Iris is not the cause of black screen.First confirm that shutter is opening as soon as you switch on camera.If shutter is not opened and you can't see live view on screen except black screen,then certainly there is problem with shutter assambly.
If shutter opens and you see black screen then there is problem with CCD.

I have intermittent problems of this type too. Occasionally I get a blank screen in the display mode.
Does the red light on the back of your camera flash while the screen is dark? Mine does.
It is beginning to bug me a lot. It may be because I got my camera wet in the past (and hence I have broken my camera), but I doubt that would result in a partial failure.
I think that the Xacti HD1/HD2 has issues a bit like a blue screen of death on an old Windows computer when faced with storage problems.
I.e. it works but crashes sometimes when it cannot store to its storage medium.
These things work for me
1) Turning the power on and off via the button underneath the screen.
2) Removing and re-inserting the SD card.
3) Turning the power on and off by removing the battery.
4) Using a different (and faster?) SD card.
I am still using my HD2, but I am finding that I must attempt solutions 1-3 about once a day.
It could be because the card I have been using recently is not fast enough. The HD2 accepts both SD and SDHC cards. My SDHC card (which is newer) seems to result in fewer problems, either because the SDHC format is more suited to the Xacti HD2 or becaues the SDHC card I have is faster that then SD card I have. I suspect problems with the speed of the card. I am using cheap SD cards.

As I have been writing on other HD1/2 problems, sometimes it can be the card which is an issue. If the card is too slow or perhaps corrupted then the device can find it difficult to record.
This and other soft faults (that are reperable by turning the power on and off, changing or reinserting the card, removing the battery) are often indicated by a flashing red recording light.
