DMC TZ3 lcd sceen ok on playback no image on shooting

camera will require service

Mine is doing the same thing. I used it last week and all was fine and today black. Someone help us!!

Assuming you have fully charged batteries, there's nothing you can do but take it in for service.

Sorry - it can't be done. The Panasonic DMC-TZ3 does not support digital negative or RAW formats - JPEG or .jpg file types only.

The digital negative and RAW formats are typically seen only on the dSLR and other ProSumer (and up) cameras. Setting your camera to save the in the highest resolution (largest file sizes) possible is the closest you can hope to get to RAW, and still come up short. You'll get the most detail possible - but that's about it. RAW is a great way to shoot - but sadly, you won't get it on this camera - and probably not on everyone like it.

I hope this was helpful. Good luck!

I found 2 different Lumix TZ3 cameras.
http://www2.panasonic.com/webapp/wcs/stores/servlet/PNAEndecaSearchCmd?N=779832097+250033510&Ne=&Ns=&Nr=12001&No=0&Ntt=tz3&Ntk=SupportSearch&URL=vSupportSearch&cmTag=false&cm_sp=&cn=&catalogId=13401&storeId=15001

In the manual, I couldn't find a reference to a bluish color.

In FAQ's, I found the following:
What is “Intelligent Auto Mode” (or IA Mode)?
“IA mode” automatically activates MEGA O.I.S., Intelligent ISO Control, Face Detection, Intelligent Scene Selector, Intelligent Exposure, and Quick Auto Focus to match your subject and shooting situation. IA Mode is a great mode for beginning photographers

have u droped it ever

Were they shot with the TZ3 or in another camera or from a computer?

If camera shows Menu item or any on-screen display in LCD but no live view to take picture then it can be either aperture problem or defective ccd imager.
And if you do not see any display icon in LCD then of course LCD section is bad or LCD back light is Off for some reason. Try to see faint image in LCD if it is totally blank by pointing good amount of light with flash light or some thing.

The shutter is locked (temporarily); probably because a picture was taken of absolute darkness ... the camera is trying to save the image.

Remove the batteries...

I assume you are not shooting into sun. Try shooting with camera in its default settings and mode set to Auto Normal.
