Need help CR-2040 blow fuse

Hello. Can anyone help me?

I have bought a Yamaha CR-2040 a few week a go.
Everything was fine until yesterday.
When I push the power buton the 1/2 power and overload indicators illuminate.
Than the unit shut down.

I found that the left 3.0 Amp/ 250 volts fuse blow out.
I replace it.
I take off all the speakers wires. There is nothing plug in the receiver except for the AC cord.

When I put the power back the 1/2 power and overload indicators illuminate again and the unit shut down again after a few seconds.
The same fuse was blow.

Does anyone can help me?
I like so much that receiver.
Thank you.

Probably a blown output transistor. You need to test them with a DMM. The are the plastic to3p transistors on the big heat sinks.

Thank you I will check
