Epson 3lCD Projector - smartboard wobble

[kirstycc]

Hi

 

I have an Epson projector in my class and recently had to replace the lamp (ELPLP41). It worked fine the first day and since then the projection onto my smartboard intermittently (mostly but not consistently) wobbles from side to side like someone is jumping on the projector. No changes have been made to anything else in the classroom.

 

Any ideas what might be causing the wobble? I've removed and refitted the lamp but the problem persists.

 

Many thanks.

Might be a faulty lamp. Have you tried swapping the lamp with another one in the school which is working well, obviously needs to be the same projector
