I have an old Casio VDB 100 that just went through a battery change. Ever since, there is no response to the touch screen, and the message OPEN appears in the upper right.
- I have removed and replaced the back, and followed rest instructions printed on the inside.
- I have compared images online of the open back to mine, everything seems to be in place, including the little springs.
Anyone have any experience with this watch? I hope the shop didn’t kill it.
