Fixed it

Things like this are always such a simple solution at times. Much like microsoft gamebar being the sole reason why my pc froze while playing any game, here was the simplest solution that only got solved today after years of giving up on it. The contacts to the speakers are merely some kind of conductive thread. What that means is that any dust or rust build up would eventually prevent contact between the thread and the contact points. Used an aluminum brush to scrape the contacts and thread wire and put some bit of foam padding to hopefully prevent any more movement of the threads since speakers vibrate and cause mini movement and it's now working like its supposed to, no cut off of sound at all. Nothing to do with over heating...

It's now possible to sell this tv off as fully functional or give it away or whatever, it's 100% normal now, jesus, why'd it take me this long to figure out the problem.

Might do just that, get a beasty nice 4k top of the line tv and get rid of this and sell it to whoever for a decent price. I bought it for like goddamn, can't remember but it was my first ever flat screen tv that I purchased for myself. I think it was around 80 dollars on black friday sale, or something like that so I bought it, had no idea about 1080p vs 720p, completely clueless so I didn't know this thing was basically just adequate not the best of its kind, no idea. But it's been with me for a good number of years. So sad when the sound went on it, and no one had any solution to it. Well if you own one of these DX-32L200A12 Dynex Sets, There ya go, I think I solved the problem permanently and you can too!
