I am hoping I can get a little insight from the people here. I have just recently noticed my AE900 is showing a green line at the bottom of the screen that goes across the whole bottom of the screen. On 1.78:1 images it shows at the very bottom of the screen and on movies that are 2.35:1 (for example), the line shows just above the black bar created by the different aspect ratio. I get this on sources connected using both component cable (Xbox 360, DirecTV) AND with HDMI sources (PS3, Toshiba A2 - HD-DVD).

Not knowing exactly what causes this, I tried a couple of things. I currently run my sources thru my receiver, so I tried a direct connection from the source and from a switcher and got the same results regardless of the connection. It also is the same with overscan on and off.

I don't know much about the insides of these things and what causes these problems, so hopefully one of you will know. My few questions are:
1. What is problem?
2. Can it be fixed?
3. I bought the projector on 4/12/2006 and am still in the 1 year warranty, would this typically be covered by warranty?

My unit has about 800 hours on it so far and I have run it in low lamp all the time.

Pictures:The full screen might not show it very clearly but the close up is of the bottom of the Xbox 360 screen and hopefully you can clearly see the green line.

Thanks in advance for any help! This sight is what led me to buy the projector in the first place.


Edit: 3/7/07
**UPDATE**

I am at work and UPS just dropped off my projector. Very quick turnaround by Panasonic. It arrived at their facility on Fri. 3/2 and I received it today Wed. 3/7. I was not expecting it back so quickly.

I will have to bring it home tonight and check it out and see how it works, but on the sheet included with the projector, it states that they replaced the Optical Block.

What does the Optical Block include? I am wondering what components make up the optical block and what would be considered new parts?

I will update again when I give the projector a run through today and tomorrow.

I own the Panny 900 too, purchased in February 2006 and so far it doesn't exhibit this problem. It's a stumper, there's an explanation of course but I can't think what it might be with the green line located where it is. If you got the 900 from Visual Apex I would contact them via email and send them these same 2 pictures for their engineers to look at.
My first front projector - a Kloss Novabeam 100 (1986).

It looks like a green edge on many of the graphic elements (on the top). Like look at the gray bars on the side, there is clearly a green halo offset slightly above them. Also the letter Y has a green edge around it. I also see a red line coming from the top of the image.

Just looking at those photos (and I know there can be chromatic aberrations from the camera) I would say it looks like misconvergence. No matter what, worthy of trying to get fixed from the vendor or warranty.

Thanks for the replies. I will contact Panasonic about getting it serviced.

Another question - regarding service. If I send it in for service, do they typically look everything over in the unit to make sure it all looks ok, or will they just try to fix the one issue and not look at other things that might potential problems.

Thanks!

Ok, now I am back from work again, so I turned on my projector and the Xbox 360 and now there is a distinct green line on the left and bottom sides of the screen and now there is a red line on the top and right side of the screen. They are all about the same size, just 1/2 is green and 1/2 is red. So green/red lines now border the entire screen.

Is this distinctive of a certain type of problem? I am going to call Panasonic, but thought it might be good if I had an idea of the problem is called.

Thanks!
