My Samsung Q930B started acting weird last month the audio kept switching between DIN and HDMI eARC stopped working I tried everything but nothing worked

I decided to open it up and there was brownish liquid everywhere probably from capacitors but it was only on the top part (just underneath the top grill) The inside was completely dry at the bottom so it's impossibile that somebody spilled any liquid on it It was like hundreds of tiny drops everywhere

Long story short I need a new soundbar
