RCA high current discrete amplifier glitch.

[EtienneD]

So I'm watching netflix on my ps4 or even my phones music though an 1.8mm cable plugged in a console then inside the amp/receiver and then BOOP some scratches in the sound like some cables disconnected while the amp is open and then nothing. No sound and the amp stays open and some popcorn sounds happen like crackling. I'm trying to figuring this out why the amp suddently starts freaking out on me while almost unused (music at mid lvl and no hard task demanded)

I'm thinking it's and electric problem but maybe someone here can help me.

You could check for a blown fuse. If there aren't any on the back you can look inside.
If we're talking about an RCA brand receiver they were very cheap and by now they are pretty old. Not surprising that one could break.
