I have a E250. After changing broken LCD (only LCD, board for LCD is original) - speaker and buzzer don't work. If I tried other LCD board, all was ok, so flex and mainboard are ok, problem is on the LCD board. Has anyone got solution for this or schematics of this board? I only have schematics fot mainboard... Thank you for your help.

It is solution for speaker faulty, but my motherboard is ok. I can change any ic on motherboard, but board for lcd will be already faulty.
