Kodak Z612 won't turn on

To use umbrella lights, you need a hotshoe connection on top of the camera to attach a radio transmitter. This would set off the umbrella lights. Some high-end DSLR cameras do this very well.

batteries: are you using Li ion batteries that are charged up?

The Z612 works with SD cards, which max out at 2GB. It will not work with larger SDHC cards.

Question : What batteries can I use in my digital camera, and how long do they last?
Battery life depends on how you use your camera, the type of batteries you select, and how you handle the batteries.

Your camera is compatible with: KODAK Li-Ion Rechargeable Battery KLIC-8000 and KODAK CRV3 Lithium Batteries: A non-rechargeable battery. (so your battery might be in need of a change)

Using Your Camera

Some features, such as reviewing pictures and using the flash, require more power than others. Follow these guidelines to get the best use of your batteries:

• Limit the time your camera is in Review mode.
• Limit your use of the flash.
• Use the LCD Dimmer or Auto Power Off features, if available on your camera.
• Transfer your pictures to your computer using a compatible power adapter, camera dock, printer dock, or memory card reader.
• Check that the latest firmware is installed on your camera. See Software, Driver & Firmware Downloads.

Handling Your Batteries

• Wipe the battery contacts with a clean, dry cloth before loading it in your camera.
• When using your camera in temperatures below 41° F (5° C), carry spare batteries and keep them warm.
• Do not discard cold batteries that do not work; they may be usable when they return to room temperature.
• Do not allow batteries to touch metal objects, including coins. Otherwise, the batteries may short-circuit, discharge energy, become hot, or leak.

To both, I'm afraid you need to send the out camera for repair.

Camera flashes use a capacitor that holds the electric energy for the flash. It takes some time to charge and discharges very rapidly to generate the light pulse. Capacitors are notorious in their reliability. They tend to disconnect and die or short circuit and die.

In camera1234's case it might just died disconnected.

In sheranne case it might died short circuiting. In this case the camera should not be used since the battery might explode.

Try these procedures.
