Try tapping the side of the source button, the last button on the right on the bank of 4 switches. Try switching it on and off a bunch of times, if it's really dirty/ oxidised you can lose a channel, same with the speaker buttons.

Hi!

There is no protection in this amplifier. Check whether DC voltage can be measured at the speaker output. If you measure more than 1V, the STK amplifier IC is dead. If not, and both sides sound normally on the headphone output, then the speaker selection switches are broken. If the STK IC is damaged, it is unfortunately beyond repair. You can't get such an IC anywhere, or if you can, it's a fake or just as dead.

The replica ICs aren't too bad. My STK2038 went pop and a cheap replacement on AliExpress, 7 quid. Sounds just as good.
