Hi everyone... I have a Fender Passport Venue PA system, and it has been acting very strangely. It works perfectly when it's working, but then occasionally just "shorts out" or something, and just creates the loudest most shocking sound I've ever heard. Sometimes the "Protect" red light comes off and on, but that doesn't seem to 100% correlate with the sound issue. It can work just fine for a while, and then BRRRRRRRRRR. And it'll do it even if there's no inputs plugged in. And the "Protect" light sometimes comes on even if no speakers are plugged in.
Any ideas? Transistor? I'm not an electronics guy so I'm trying to gauge whether it's worth taking it in for repair, or if I should just sell it for parts. And I have no clue what these kind of repairs might run for. I called Guitar Center, they said all the local places around me are seriously backed up, so might be a lost cause anyways. But I still want to hear what folks think.
Thanks!

Repair shops around here charge about 80% of the price of a new system, whatever is wrong. Extra for parts if a full set of output transistors is shorted, etc. Then they repair them with used parts like electrolytic capacitors soldered in parallel with the old blown up one. Mr Bee whose sticker was on that TV (found on the curb for the garbage) is no longer in business. If the shop spends as much time as 80% of new one costs them, they give it back to you as unrepairable. You have to pay the "estimate charge" to get it back. Else they keep it for parts.
Sounds like a loose solder joint or connector to me. A time consuming problem to find. I bought a 1300 w amp for $55 with a printed label "DO NOT USE CHANNEL A" and 3 sets of initials inside. That's 3 techs who didn't find the bad solder joint in channel A.
Best advice is talk to a competitor DJ as to who he uses. Or more likely to get a straight answer, a bar band. If you buy the sound desk guy a round he may feel friendly to you and tell you some truth.

Sounds like bad connection/ intermittent connection.
Could be any , would be a guess without inspection.
Guess would be neutric speaker jacks damaged from twist lock / genric cable.
Or any large component on the board from shocks /movement / vibration has loosened.
or inputs / outputs or effect loop jacks if it has them

Loose ground connection seems likely leading to mains hum at high volume. Connectors mounted on PCBs are a common failure point due to mechanical flexing, but a PA system gets a rough life and mounting screws can eventually work lose over time, or PCBs develop hairline cracks.
Finding it is just a matter of patience. Better just to get it out every now and again, and methodically inspect everything. And not all at once, that’s how things are missed.
It could be a +48v phantom power intermittent connection DC discharge, which can sound like a shotgun.Hi everyone... I have a Fender Passport Venue PA system, and it has been acting very strangely.

If it is, turning the front panel phantom power switch off might cure the problem. If the switch was not on, oh well..
If you don't use any mics or DI's that use phantom power, and it is turned on, the discharge is more likely.
