I have a Kodak Z7590, the power ring flashes amber

Here is the link for this camera at Kodak: Kodak Z7590
you may try to set all menu settings to default. Flash problems can sometimes result in not correct settings of settings for other modes. There may be a setting to set all or reset all to factory settings or default, or something like that.
If that does not fix this, then there may be some problem in the internal workings of the camera, and it will need repair.
If you can take pictures and you are able to view them as well, ane the problem still is there, then some problem may exist internally with some components.
