Ope! Yeah, there's mine, the one in the far, lower-right hand corner. Guess that's what the problem was...that's pretty bad. They should have tried to fix ours or something. Poor Mametchi...I'm sorry I let you go dead, all those months ago!
ah, hope you consider buying a new tama
One of my friend had this problem once, I hope you dont give up on them ^^
maybe you should try opening the tama? Like what ChoHimetchi did
