Sony VPL-HW55ES top & bottom of image bowed

Hello all i have just received my HW55ES and i am having trouble setting it up.

I have my projector ceiling mounted and is level and stright and I get no keystoning issues but the bottom and the image is curved like this.

h**p://cdn.avsforum.com/8/82/825beaee_vbattach165574.jpeg

I am using a tab tensioned screen so i know the screen is flat to prove this i decided to take the projector down and sit it on a table to see if the top of the image would bow as I have turn the projector the right way up and it does.

I also got the projector central to the screen so I am using no lens shift and the bow it still present.

Am i right in thinking that the projector is faulty or am I missing something?

It has to be the projector as the bow moves from the top to the bottom of the image depeding on the orientation of the projector.

I thought it was because I was using to much lens shift but now I have taken the projector down and got it central to the screen i cant be that.

Also tried moving the projector back as I thought it was to much zoom but that does nothing either

Any Ideas?

Thanks Adam

I just got mine is this week as well and have the same exact issue. The top seems straight but the bottom is bowed. Hopefully someone knows what causes this.

Going to contact the store I brought it from today and see if I can get a replacement sent out

Is your projector ceiling mounted?

Just spoke to Sony they want me to send them a picture of the fault so a tech can have a look at it to see if the fault is with the projector.

Will update this thread with the outcome

Yup ceiling mounted, I did some reading online and some people found that it was the screen being out of shape. I am going to look at my screen when I get a chance to make sure it isn't bent/warped.

You should do the flip test and take your projector down and table mount it to see if the bow moves from bottom to top.

If it does then it confirms the projector is at fault not the screen.

I was just about to suggest doing the exact same thing. Anxious to hear your results.

I've had mine for 7 months. I have it shelf mounted and it has always bowed very slightly on the bottom of the screen. I thought about sending it back, but at the time I got it, there were no replacements to be had and I had waited so long to get it. Honestly, after a very short time I just forgot about it. It really doesn't affect viewing of movies or TV... only test patterns. The masking around my screen is a black hole and absorbs any extra light thrown at it, so I just let it spill over. Problem solved : )

Maybe mine is different as when watching a movie in 2.39:1 for example the bottom of the visible image in bowed as well.

So its not just the extreme edge that is not straight but the entire bottom of the image is distorted.

My HW50ES has a similar bow at the bottom. I figured it was a problem with my setup, even though everything appeared to be level. I spent a ton of time attempting to correct the issue, but ultimately gave up. The thought never crossed my mind that the problem could actually be with the projector itself, until I stumbled across this thread.

The bowing used to bug me, but I don't really focus on it anymore. At this point I don't want to bother with the hassle of removing the projector from the mount, shipping it, etc... especially since Sony could just claim that it falls within acceptable limits.
