fried talking whiz kid

[tinsolder]

hi benders out there,
i recently bought a talking whiz kid (the brown,old one),turned it on and it worked on batteries and by proper wall-wart. then i tried the next day,cause i wanted to search for bends,but it didn't work at all.anybody a idea what's wrong? other v-tech comps have that plastic-covered fuse-resistor but this one doesn't. i bent a German one successfully before and tried the english one.but it's fried. i checked all connections and they seem fine.please help.
