A simple way to maybe know is Google each model number with "lamp" and unless the replacement being sold is exactly the same number they will not work for each other.
Double check when lamp went in it engaged the socket (2 pin) correctly and went all the way in----this is where to begin-------whenever you replace a part on a TV or a car etc and suddenly have a new issue suspect something happened when you replaced that part........
yes, on the back of the tv is door, open it remove the lamp, do not touch the lamp itself. go online put in the model number of your tv and search for lamps, now make sure when purchasing you order the entire lamp assembly. this is real easy and will save you a ton of money doing it yourself
Looking at the back of the TV the lamp door is on the bottom left. Loosen the one screw holding it on. Remove the lamp door. Inside is the lamp unit. Loosen the two screws on the left of the lamp unit. Grab the handle on the lamp unit and pull it straight out. You may want to vacuum the dust (and glass) off at this point. Slide the new lamp unit straight into TV until it's fully seated. Tighten the two screws on the lamp unit. Re-install the door and tighten the screw. Lightweight gloves are recommended for this procedure.
I don't know your set in particular, therefore I will be generic.
On some projection sets, there is an hours counter that is manualy resetable. Make sure that it is reset. If you can have a readout of the amount of hours used on the lamp this will tell you if this needs to be reset.
Normaly, when the set reacts as per your description, there is a cooling problem, or a fault in the power supply.
Also with your model of set, check to see if there are any safety switches that work with the cover or door for the lamp access. With the safety switch option, if the uPC thinks that the lamp is not properly enclosed or installed it will not allow for proper startup.
Mitsubishi TV troubleshooting 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
