Black screen problem


A lot of people that bought the first generation HD1 have had a problem whereby the LCD screen goes black, but the date, image size, old pictures etc. still shows up on the screen, so it's not the screen itself malfunctioning.

This especially a problem if Sanyo refuses to honor your warranty because, like me, you bough the HD1 early on eBay and thus they claim you're not the first owner, and therefore they don't have to honor the warranty.

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 yourself. 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.

E:61:30 error message


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.

I own a JVC GZ-MC500 camcorder. The iris blades are stuck shut I beleive due to old grease and or lubricant. I cannot figure out how to open up the lense housing in order to get to the iris blades to...


Its quite complicated to open. You have to start from the battery and card cover, remove those 4 screws, then the front cover(on that side) and power supply board up to the CF mechanism and connecting cables until the two halves will be separated. Now the other half where you can find the lens assembly is easier to dismantle. Observe correct screws when returning. Good luck.

Saying lens cap on won't record!


Your iris stuck up contaminated by the grease of lens mechanism. To clean, the unit must be opened up to where you can access the lens assembly and remove the iris unit assy then the two curtain(shutter) and clean with video head cleaning solution or any alcohol base cleaning agent. Re-assemble it but test the shutter first before assembling the camera completely. To test, open the shutter(curtain) manually by your finger and must close freely once released. Also clean the surroundings for some oil near the iris unit to avoid it from coming back to the shutter.. Good Luck

I have a JVC GR-DF450U camcorder. The playback works fine but the is no display when recording.


If you mean no picture during camera mode(that is all black screen), Something must be done to your camera. Iris motor unit fails to open causes the problem of no picture since iris is close. Solution, clean iris curtain, needs skill. I suggest have it checked by qualified person. Hope it helps, Good luck

Hi,
Model and brand will help me to provide you exact info about aperture (iris) control problem in your camcorder.
Usually IRIS control mechanism got stuck in camcorders and can be released by taking it out from lens mechanism to clean its sliding filters.
Let me know model and brand for further technical info.

My lcd and view finder are unable to show subject


The problem you are having is called a "stuck iris" Inside the lens are two thin plastic sheets that slide over one another that limit the amount of light that comes into the lens. In some Sony camcorders, the motor or "actuator" that drives the iris, or moves the two sheets which are the iris opened and closed. The actuators sometimes leak oil onto the plastic sheets causing them to stick, so the light coming into the lens is stuck at one level. Some technicians will recommend lens replacement (expensive) but many times the iris assembly can be removed from the lens and cleaned. Try to find a service shop that will clean the iris rather than replacing the lens.

Recording


I would bet that the camera iris is stuck closed. On some of the Sony cameras, the iris actuator (a small motor-like device) leaks oil onto the two slippery sheets that slide acrossed one another and act as the iris. A qualified tech can pull the iris assy out and clean it. I have repaired many Sony cameras this way. Sony usually recommends replacing the lens assy which is expensive
