WD-73727 Error Code 34 (Abnormal Lamp)

I just purchased a used Mit WD-73727 DLP TV. After setting it up and watching it for about an hour or so, the set turned itself off and the lamp LED came on red. Going thru the diagnostics, I got an error code 34. At this point I think the bulb just burned-out on me, but I resent the system and went to bed. The next morning, I try to turn the TV on. It starts up fine, no problems. Of course, I only had it on for 8-10 min 'cause I had to head to work.

Do you think it's the lamp? I was under the impression (maybe wrongly so) that once it was gone, it was gone.

I got a really good deal on the set and if I need to drop $200 on a lamp I'm still ahead. But if it's something major, I'd like to return the ASAP.

Thanks in Advance!

I have a 2 year old Mitsubishi Rear Projection 52" model WD-52525. I recently experienced the same problem as you. My TV quit without any warning and the red lamp light came on. I bought a replacement lamp just like you did, did everything you did too, but it still didn't work either. Since it's past the 1 yr warranty (of course), I took it in to an authorized service center for an estimate. They determined the light engine failed and it will cost me $816.35 to repair. I already shelled out $240+ for a lamp, $48 for the repair estimate and I said "hell" no, I'm not going to fix it for another $800+ and bought a new TV. I'm writing a letter to Mitsubishi expressing my deep dissatisfaction (to put it mildly) with this faulty product and will be requesting reimbursement, which I probably won't get. I sincerely hope this is not the same problem your TV has, but if it is be prepared for a costly fix.

There are a few things that could cause this. The lamp is the most common but I have seen some other werid thing cause this problem (ballast and engine) changing the lamp would be a good way to "shotgun" the repair but if you want to know for certain you will need to call someone out that can troubleshoot it the right way. Good luck and if you need any more information please let me know.

Thank You

My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


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.

TV turned off by itself one day. I pressed reset, timer light blinked green for a minute, then I pressed power and it sounded like it wanted to boot up, but nothing happened and the status light turn


Two thoughts:

First is this is a DLP set and the lamp may have failed

Second is it should have the self check which reads error codes---most of these sets that is the same:

" 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.
(then release both)

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
This is for a earlier Mitsubishi DLP but should be the same as your set as Mitsubishi rarely changes things like this.
If you get the lamp abnormal it is likely your problem.

I have a 57" mitsubishi


You probably have a bad lamp again I hate to say. These lamp are so critical when being moved. If after you atttempt to power on TV then red light shows, press menu+input on the front panel and hold for 5 seconds. Front timer LED will blink a 2 digit error code five times then stop. Code 34 and 66 are lamp errors, and if you read code 66 the lamp is broken. Good luck

Buzzing noise from Mitsubishi DLP WD-52327 after replacing bulb


Did your replace lamp come on the screen or did you lose picture? Just because the LED indicator suggest replace lamp it doesn't mean it needs it. If your pix was dull or loss of brightness then replace it, if not then just reset your lamp timer, check your owners manual for instructions.
