“More recently I found every time I switched the camera on the low battery sign was coming on”.
Does the camera work ok in spite of this low battery indication?
If so, just carry a spare set of recharged batteries. If not, forget about a Kodak repair, they start around £90.
That’s why I have a Kodak CX 7530 with a damaged LCD display not being used. It works fine if I just use the viewfinder and set it on auto. A bit like a film camera I suppose.
