I have a Precor C956 which has been working fine but turned it on last night and the display console isn't working. No lights on at all. Have taken the console front off and everything seems to be in place. I'd be very grateful for any help.

This is an error code for 1 of 2 things. Something was spilt on the display causing a detected malfunction. Or, you are experiencing a power sag where the unit is plugged in. Try an isolated AC circuit. (Nothing else is ON or plugged in)

Precor Error 05, Key Depressed at Power Up Probable Cause 1. A key is permanently depressed on the display.
2. An interface chip (IC) has failed in the upper PCA's keypad.
3. Liquid (cleaning solution or sweat) may be on the surface of a touch sensitive display.
Corrective Action

1. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 is eliminated, the keypad is the cause and should be replaced.
2. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 still appears, the upper PCA* is the cause and should be replaced. *Upper PCA's most commonly do not come with software. Remove the software (chip) from the existing upper PCA prior to replacement and install into the new upper PCA.
3. Wipe away all liquid from the touch sensitive display. Reset power to the unit. If the Error 05 is eliminated, the liquid was the cause.

This link will take you to the parts available for these models. Because most machines are serial number specific, you will need to narrow your search based on your particular model and serial number.

The power switch on Precor treads is also a circuit breaker. If it trips when plugged in, you have a dead short in the machine.

please Adjust the Reed SWITHC,test for open or faulty. Clean it, and tight the connector very well.see the diagram
2) tight and clean the RIBBON cable for keypads, very well
3) replace batteries by new ones ,with alkalines

Dear Sir:
You must test the power supply inside of TV, if you have skill for to do oit use DVOM, otherwise you must call some service tech, or go to repair shop.
However try to tight every connector wires, for loose, breake(test the wires for continuity) or burn.
God bless you.

There is an on/off switch that needs to be turned on. There is also a safety key that needs to be attached. If those are both correct and there is still no power then you may have some wiring problems that you should call a professional for.

Precor Error 44, Un-commanded Lift Motion Probable Cause 1. Intermittent or bad connection in the lift position sensor(potentiometer).
2. Lift position sensor (potentiometer) is bad.
3. Lower PCA is bad.
Corrective Action

1. Bad or intermittent connection of the lift position sensor (potentiometer) is the most common cause of the error 44. Inspect all wiring and connections related to the lift position sensor (potentiometer). Repair or replace wiring connections as necessary.
2. Monitor the lift position number displayed while operating the lift in diagnostics mode. If the reading makes large changes or is erratic, the lift position sensor (potentiometer) is likely bad. Replace the lift position sensor (potentiometer) or lift motor if the lift position sensor (potentiometer) is internal to the lift motor.
3. If the lift moves without any command entered either manually or through a program, replace the lower PCA.
