellow - Lamp cover is open
1 Red Blink, 6 Yellow Blinks - Color Wheel Failure
3 Red Blinks, 4 Yellow Blinks - Lamp Failure
3 Red Blinks, 6 Yellow Blinks - Exhaust Fan Not Working
3 Red Blinks, 7 Yellow Blinks - DMD Fan is not rotating
5 Red Blinks, 7 Yellow Blinks - Ballast Problem
6 Red Blinks, 6 Yellow Blinks - Lamp Missing, Bad Cable between lamp and ballast

And the Lamp cover must be here somewhere in your TV :

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

error code 37 is either the dmd fan or the lamp fan. you can see the dmd fan with the cover off. you cannot set the lamp fan as it is under the light engine. I guess the easiest thing to do is get a lamp fan 299P282010 and a dmd fan 299P283010 and change them both.

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

After the lights on the front of the tv settle down, push and hold the menu and input (or deivice) buttons for 5 seconds. Now count the number of times the LED blinks and follow these instructions.
Cause #1 1. Self-diagnosis error 4-4, check for proper seating of the DVI cable between the FMT PCB and the DMD (Light Engine). It may be necessary to disconnect and reconnect this cable to insure proper connection. 2. Self-diagnosis error 4-4, check for 3.3 volts DC at connector J-9 pin 8 on the Engine Driver PCB, if missing check F9A06 part # 283P128050 on the Power PCB if this is open suspect the 3.3v regulator circuit on the Power PCB part # 930B921002 3. Self-diagnosis error 4-4, check for 3.3 volts DC at connector J-9 pin 8 on the Engine Driver PCB, if missing check F9A07 part # 283P128050 on the Power PCB, if open suspect it to have been opened by the Light Engine part # 939P977020 4. Self-diagnosis error 4-4, if the 3.3 volt supply at J-9 pin 8 is good and the connection on the DVI cable between the FMT PCB and DMD are secure, suspect the Light Engine part # 939P977020 5. Self-diagnosis error 4-1, suspect the Power PCB part # 930B921002

I found this list of codes
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

cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
