, the microcircuit is heating up. This happened due to high voltage (charging from a soldering iron 100 watts). Where can I buy a motherboard or main un ![photo_2024-11-19_01-08-11|668x500](upload://vGImuJ4yRUdhtKDKQdQlOXruqB5.jpeg) ![photo_2024-11-19_01-08-10|375x500](upload://mMZCIEhA8er70T1tn7B6twPqXZy.jpeg) it?

Unfortunately the motherboard for this device isn’t something we’d carry as far as I’m aware. Sometimes we can cross-reference individual components from a board like this but the motherboard itself you will likely need to source from a repair specialist, or salvage from an old model of the JBL product this came from.

I did not expect that JBL does not have high voltage protection, there is no fuse. I just used a more powerful charger. For phones there are back devices up to 120 and no warnings that this may damage other devices. The column is almost new and now it will have to be thrown away.
