disconnect speakers and do a master reset.
connect and if it comes back probably one of the speakers..test one by one.

I have disconnected all wires from the back of player, and it still turns off and says "s-protection". If I unplug it and plug it back in, it will work for about 30 seconds then goes off. Would that mean there is a short inside the unit itself?

Contact your Voice Mail service provider. Its network dependent and cant be reset with the handset.

5. Press MODE button to reach the MILE MODE.

6. In MILE MODE, press the SET button. The display will show previous stride input in Inches or CM and start to flash. You will now have five seconds to start changing your stride length. If you do not adjust your stride length during these

5 seconds, you will have to start step 3 over again.

7. To change your stride length while the display is flashing, press the RESET button. Each press of the RESET button will increase the input by either 1 inch or 2 cm depending on which mode you are in. If you hold the RESET button, the numbers will

increase continuously. Release when the display shows the Stride Length for you.
8. Once you have entered your stride length properly, wait 5 seconds - the display will flash and reset the memory - and the display will return to MILE MODE.

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

• Video cable.
• Video adapter on PC (sometimes integrated on motherboard)
• Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual
