Backlight doesn't work

My backlight doesn't work anymore. My solar battery is fully charged. When I try to activate the backlight I see a flashing triangle pointing to recover. Do I need to replace the secondary battery?

Re: backlight doesn't work

Go to this link; and enter the four digit code on the back of the watch, you should get a user manual - i do think you are probably right however. Hope this helps :)

I have this seiko solar chronograph watch for one year and stop working, I tried to charge it with sun light with no success, any idea ?

Replace the battery, the solar part doesn't mean it charges from the sun it has to do with the movement of the arms (I'm not %100 what that means) I just know it doesn't charge by the sun or any other light source.

What kind of light should i use to charge my watch

stick the mtg900 in a window sill for a day and that should charge it completely. If that does not work that means you will need a new capacitor. It might be easier at that point to buy a new or pre owned on ebay . they go for like 60 dollars or so.
even though they are solar they still need a battery to store the electricity needed to run the watch. A capacitor will need to be replaced from every 5 to 10 years.

Flashing charge

I couldn't find your model on thier web site but this range appears to have solar panels to charge the battery. Place your watch in bright sunlight or under a lamp (not a hot one) to charge the battery.

If this fails, consult your nearst dealer.

My Casio Gw-300 G- Shock watch face intermittently goes blank altogether. Immediately prior, the solar battery shows a full charge, (in addition, the back-light battery is less than a year old). When the...

From your description the solar cell charges the battery and keeps it topped up. I think the rechargeable battery is the problem because when the screen goes blank the battery level drops to low and the LCD blanks out which would explain the intermittent operation of the watch. I think it is worth getting it checked out with an estimate.

yes , though the battery is charged by solar cell it does need to be replaced after awhile. So you can get the battery replaced, if it is the battery .

If its not the battery than the solar cell capacitor can also be replaced.

This should be checked out by a professional watch maker they can test the battery and the charger for you for free.

Protrek casio watche just stoped working

Is it SOLAR?
I have a Casio Pathfinder, SOLAR, ATOMIC! They have a permanent battery!!!
It must be exposed to the sun occasionally to charge. If yours has nothing on the display, try putting it out in the sun for a day. Put it in a window, sitting on a window sill. Depending on how little charge it has, it may take as long as three days to charge.
Otherwise, the alternative is calling Casio, getting an RMA and sending it to them for a battery replacement.

My MTG900 says, "Charge" on the screen...I got it last Christmas, does this mean I need a new battery?

CHARGE means you have to charge the watch. It depends on what type of movement you have. If it's solar powered, you need to leave your watch under the light to charge it. If it is battery powered - you haqve to buy the new battery and fit it. Rate me,plz.

Blank screen

if this is the same as my watch, it's solar powered and when it gets TOO LOW< it will blank out and begin to charge .  Stick it in direct sunlight for a day if you can.  You can also stick it under a regualr lamp, but it will never get fully charged, but it should be enough to operate at least.  The battery meter is the top middle dial on the face.

Casio pro-trek PRG-60T Buttons no longer activate anything.

Send it into repairs and they will send you an estimate on what it would cost to fix it. Give them a call at 800-706-2534 option 2.
