Hi My question is maybe absolutly dumb for someone who knows a bit about electronic devices but : I used an 9V AC adapter instead of 6V in my speak and spell, which killed it. Is there a way to fix it or is it definitly over for the poor little creature ? Please, try to answer something like “it’s absolutly not a problem !” Thanks a lot !
With electronics there is almost always a way to fix it. Mainly it comes down to cost effectiveness. Without looking at the board or the schematics it is hard to give you a firm answer as to how easy it will be or costly. You may try taking it apart and seeing if there is an obvious fuse in it. If there is one it would have fallen on it’s sword to save the rest. If that doesn’t work try running an add on Craigslist.org about getting it fixed some old man with nothing to do may do the repair for little to nothing. If nothing good comes from that, you could try the local TV repair shop. That was made before electronics really started getting miniaturized. Which may make things cheaper and easier. The damage should have been contained to the power circuit and not spread beyond that. I know really not the answer you are looking for. I don’t know what those are worth but I don’t see it going over the local TV repair shops minimum.
Axel absolutely not a problem ;-)take a look at the attached images. I do not see any fuse or fusable link but that does not mean they are not there. Check the diodes on the power supply and see if they are okay. I also attached the schematic, just in case you can fix it. Parts should be readily available at companies like Mouser.com etc….good luck and have fun
My old one was not working, followed advice on this page and checked continuity on the diodes in the power supply, sure enough there seems to be a burnt diode! Will have to doublecheck but I’m thinking a new zener diode of normal spec should work.
