Replaced lamp on WD57731. green light turns on
Please put back lamp cover, the last plastic grille that were removed to replace lamp in TV.
TV sense that lamp cover is not either put back or not fixed properly so it wont turn On. Check lamp cover and problem will be solved.
Thanks.

Error / problem message
these are on mitsubishi's recall list you need to get in touch with mitsubishi and have them find a authorized servicer in your area to come put a thermal sensor in your set.
How do I remove the lamp door
there are 2 phillips head screws on the door remove them and the door comes off. Look up inside and you can see the lamp it has either 2 or 3 screws in it. You loosen them all the way off but they do not come out of the housing. Grab the handle and pull the lamp out.
How much for a new screen?
Well you will need to donate more than 2 arms and 2 legs may be cheaper to buy a second hand unit complete
The screen is delaminating at the bottom. can the
Yes the screen can be replaced but is very expensive.There is also a service bulletin on this chassis for replacing an overheat sensor behind the lamp assembly. The overheat message will appear on the screen.
Dead lamp
The sensor is located on or near the lamp compartment on the back side. If your lamp keeps blowing it may be the lamp cooling fan not working. However are you sure the lamp is blowing? Press menu and device on the front control panel both in together for 5 seconds and see if the led blinks a two digit code, then let me know the code. Please respond to this same post.

I'm assuming that you already have the housing out of the TV. If not remove the lamp cover panel (two phillips screws), Locate and unscrew the two chromed flat blade screws that hold the module in place and gently pull the housing out. Now locate the three locking tabs on the housing. There is a large one on the bulb face side, and two smaller ones on the mesh screen side near the handle end. Using a thin bladed screw driver, slide it under the curved edge next to each of the small tabs and gently pry up to pop the side cover off of the tabs. Rotate the back cover (three sided) so that the small tabs come clear of the rectangular holes in the cover. (It should pivot on the third tab). Now use the screw driver to gently pry the U shaped clip off and over the third tab. Once all three tabs have been released the back half should just slide back and off the front half. Reassembly is basically just sliding the back cover back on until the tabs lock into place. While the bulb is out blow all the dust out of all THREE screens (there is a small one next to the greyish metal plate).
Replace the bulb by removing all the internal screws necessary to release it from the housing, noting how everything goes back together, including which wire goes to which terminal (If your bulb does not come with new wires you'll have to swap them to the new bulb), and where the "UP" marking on the bulb goes. Drawing a picture or better yet taking a few pictures is a good idea. When installing the new bulb do not touch the bulb with your bare hands (use latex gloves). Supposedly the skin oils can cause the bulb to fail prematurely. Finally make sure that the wires do not touch the bulb and are as far away from it as possible after it is back together, if necessary open it back up and bend the wires to reposition them.

SCREEN IS BLACK
Called a service tech, (for free)
he said it was probably the lamp, and it was an easy fix.
Just have to order the lamp and put it in our selves.
I will let you know if it works or not.
We were told the lamp goes out anywhere between 1000 - 2000 hours.
So we will be needing the lamp regardless.
I have a wd 57732
Hi! It's perfectly safe! Just be sure to always wait an hour or preferebly more before doing this, and unplug the tv! On a DLP tv such as this there is a hatch with two phillips screws holding the cover on for the bulb assembly. Remove them 2 screws. Remove the cover and you will see two thumbscrews that may need extra help from a screwdiver as they may be too tight. Now put on a pair of vinyl or rubber gloves and pull the lamp cartridge absolutly straight out with no twist motion!. Glass lamp section will potentially fall if you do. Place the cartridge on a flat surface and find the 3 tabs on the lamp unit and carefully pry them off. Inside, take out the 4 screws and the mounting brackets holding bulb. At this point you can clean out dust inside the lamp box. Next take out the old bulb, put the new one in (be sure to use the gloves installing new bulb or else any finger oil will cause the bulb to fail when it gets hot) and reverse steps to close.

Trouble turning on
Try pushing the Imput and Menu buttons in together on the set and hold for 5 minutes and see if it blinks out a two digit code. Then let me know. Also these sets have a tendency to have some faulty capacitors on the DM board. Hope this helps youout.
