Marantz 12s3 Problem (1 Viewer)

[billN]

I've had a Marantz 12S3 projector for about 4 months now and it's been performing great until recently. It seems that after about an hour of use, every few minutes the brightness will change slightly - either brighter or darker. The change is subtle but annoying. Once in a while it actually flickers a bit before settling down. Is this a sign of a defective lamp/bulb? The lamp only has about 150 hours on it - so I'm a little confused. If it's not the lamp, does anyone have any idea what the problem could be?
I actually purchased the projector from EBAY. I got a great deal - but no warranty. I'm keeping my fingers crossed I don't regret doing that. Any help would be appreciated!!!!
