This is my first post. I have a prg-90 and have been using it for the past year. All of a sudden, a couple of months ago, the display vanished. The charging indicator on the watch is blinking. The problem began after I had left my watch in the bathroom overnight. Could it be moisture problem?
I tried recharging it with the sun and bulbs and only got the display to turn on once and then it died again without any warning.
Do you think it's a moisture problem or just not enough direct sunlight? It's winter here in Boston and there's not much sun. I'm usually indoors ( musician ). Anyone has any experience with this? It is out of warranty.
