Tamagotchi V3 shuts down/ screen goes blank

Hey,

I have recently found my old Tamagotchi V3 and put in a fresh battery, it resets and the egg appears but after 10-20seconds (I haven't timed) the screen will go blank and all sound stops.

As far as I know it has had no water or sun damage, and i don't think it is the battery as this battery works fine in my V4.

I have not opened it up yet, as i haven't done this before and i do not have a screwdriver small enough.

Does anyone know what may be wrong with my Tamagotchi or how to fix it?

Any suggestions or help would be fantastic

Thankyou

Without taking it apart completely it's difficult to guess.

However, as first steps you can check that the battery type is correct CR 3032 3V (even if it works ok in your V4) and then do a careful visual inspection of the area / circuits surrounding the battery to check for any signs of rust / corrosion that may have been left by the previous battery.

See this post by jirachi for more info on cleaning corrosion from a tama: https://www.tamatalk.com/IB/topic/193121-frozen-in-time/?do=findComment&comment=3331073

Thanks for your help, everything look fine from those aspect.

I'm going to buy a glasses mending kit to get a small screwdriver and have a look inside to see if its a connection issue
