How To Repair YAMAHA PSR -175 | Power Supply Fault | Mere Sapno Ki Rani

This YAMAHA keyboard was not getting switched on, So we deassemled it and rectified the issue. We found that its fuse needs to be replaced.
It is caution that, Changing the fuse may not be the only problem that may cutoff the power supply in the electronic circuit. It may also arise due to faulty adapter, loose power connector or dry soldering.

Will the keyboard work on batteries if the fuse is gone? Is this just a mains supply issue?

Check power section area in PCB , either its fused or audio amplifying IC had been damaged.
