Display Screen Issue-Sunny Treadmill T7515

This week the display screen on my treadmill started fading out about 15 mins into my walk.

I took the cover off as directed on the Sunny website and checked to make certain everything was connected. Everything appeared to be fine. I saw no bent or broken wires. I’ve unplugged the treadmill and plugged it back in several times. I can not find a reset button.

Each time I turn it off and back on the screen appears perfectly but then fades out again.

Please help me solve this issue.


  • it sounds like you made sure all wires are securely plugged in inside

    please not check to make sure there is no crimping in the wires

    It could be that the lower board is not sending voltage to the console and the only way to know this is if you have a voltmeter and can test the red wire & the black wire.

    You should have anywhere from 8vdc to 12vdc on those two wires.
    If you have that voltage then the console is bad.

    If you do not have the voltage then the motor controller is bad.
    (You need to check for volts DC on the black and red wires for the 8-12V.

    if this does not help you can check the magnet/sensor with this link
