Replaced Lamp TV shuts down still?

I’m having a problem with my Mitsubishi Lamp replacement, I did a replacement for the Lamp and it went completely smooth nothing broken just the lamp. I did a hard reset and when the tv turns on it stays on for about 30-40 seconds and then shuts down. The Tv also provides me with the 34 error code that the Lamp is bad but I had just replaced it, not also did I replaced it but I cleaned out the dust using an air can and is as clean as could be. Very confused, any ideas??
