hm.. open up the back of your tama.
see if there is anything blocking the sound [you should have undone only one screw]
if that doesnt work, try something like this:
get in a quiet quiet place.
hold the tama up to your ear.
can u hear a faint beeping noise?
if not do you hear a [can someone help me i cant describe it] clicking noise that doesnt beep but goes on. like a gear being turned in a really low pitch?
and how long has your tama been without sound?
cant comprehend what im saying?
go to the store.
get a new battery.
change the battery.
if you just got one within 4-5 weeks dont do it!
OR if you are totally fed up, reset it OR flip it to the back.
take the battery out. put it back in.
if you hear a BEEEEEEEEP the sound should be back on.
download and the sound should be on!
