casio keyboard with weak sound and dim lcd

Cleaning dust did not fix. The DC9v adapter checked out okay but was getting reading upto 11vdc from multitester. Plugging Multi-DC power regulator gave same weak sound and dim lcd result.. 

suspect 1 = IC Amplifier TA8227

suspect 2 = test capacitors in the power panel 

Will post update soon about the issue.
