My stereo keeps turning off when I listen to a station 101.5 in New Jersey


The only thing that can be is that you have set a timer "sleep" function for that station. I have looked at the manual and it states you can programme a sleep setting for a radio station.
The instructions are on page 12. But I have extracted them below:

1 Press the ON/STAND-BY button to turn the power on.

2 Press and hold the CLOCK/TIMER button.

3 Within 10 seconds, press the or button

to select "ONCE" or "DAILY", and press the MEMORY

button. Set the clock to the correct time if "ONCE" or

"DAILY" does not appear.

4 Within 10 seconds, press the or button to select

"ONCE SET" or "DAILY SET", and press the MEMORY

button.

5 To adjust the hour, press the or button and then

press the MEMORY button.

6 To adjust the minutes, press the or button and

then press the MEMORY button.

7 Set the time to fi nish as in steps 5 and 6 above.

8 To select the timer playback source (CD, TUNER, USB,

iPhone/iPod, TAPE or AUDIO IN), press the or

button. Press the MEMORY button.

When you select the tuner, select a station by pressing

the or button, and then press the MEMORY

button. If a station has not been programmed, "NO

PRESET" will be displayed and timer setting will be

canceled.

9 Adjust the volume using the VOLUME control, and then

press the MEMORY button. Do not turn the volume up

too high.

10 Press the ON/STAND-BY button to enter the power

stand-by mode. The "TIMER" indicator lights up and

the unit is ready for timer playback.


11 When the preset time is reached, playback will start.





The volume will increase gradually until it reaches the

preset volume. The "?" or "DAILY" indicator will blink

during timer playback.

12 When the timer end time is reached, the system will

enter the power stand-by mode automatically.

Once timer:

The timer will be canceled.

Daily timer:

The timer operates at the same time every day. It

will continue until the daily timer setting is canceled.
Cancel the daily timer when it is not in use.

Usually when a TV starts producing sound but no picture a couple of faults can be attributed to it.
Least among these causes is the contrast or brightness. If either of them has been set to the lowest then you would get volume but no sound and if the channel has been changed to another station with no station then the blinking is bound to happen.
In another scenario if the picture IC in the unit has blown then you have to refer the unit to an expert to fix it. But be rest assured that the blinking lights are as a result of the TV being on a station with no reception.
Hope this solution has been helpful?
