TV went off while watching, won't power on now.

Hey guys,

I'm back again with something else broken!

So the other night I was watching YouTube videos through a fire stick on my TV, when it just powered off. Well we tried another device in the wall socket, and it didn't work. So we assumed it was the wall socket.

So we plug it up elsewhere, and it powers on for a moment, then goes out. The red indicator light doesn't even come on.

Before this we were having a lil bit of problems with the side panel, where it would act finicky.

I read it might be a capacitor, or loose cord. I've tried wiggling the cord.

I'm a bit apprehensive about opening the TV, I don't want to hurt myself. But I do want to fix it. Any advice?

Thanks

I will provide more photos if I need to.
