No sound from left channel - TA2024

Hi everyone !

I have a problem with my Sure-TA2024 amplifier. After i returned from vacation my left speaker had no sound 🙁
I disassembled the unit in hope of finding a simple loose wire, but nothing.. Tried a new sound source, new sound cable, switched speakers, connecting the speakers directly to the board, nothing works. Only the right channel.

Any ideas, before buying a new one ?
Here's a picture of the board:
