    I had exactly the same problem. Followed the instructions to reset the overheat switch which had tripped. Now working.

I had this issue.  Turned out the thermal switch was tripped and just needed to be reset. (The usual disclaimer: This procedure will void your warranty and is entirely at your own risk) Remove the six screws marked with arrows to open the top (be careful as there are still wires connecting the top to the bottom.  The thermal switch is directly over the bulb assembly and connects to the main board with two thin wires (grey and white on my Z4).  You can check the switch with a multi-meter.  Normally the two wires should be shorted, if there's no continuity it's tripped.  When it trips a small plastic pin painted white on top pops up, just press it back down and you should be good to go.  (It's a good idea to clean your filters, and check the projector ventilation after to ensure it doesn't get tripped again)

Dell 3200mp lamp

are both of the lamps the same? have you installed it correctly in the socket. you might need to do a cold start for your projector. unlpugg it and try to wait for 5 minutes before plugging it again and turning it on. one your projector detected that a new lamp is intalled, it should work fine now. but if its still not working, you might want to try and replace the new lamp again. sometimes this happens.

hope this helps.

Our projector indicates that the light bulb needs to be replaced after replacing the light bulb once it still indicates that it needs to be replaced.

This is the excerpt from the manual on how to reset the lamp life timer.

Turn on the projector and use "Lamp Reset" after the lamp module is replaced.
Lamp Reset: (i) Press "Menu" ?§ (ii) Select "Options" ?§ (iii) Select "Lamp settings" ?§ (iv) Select "Lamp Reset ?§ (v) Select "Yes".

Projector does not turn ON

try removing the lamp, usually quite easy, you need to find the door for the lamp. lamps are customer replaceable, usually. If the lamp is bad you can usually see it damaged in the lamp. kind of like you might be able to see the broken filament in your normale house hold light bulb. good luck.
