this error is
"Reset position detect error when stepper iris is initialized"

Turn on the power and set to T (telephoto) end by rotating the
ZOOM manual ring. While observing the iris blades in the
lens, turn on the power again and check the iris blades in the
lens work properly. Inspect the iris drive motor of lens drive
block (Pin qh to ql of CN6602 on the VC-582 board), when
the iris does not operate. Inspect the iris reset sensor of lens
drive block (Pin qd to qg of CN6602 on the VC-582 board),
when the iris operate.

My i85 camera's lcd no longer displays what you are looking at. Just a black screen. All the menu items are there and working. The battery is charged. The power button is working as well as the lens open,...


The iris is probably shut closed or the CCD is bad. The iris controls the amount of light that enters the CCD (charged coupled device). Sometime the iris get moisture inside and cannot open. Or the CCD is defective. Leave it in a dry environment for a day. If it doesn't cure then return it to the store for a refund because the CCD will need to be removed and replaced.

The shutter on my NV15 camera is open but no image is displayed.


The Iris or CCD may be the problem. The Iris may be wet - preventing it from fully opening or closing (or it might be stuck). The CCD may be bad - preventing the image to translate into an electrical signal. Try leaving it in a dry environment for a day to dry.

The CCD is bad or the Iris is shut stuck. If it's the Iris just stuck, it might just have moisture - leave the camera in a dry place for a day. If it's the CCD - pretty much "kiss-it-good-bye". To replace the CCD is expensive - get a new camera.

I need a instruction manual for husqvarna viking iris machine


I have an auto buttonhole maker from a more expensive machine, but it plugs right into my Iris. I just don know how to use it, or how to embroider with this machine. I didn't get a manuel when I bought it then Katrina came through and the place is no longer there. Help please.

Black screen


I had this problem too. It's caused by grease on the iris curing (setting) and jamming it locked. The motor that opens the iris when you turn the camera on isn't powerful enough to overcome it, hence the black screen.

There's a tutorial online somewhere about how to fix it. But if you're like me and not that good at that sort of thing take it to a local camera repair shop and get them to fix it. Tell them what the problem is and that you need them to clean the iris blades. Emphasize you don't want them to grease them afterwards, just leave them dry and clean. The guy i took it to was very unsure when i told him all this but told me I was 100% right when i picked my camera up, and that cleaning the iris blades had fixed it.

It's been 4 months since I had it fixed/cleaned, and it's being working great every since.

PS. There's a strong suggestion Sanyo knew about this when they shipped it but shipped it anyway. It's not been proven one way or the other, but I personally will never buy a Sanyo product again.

Overexposure on outdoors shots


i think it is a case of defective apparture system. the system controlling the change of apparture opening has been locked. the reason may be friction in the blade movement or defective flex pcb carring the signal to the apparture motor.
