All of a sudden my kodak af 3x optical asperic camera would not turn on. how do I fix this problem?

This is a camera Kodak AF 3x I used to snap that pic it has a good lens it works perfectly

Try eBay...

My guess: your sony card is a SDHC card. Or when it can store more than 32 Gbyte, it is a SDXC card. Both won't work in your Kodak camera, because it only can handle MMC and SD cards.
You still can buy SD cards, but most of the time they can't handle more than 2 Gbyte. Take care, because most memory cards with 2 Gb capacity are already SDHC.

Hello Bernard, There seems to be a lot of this going around !! Possible bad battery contacts or a faulty main switch. you will need to have it looked at by a tech.

One source is here.

it wont turn on

SAME HERE :(

Make sure your batter is fully charged, and is not bad. This kind of reaction can happen with a weak battery or partly charged.
If that is not it, then the camera needs repair.

Here are the steps:

1. Make sure you will install a new or fully charged battery/batteries into your camera.

2. Clean the battery contacts.

a. Remove the battery/batteries and the memory card from your camera, then wipe the battery contacts with a soft, clean cloth.
b. Reinstall the battery/batteries into your camera

3. Without the memory card,turn on your camera.

If issue persists, call 1.800.235.6325 for repair.
