Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, have you tried the RESET button?

Customer: replied 4 months ago.
It does not have one
Expert:  Louie replied 4 months ago.

Bear with me....

A recessed button right of the * - (OPTION) button before/left of the IVA-W520E name?

You may need a abllpoint pen.

Customer: replied 4 months ago.
Found it, still no sound yet!
Expert:  Louie replied 4 months ago.

Then it would be an internal hardware issue; sorry.

Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?

Customer: replied 4 months ago.
I'm an electrician, thanks for your help

Great on the DIY!

The primary suspect would be the amp / output IC attached to the aluminum heatsink.

Depending on the version, it would be something like a TA8273H or a variety of this amp module.

There would be instances that the fault may be low or missing supply voltage to any of these IC pins or even a cold solder.
