SOURCE: my kw-avx840 was showing a

The faulty wire was shorting on the ground. When that happened the current flowing thru the amplifier top which that wire was connected got severely overstressed. This is why the safety system was triggering. By reseting it you were just making the problem a lot worse - you were forcing the amplifier to run with its output shorted. So it was to be expected that it eventually failed - it severely overheated and it got shorted itself internally. Now it's the short in the amplifier the one that is triggering the error message. And because the short is on a critical part you can no longer reset it - the power source itself has shut down.
The radio will have to be dismantled and the failed final amplifier identified and replaced, a job for a pro - time to take it to an electronics repair shop.

Onga pump ppp750 plugged in will not start and no prime noise?

If needed, the owners manual for your pump is in the link below. This is a pump me for countries outside the USA. But if you are getting nothing, it is possible that it is miswired, or you have a failed pump-dead.

but by the wording of your question, it appears that it may have worked at one time, the way it is currently wired? If so, and nothing has changed with wiring, or any of the installation, then it is possible that if you hear nothing, either power has stopped going to it, or the pump motor died.

Check your breaker, any fuses, or wiring to the pump
and remember this one very important fact, to reset a toggle style breaker, you need to push it ALL The way to the off position, sometimes it is harder than you think, and then you can turn it to the on position. This resets a tripped breaker.

I have a holden vt commodore, I installed the Alpine CDE-152E Head Unit and now my speakers don't work. Sound was fine before I took the stock stereo out.

Well looks like you have miswired, miscongigured or its a faulty unit. I believe you should check all your wiring, and make sure the install is as per the manual. Disconnect your speakers and check them for continuity with a meter. They will be ok Theres something you haven't done like connecting the pre-amp to the main amp or the plugs are miswired

Unit warning check wairing than reset

It is caused by miswiring or shorted speaker line. You need to take it to service if it already happened three times. If you are a tech, reply back for possible reset procedure. No guarantee though.

Installing JVC KD-R740BT in 1997 Ford truck, keep getting "miswiring, check wires and reset" message

Check speaker wires. All four speakers must be independent. Means no shorting to chassis.

My surrounds are not working right

This will sound stupid but I've made this mistake before (and I usually know what I'm doing...) so here goes.

Read the manual (check HK's website) - specifically the page where it has the diagram describing how to hook up all the speakers. I'd bet you miswired them due to some confusing labeling on the back.

Alpine 7800F No sound, don't read.

Blown audio output IC, possibly from miswiring speakers, or accidentaly shorting out one of the speaker wires. It will need to be repaired, or replaced.
