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.
