Hello all- I have a G-5600 2597 module Tough Solar I have had for several years; it started developing charging issues a few years back and I started wearing my G-8000 instead, thinking I would get around to getting the Solar back up running. I finally replaced the battery with the factory replacement which after a few hours showed a full charge. The issue I'm having is apparently not uncommon, but a fix isn't clear on the interwebz. Everything looks normal, but occasionally when I try to illuminate, it flashes briefly and the word "recover" flashes over and over for a few minutes, then recovers to a normal screen. It doesn't do it all the time, and the battery shows a full charge. Is my watch failing, or is there a simple fix? The battery was a genuine Casio replacement so I don't think that is the issue. FWIW, I have never seen the watchband I have anywhere else- it is a combination of the standard resin and a nylon webbing material. I want to keep wearing it, but don't want to be without the illumination function. Thanks.
