Fender PD-250 Shutting down

I have a Fender PD-250 which works great for about 3 to 4 songs then just shuts down all by itself. It's about 10 years old, I think it may be overheating. Are there any tricks to fix this easily or do i have to take it in?

    I have a Fender PD-250 which doesn't work properly. When I plug in an audio input, it doesn't amplify the sound. In fact when I turn the volume knob up, the volume lowers and vice versa. I'm thinking it had a short. Is this fixable or do I need to send it it to an authorized repair centre?

I have fender passport pd-250 the protect light on and the power light geos off

One or more of the power transistors are shorted. There are eight transistors in the amplifier section - 2 high & 2 low for each channel. This unit is difficult to open up to work on.

Unplug unit and check speakers with a multimeter to make sure they are not shorted.
Take off front panel (8 screws).
Remove power supply shield with yellow tape (2 screws).
Remove 2 screws holding top of power supply, loosen bottom screws.
Replace front and hold in place with a couple screws.
Turn unit around.
Remove screws holding heatsink (6 screws)
Open rear storage door.
Carefully pull amp section out, being careful of tightly routed wires. Note any connectors you disconnect.
The amplifier is the board on the top, the power supply is in the silver box.
Push the power supply forward and loose the black screws holding the amplifier board bracket closest to the heatsink.
Loosen the top brass screws holding bracket to heatsink and remove the bottom screws.
Remove all eight of the screws holding the transistor brackets & transistors to the heatsink. Look and take careful note of how the plastic insulators weave through the transistors. If you get this wrong, you can short out the whole amplifier when you turn it on.
Slide the amplifier board down and out where you can get to the bottom. Note the wires and connectors going to the small protect board over the amplifier.
Check the transistors with a multimeter to find the shorted ones. Remove and replace bad transistors. These are connected in pairs.
Reassemble in reverse. Be careful of reconnecting wires and insulators. Don't test until the amplifier PCB is back in place and you're sure of all wires. If the PCB is touching the power supply, you'll short it out.

Good luck, I told you this wouldn't be easy!

When the the Fender Passport 250 is plugged into the computer through the stereo out, there is feedback/buzz in addition to the sounds the microphones pick up, even when the mikes are off.

If there is a 120hz buzz then there is a ground loop between the computer and the passport. You need to get a ground isolator to go between the two. If the buzz is deeper the may be a audio ground off or the hum is comming from the power supply

Left speaker channel dont work , sound shorted

Make sure the PAN controls are set to center. If they are, the amp may have a failure. Hint: these systems are hard to work on due to the way they are assembled.

How do I open a fender passport 150 speaker cabinet?

There are screws running down the sides of the front panel which you will have to remove. The circuit board is secured to the front panel by the nuts, washers etc. that the controls and jacks are fastened with. Once you get the panel; loose gently move it forward so you can see any connections to the circuit board. Make careful note of all of these and draw diagrams. You will have to completely remove the panel from the enclosure and then the circuit board from the panel. The jack in question will be mounted on the circuit board and soldered to it on the reverse side. You will need to unsolder it, obtain an exact replacement, solder in the replacement and replace the board on the panel and the panel back in the enclosure. Make sure everything is connected exactly the way it was originally. Hope this helps.

Fender Passport makes loud chirpping knocking sound after on for only 5 10 minutes

I have one that is doing the exact same thing. It's at a Fender
Authorized Service Center now. Hopefully dude can find the
problem. Fender says there is a 5 year warranty on it, so I
expect them to make good on their promise. Did you get
yours fixed?
