Wd-y577 error code 3 4 - Mitsubishi WD-Y577 Television

Caveat: I am not a tech, I just read through the Mitsubishi service manual, and have worked on different model TV that I have owned (older model of this one) I am a little unclear on the second set of lights but I think the combination *may* indicate that the lamp fan is not starting (there are two fans though), if the blinking red is the status light. It is possible the connector for that got jostled during the trip, something fell into it from being on the side (wire or loose something) and is blocking it from spinning now, or a module unseated a bit,and is loose, or the lamp is no longer seated correctly (though the lamp light does not appear to be on) or none of these. :) These are just guesses.
Be careful if you open it up, due to potential for shock. Wear gloves, and power it down first (then unplug). Reseat any fan connectors.

Google: I used "wd-65735 status lights" to find a service pdf , it's for V39 chassis (several models)

From page 24 of Service Manual :

3. Error Code Operational Check Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Opera- tional Check. When the TV is switched Off, the code automatically resets to "12" No Error.
Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds, activates the Error Code Mode. The "TIMER LED" flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must be used, NOT those on the Remote Control.

Double check as no 42 is indicated on their site.

Hi, Your problem has to be a defect in the optical engine. Cost of replacing this unit can run from $800 to $1200. Call Mits at 800-332-2119 with model, serial and date of purchase. They should be willing to help. Thx

Your DLP chip is failing. The tiny micro mirrors within this chip are stuck. More white dots will appear over time until it looks like a star field on your screen. Most places will tell you that you need a new light engine, however you can replace the DLP chip itself and it will take you about 30 mins. You can find the chip online for around $349 but I think I have DLP chip you need brand new for $225. If you are interested in this contact me. [email protected]

THE PROBLEM CAN BE CORRECTED BY REPLACING LAMP WITH THE ORIGINAL LAMP FROM MITSUBISHI CHECK THE ORIGINAL LAMP HAS A MAGNAFIER ON TOP OF THE LAMP.

U check the tv Ballast board?This board it is to help the projection lamp to ignite.

CK the Lamp Fan if it stops running when Lamp starts to light set will shut off.
Ballast board is what powers Lamp on.

Yes... from the moment the lamp is put into service, it begins to deminish in brightness. You should order a replacement lamp to have on hand.

That code can often be caused by failed capacitors on the power board which will cause the 34 error for lamp abnormality. The V26 Power repair kit at www.tvrepairworld.com may fix that issue. The kit contains the replacement capacitors and has the CD with instructions.
