A little interference to the FM radio

First off, not talking about the modern FM stations.
I had located three classic station, but, there are hard to find stations. I can hear the music playing but it's weak too much static interfering. Also, i found out since i listing to music in my sleep, when turning off the TV, it seems to comes in great, but next day when turning on the TV, the radio station fade out, just static.

    Your TV is generating huge amounts of "RFI" (radio frequency interference), probably due to the microprocessor and other digital electronics in it. The "hash" may be inducing noise either at the antenna (i.e., at the :"carrier frequency" of the FM radio station) or in the "intermediate frequency" section of the radio. The radio has a local oscillator & mixer to create a lower-frequency signal for the radio to work with. In the case of FM, that frequency is 10.7 MHz, much lower than the broadcast signal frequency. All of the tuned circuits are subject to induced noise from RFI.

    Moving the radio and/or antenna may mitigate the problem. It may not take much -- just a couple of feet, or turn the radio or the antenna 90 degrees relative to its current orientation.

    You might also want to try plugging the radio into a different AC circuit (i.e., one that's on a different breaker) to see if that helps.

    I'd at times watch sports, and tune into a sport radio station because I did not like the rambling od certain commentators and excessive commercials

    And other times I would listen to music while a sport was on...
