Recently bought Kodak Android 9 TV, but the sound from the tv speaker's are not satisfactory...
Not satisfactory in what way?
In general, you can't really expect much from flat panel tv speakers, especially from a company like Kodak that isn't really known for their tv's. They are usually small and not very powerful, leading to a quiet and thin sound. I saw on one of their tv's advertising "true bass" as if 30 watts of audio is loud. In reality, that's not much, and you won't get any satisfactory bass from it. It may be ok for a small quiet room at best.
Chances are, you'll be pushing the volume limit out of the box. Even if you could run an EQ within the tv, you'll likely end up with a lot of distortion trying to get a more full sound.
If you are looking for more volume or room filling sound, you'll really need a dedicated sound system. Even a basic sound bar and subwoofer would be worlds better than the built in speakers. For comparison, I'll go back to their marketing. They emphasized the amount of bass you can get from a 30 watt total system. I'm willing to bet that's the maximum wattage, which leads to distortion in most cases. The maximum wattage that still gives you a clean sound (aka RMS wattage) is about half that. So now we are at 15 watts total, and that is used for all frequencies on 2 tiny speakers. Bass requires a lot of power and a lot of speaker cone area to move a lot of air. A good stand alone system will have a larger dedicated sub powered by its own amp. The sub alone would be about 50 watts RMS to even begin to notice it. Ideally it would be 100 watts RMS or more (depending on room size) to be satisfactory. The main speakers would need about 25 watts RMS each to provide enough volume while still being able to have a decent mid range to provide warmth to the sound.
So you're looking at starting with around a 150 watt system. That will be fine for most people. If you are listening in a noisy environment, have a large room, or just really like to crank the volume, then you may need to consider something more powerful.
