Tv poor sound quality

get to the audio in settings and adjust bass and treble effects

, make sure you have a HDMI cord and read the book that came with your TV sometimes you have to change the settings to PCM, it's very important to have the HD cord that controls picture quality and sound

Unfortunately, the speakers on most flat panel TVs, to put it bluntly, stink on ice. They are there only because the manufacturer is required to put one there. Most manufacturers assume that users will hook up an A/V receiver or home theater system to the TV for better sound quality.

You might have a defective audio amp. One thing you can do is try to compare the impedances of the audio amp's left and right channel (tv off) outputs with speakers disconnected. any major inequality in (ohm) reading obviously will tell you so.

sadly you have poor quality loudspeaker. the only thing u can do is plug in a powered speaker set into the headphone socket.

Yes, loose connectiosn, internal integrated amp device burned, bad ground or speakers go to bad.

This could be an earth lead to the cartridge problem, or the cartridge itself. Check the connections.

if all channels poor quality TV problem
if just one or tow channels bad quality not tv problem....

Turntables do not produce "line level" audio which is what is required for input into the AUX on the receiver. If you do not have a phono input on the receiver, you must purchase a phono pre-amp. These are readily available for about $20. This will boost the output of the turntable to line level so you can use the AUX input on your receiver. That will resolve the problem.

that's typical for this mp3 player - probably sounds tinny - nothing you can do about it
