Precor error 12

Precor Error 12, Watchdog (Lower PCA) Probable Cause 1. A failure in the lower PCA overloads the low voltage power supply and causes it to drop below the preset level.
2. A fault in the interconnect cable (upper PCA to lower PCA) causing the low voltage power supply of the lower PCA to be too low.
3. A failure in the upper PCA that overloads the lower PCA low voltage power supply causing it to be too low.
Corrective Action
  1. If the error message is continually displayed when the unit is powered up, the upper PCA needs replaced.
    External causes may make the error appear intermittently.
    1. If the AC input of the unit dips significantly during power up test sequences, the test could fail causing the error to appear.
    2. A treadmill connected to a non-dedicated AC circuit can experience this error intermittently.
  2. Determine if the interconnect cable is the cause by substituting a know good cable in place of the current cable. For test purposes, the substitute cable needs to be connected directly between the upper and lower PCA's, without routing the cable internally.
  3. Determine if the upper PCA is the cause by substituting a know good upper PCA for the existing upper PCA.

If you cannot find available power supply to your lcd suggest that you convert a generic WEIYA brand power supply as substitute to your power supply.

Can i substitute a cd 12v 0.1A for a cd 9v 2

No, the voltage and amperage must match for the electronics to work correctly. Using teh wrong power supply is dangerous and could both damage the frame and be a fire hazzard in your home.

PC WON'T POWER UP

With nothing attached to the mother board except 1 stick of RAM in the first slot the power supply and monitor attached, and then  it still turns off ; I would make sure the heat sink was clean Reseat the Cpu and try it again. Now if the same results. I would attempt to substitute a different known good power supply. If that would not work, you are down to substituting a different CPU .

You might try substituting a new fuse. Be sure the replacement has the same rating. You may have a short in your power supply and depending on the type of supply the supply may not start up if it has overload protection. Stargazer
