Sony PVM 20L5 Problem

[Roge_NES]

Hello guys! I received an 20L5 PVM that unfortunately does not show any image.
There's no degaussing sound when turning on and neither do the buttons on the panel light up, only thing I get is sound from Line 1 Input.
I'm unable to switch to any other input.

I already opened up the case to check if they were any loose connections or damage but nothing, any help?

There's a button called "Control" right underneath the power button that lights up the panel, have you tried pressing that?
