so i am up in aspen shooting x games and shooting a run down the mountain.... panned my camera past the sun and then next thing i know my iris wont work anymore. when i scroll it up and it says closed its still open and even hitting auto iris it thinks its adjusting according to the lcd but no change in the image... also if i dont turn it on in complete darkness the lcd shows these crazy black lines vertically in the screen and tested the record and it records them as well... but if i put the cap on and turn the camera on it ther remove it they wont show.....sounds like a bad sensor but the iris is doing nothing as well.. cant quite make sence of it.. also the sensor in the hvx should be able to handle a pan past the sun as i have shot many snowboarding shots for years into the sun and silhouetting the rider... please help with any advice before i waste anymore hours of time on the phone with panasonic.......i still havnt gotten a hold of a pro video tech....
 
My iris roller doesn't always make contact. I find I have to push the iris wheel in a bit sometimes to get the cam to iris up/down.

if it was a bad sensor the iris would still work in manual mode. Are you sure the footage is not being recorded correctly? the only part of the camera with a sun warning it the viewfinder. Could you have just broken your view finder and your cam is still fine? Try the pull out screen . Also try the outputs to the tv in your hotel. I think this is just a viewfinder issue, not a lens issue. If you record and then play back it could be playing back on the same damaged screen.

@Jason
The Iris is making contact if the stop displayed on screen is changing.
 
I suspect the iris wheel contact is worn or not making a good contact. I had one replaced once on a DVC30 that displayed the same behavior.
 
I am having the same problem. I panned past the sun while shooting in the pipe at Sierra At Tahoe. What was the final diagnosis on your camera?
 
I'v read else ware that you can fry your chip shooting into the sun. I would think the cam is pretty tolerant, but the lens does magnify the intensity. Think of the lighting a piece of paper with glasses except much more extreme. I'd take send it in to get repaired unfortunately.
 
Yup, I've seen an almost new DVX100 go to waste because it was aimed almost directly against the sun for about 15-20 minutes. After that, it was all black and the ccd chips were fried. Maybe yours are damaged and not totaly damaged yet? This is a big no-no with any camera really. The same thing happens to the image sensors as when you take a magnifying glas and aim it towards the sun to create one extreme hotspot to burn ants or whatever =P
 
lol. That's scary. Is the camera still at risk if you have your incam filters on?
I was shooting a bunch of time lapse sun-rises and sunsets and was pretty timid about it.
What are some precautions or rules of shooting into the sun? Anyone?
 
Same question ^^^. This worries me as I have shot similarly to Zblock. Not for long periods. Just need some guidelines to follow so we don't mess up the sensors.
 
I've shot sun rise/set with my dvx and had no problems. I did have a UV filter on my cam (although not sure that makes a difference) At noon int he summer the sun is closest to us. Sun rise sun set in the winter it is furthest from us. i dotnt hink its a big deal to shoot rise/set sicne the sun is nto nearly as strong. Panning by it midday whent he sun is close is a much bigger deal. As others have said, if you can look at the subject without sunglasses your int he clear. Midday sun you cant stare right at and neither can your camera.
 
I had 2 nd filters with 1/1000 shutter at 720p 60, my f stops were between 5.6 and 8 depending.
i have shot many a sunrise and sunset with this camera and have not had a problem, I can see some minor lines in the image, but there is an image, and the iris control does nothing at all.
