i can not remove the black plastic that cover the battery, i only lift a little only to see that inside there is a old small battery with corrotion

Blacki, excellent research and solution!! Thanks a lot! Needed both cables as shown in your picture to get the speaker back to work.

(The battery had green crust and some 'sweat' on the top contact. The upper left varistor (or whatever) as indicated in your picture was loose an its contacts black. Making a short cut just there was not sufficient. The upper wire alone as in your picture was also not sufficient. The lower left varistor (or whatever) was still in place. The lower wire from there to the right as the shown in your picture made the speaker loud again!) Needs some patience to solder in that tiny area...


Thanks again!

Hello, thanks for these instructions! Unfortunately I have not managed to remove the black plastic that holds the speaker and hide the interesting part of the PCB for this repair.
Can you give me some advice? It seems very hard to remove it without breaking the whole thing.
Thanks in advance!
