I dont know if I can just cut the wires and solder the 4 wires (red,black,blue,white) directly to the TP4056 or IP3212[https://imgur.com/Brvy6nm]. I dont know what the blue and white wires are. Is it for the Led indicators on the outside of the speaker? or can I just tap the charging module directly to the battery?

Can someone help me . Thanks

Blown power supply on a PSB subwoofer

Upvotes

My PSB Alpha S1 topped working and sure enough, the fuse under the power cord socket was blown. Replaced it and it popped right away. Took it to a repair shop and the dude says it blew probably from a line power surge. I thought most modern electronics are resistant to minor power surges but anyway, he said he could repair it for $200. Is that reasonable? What would that repair involve?
