This needs to go to the repair shop. The protect mode is turned on when either the power supply has a problem or one or both power amplifiers have a problem. These are often blown components.

These units are HARD to work on. To open you have to first remove then front panel before you can remove the back panel that has the power supply and power amps/heat sinks.

Compare repairs of these units to working under an automobile dashboard!

Hint: On startup, use a series 150 wat lamp to limit current while repairing. SInce these use a switching supply operating off the input line, use an isolation transformer for personal safety.

Could a bad cable connection make a fuse blow in my fender passport 250, or cuase any problemmwith ouput from my speakers...?


A shorted speaker cable could cause this... however, what you do is to replace the fuse BUT wire a 150 Watt lamp in series with the power input... This acts as a resetable fuse for testing. If the lamp stays lit, you still have a failure.

Protection light came on then went of now i get nothing when i flip the switch to on.


Likely an overload failure caused the protect light to come on, and then the fuse blew so all power is off... Do NOT replace the fuse as you will LIKELY do additional damage to components. Take unit in for repair immediately.
Note: These units are really hard to work on due to the way they are packaged.

The protect light is the only light that comes on


Either one of the amps or the power supply has blown. The protect light means the power supply has been shut down due to overcurrent. Take unit in for repair. These are hard to work on due to packaging.

We have a Fender P-250 PA system. We get the protect light on when we turn on the system rather than the green power light. We can not get it to operate. Please advise... Gary


Likely there is either a failure in one of the power amps or the power supply. The protect means excess current is being sensed.

You need to take in for repair... these are really hard to work on due to the packaging.

Amp goes into protect mode as soon as switch is turned on. Pasport 250


There is a problem with the internal amp itself. These are extremely difficult to access. Contact Fender for a local authorized service center.

Protect light comes on when power on


This indicates either one or more of the amps have a failure OR the power supply is being overloaded which is usually also caused by failure in the amplifier.

Occasionally a power supply failure causes this problem as well.

Due to the way these are packaged, they are a real pain to work on for repairing.

My Fender Passport stays in protect mode.


I have one that has done the same. It is the next smaller size. The power supply fried a toroidal inductor in mine. Frankly, these things are a major pain to work on. You have to usually remove the front panel before you can remove the back power supply and power amp section.

If you have warranty coverage USE IT !!!

The protect feature in mine monitors the power supply load and shuts down the supply if it senses overload. They are hard to work on as you have to bypass the protect to troubleshoot and get to the root cause.

Use the old light bulb in series trick to limit the current.

Fender passport goes in to protect


I had a problem like this that was caused by a short between the two windings of the toroid in the power supply.

The solder blob is probably supposed to be there as there are numerous common ground points.

This unit is miserable to work on....

The 'protect light' comes on Fender PD150 Portable Sound System


The protect circuit is activated by a current sensing transformer in the *input* of the power supply. If any of the subassemblies of the unit (or all of them in combination) draw excess current then the protect light will illuminate and the power supply shut down to prevent any damage to the system.

The circuitry in the power supply is fairly robust as well as fuse protected so it is unlikely that the power supply itself has failed. More than likely one of your output power transistors has been shorted and it is easy to check this yourself if you are interested in doing so.

Furthermore if you follow a few *simple* precautions you can do this safely and confidently.

Post again on this thread if you are interested and I will spew the details.
