Hi All We have one of those cheap battery powered novelty sound generator toys
- 16 rubber keys, each of which when pressed plays a short 'amusing' sound clip. The Granddaughter like her 'spooky' themed one, but there are other styles available.
After a fair bit of use the sound appeared to give out, and so I replaced the batteries - 3 off LR44. I used some cheap but not super-cheap replacements form eBay (the originals are unlikely to be of high quality!). However I am still getting no proper playback, just a short 'phht' noise as each key is pressed.
I've taken a look inside and there are no eg. Electolytic capacitors to fail, so I'm wondering what the failure mode might be:
- replacements batteries too shoddy?
- flash memory inside the sealed CPU failed?
- some PSU components I am missing?
Thanks for any thoughts - it's not a big deal but we had a similar failure in a new unit a while back and I would like to know what occurs.
Cheers J^n
