Check there is controller inside on which there is DZ1 and DZ4 diodes which usually get damaged/burned out. I dont know values of the diodes but replacing them would solve the purpose.

If i turning on music player and starting the song the player just turning off. i cant lisen to music anymore.


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Proform gr 80 recumbent exercise bike cant get the display to turn off when I get off bike. battery powered?


The GR80 uses for type D batteries. The battery compartment is on the bottom of the console, look for the D-shaped battery door, press the tab located towards the front side of the console and open the door. Careful, the batteries may fall down if you open the door - type Ds are heavy enough to be felt when they fall on your feet.
