Shadow on left side of image--light tunnel problem?
I recently bought several reconditioned sharp xr-10xs from thecameraprofessionals.com, and there is a shadow on the left side of the image on one of them. after looking at various online forums, it sounds like it may be a light tunnel problem. anyone know how to fix it?

first try doing a factory reset through the menu. if it persists and the tint has a relatively hard edge to it, you may have a broken light tunnel and it's casting a bit of a shadow on the image. you might need to bring it in for repair, especially if it's under warranty
If it looks like a dark orange/brown band, its likely to be a Light Tunnel Failure. The Tunnel can be fixed thru the manufacturer, but it will cost plenty. You can also do it yourself.
For additional info, go to www.avsforum.com and search for "4805 Light Tunnel" and you will see threads about the problem...as well as DIY repairs.
I also posted a DIY replacement option since new Tunnels are virtually non-existent: www.avsforum.com/avs-vb/showthread.php?t=1304694
the light tunnel under the colorwheel has collasped or the projector has been jarred, knocking the mirror inside of the lens assy. out of alignment. Either way, it will have to be repaired by a technician.
is it a shadow or black line? the light tunnel is collapsing and needs to be replaced. you can get the part from a sharp service center and replace it yourself or send it to one for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com
Yes, you are describing a light tunnel failure and it can be
repaired. The parts are available, I just don't have any on hand
right now. I will be ordering more this week. The part is
about $40.00 plus shipping. The repairs can be challenging if you
are not experienced. The color wheel has to be removed to get to
the light tunnel The light tunnel is very fragile and easily
You would be wrong. Lamps do not do that. They either work
or they don't, they do not cast shadows or give half an image.
What is going on is the light tunnel has failed. It is a small,
4-sided mirrored tunnel that focuses the light into the optical
chamber. It is directly behind the color wheel. I've seen
this probelm dozens of times.
