HI-FI SYSTEM WON'T TURN ON!!!

Hello everyone and thank you to those who will help me!!

This problem occurs with a Sony MHC-RG330 hi-fi system that is 14 years old.

Yesterday, I was listening to the radio, as usual, when I decided to go to bed and turn it off by pressing the [POWER] button, then I disabled the Sony Demo mode by pressing the [DISPLAY] button.
Then I plugged in some headphones to this hi-fi system for the next day.

The next day (today ^^) I decided to listen to music (as usual) by removing the headphones that I no longer wanted to use with this hi-fi system. I pressed [POWER] but nothing. It does not want to turn on anymore. I tried pressing [DISPLAY] to hopefully bring back the Sony Demo, but still nothing!

I checked the manual but nothing corresponds to my problem. I should mention that the red LED on the [POWER] button does not blink. There has been no power outage, and I have never taken this system apart.

I do not know anything about electronics at all.

Also, the headphones that were plugged in are some I found randomly in a drawer at home, headphones from a Sony Ericsson phone.

Thank you to those who will help me!!!

Best regards,
Alexis

    I don't know much about it, but it seems like a purely electrical or electronic problem. Like a short circuit in the chain or something. And is it giving off a burnt or melted plastic smell?

      Hi!
      And thanks for your reply!

      No. No smell of burning or melted plastic...

      I'm going to take it apart and see what's inside and I'll let you know!! :)

      Try Koehly's technique first, and if that doesn't work, do what you can afterwards...
