Casio F91-W how do I reset the display?

Display has gone haywire - lots of 8888 and some other symbols. I have replaced the battery, but problem remains. Can I reset somehow, or is the chip blown?

This may sound dumb but make sure the battery is in the correct side up. There should be a + or - symbol on top of the metal piece that snaps over the battery. If that's correct get a pair of tweezers and spread them open, and touch one side to the top of the battery and the other side down inside a little hole with ac marked beside it. That will reset the watch, and your display should come on.

mcdevito75 here, Casio uses an LCD crystal, Liquid Display Crystal, during a battery change any, any un do pressure remopveing or replaceing the battery could destroy the LCD. Take my advise, with a casio watch, look for a small watch repair shop in your area for the battery change. I"ve ruined many of my casio watches during battery change.

I have a Casio 1470 pathfinder watch. I did not use it for several years The batteries ran down, have replaced them and now have no display or functions


mcdevito75 here, I would see the jeweler who installed the new batteries and ask to have the battery install double checked so they are makeing proper contact with the LCD movement. In the meantime you can try to hold down the MODE button for a few seconds and see if the display appears, also if the display screen has turned very dark, your Casio may have had it, as the LCD display could have gone bad. New batteries should bring up a display even after the watch has been stored. Hopefully the display is still a grayish color and the new batteries need re-alignment.

Poor cassio watch display


You don't say how old the watch is and whether it has always had a display problem. I have seen several watches with weak displays, but generally they are older watches and I suspect the problem involves a corroded contact somewhere in the "movement". You might want to visit the Casio website and download a copy of the manual for your watch. It may say something about the display. If you watchis fairly new it may still be under warranty and again, contact Casio to see what you need to do.

Please help me to replace battery on my casio F-91W


This reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, similar to your F91-W. After the new lithium coil cell is installed and secured with the spring clip, the watch may show random segments in the LCD display or may simply be blank. Insert a sewing needle, paper clip, or blade of a small jeweler's screwdriver into the hole on the back of the movement stamped "AC" (All Clear) to momentarily connect the gold plated contact at the bottom of the hole to the stainless steel battery clip. The battery clip in most such Casio watches is connected to the "+" terminal of the coin cell. This will reset the CMOS chip and it should start up with the watch displaying 12:00 and the date at 1-1. Then, use the control buttons to set the time and date in the normal fashion.
