Even then, there was a static or white noise sound clearly being emitted like an old cassette tape

No boom to the subwoofer, hardly any noise at all

About 3 months after buying it the speakers started to make a crackling noise that would just come out of nowhere which turned into loud static noise

Caused a loud snapping noise every time I changed a channel

Once I left the TV on for the dogs as I sometimes do, and came home to this awful noise.

every once in a while it emits this incredibly loud static noise.

Apparently this model has a defective fan that makes a really irritating humming noise
