I AM USING PANASONIC LUMIX 10 MEGA PIXELS DIGITAL CAMERA. NOW IT CAN'T PLAY BACK THE PICTURES.

Try NOT connecting your camera to your computer.
The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program, such as Picasa.

Hi,
The very first thing to do is you have the lumix driver in your computer. Then use the firewire to paired them. Some brands of digital camera give you difficulties to transfer data from mass memory ( camera memory and is not additional memory <mmc/sd>) to other media like computer. It is invisible when trying to import and all you can do is just enjoy the data / pictures by using play back features in your digital camera. So what you should do is just connect them as usual ( remove the memory card before commence this task) and seek the pictures you are looking for in digital camera. If nothing found there, you can not get the pictures imported then.

If you take out the sd card you should see a slide on the side of the card. Usually the card will indicated which position is locked or unlocked.

You can download a copy to your computer from the support section of the Panasonic web site.

I have Panasonic DMC-FX100 , Lumix 12 Mega Pixels.
When I on my camera its shows that "Please turn camera off and turn on again." when I turn off the lence cannot shut down , it makes noise. When I turn on, the lence move again but cannot turn off.

You need to format the card in the camera to optimize it.

It sounds like you have the review mode, which won't allow you to take pictures - change the mode using the dial at the top of the camera. Change the dial to Auto, "A", and you should be able to take pictures.

■ Number of pixels
Select a higher number of pixels for clearer
pictures when printing.
Select a lower number of pixels [ ] (0.3M
EZ) to store more pictures. Fewer pixels also
means it is easier to send pictures by e-mail
or use them on a homepage.
■ When the aspect ratio setting is
[h]
DMC-LS75/DMC-LS70
(7M)
3072 × 2304 pixels
DMC-LS60 only
(6M)
2816 × 2112 pixels
DMC-LS75/DMC-LS70
(5M EZ)
2560 × 1920 pixels
(3M EZ) 2048 × 1536 pixels
(2M EZ) 1600 × 1200 pixels
(1M EZ) 1280 × 960 pixels
(0.3M EZ) 640 × 480 pixels

on the menu I believe the Panasonic calls it aspect ratio

some of your picture was currapt ,during the transfer from camera to PC the current was unstable or some connot read by your computer.

There should be a button on the camera to turn on the LCD screen so you can see whats going on. Here is a link to the manual. http://service.us.panasonic.com/OPERMANPDF/DMCLZ1.PDF Look on page 10, button 6. After the camera is turned on, wait 20 seconds, then hit that button and see if the screen turns on. Hope that helps.
