Loud pop, then turns off

Usually loud pop signal blown capacitor

The flasher itself is toast. It’s mounted in the in cab fuse box. Looks like a small cylinder, usually silver metal or black plastic. Pop over to a parts store, usually about 5 bucks.

loud pop can be a bad fault on the power board. would think it would be the upscale side of the power board. big 3 pin voltage controller. it will also blow in front of it. you will be able to test it with a meter.

starter shorted causing the battery to oveheat and burning the positive battery cable

The Main Tuner signal board is dead.Replaced this board will solved this.Tries Shopjimmy.com,Ebay.com to buy a refurbish Tuner signal board for the replacement.

The "pop" that you hear when turning off the system is caused be the amp not shutting down clean. This can be caused by several things -like a poorly designed or built amp. It can be caused by a poor chassis ground cable, poor line voltage coming into the amp, or a malfunctioning amp (if it didn't used to do this before). It may also be caused by the line-out signal coming from the head unit. If the head unit has a problem with the pre-amp section and sends the "pop" signal to the amp, the amp will just do what it's told to.

I would recommend starting with making sure that you have a solid power and ground connection from the battery and to the chassis. Next, I would try turning down the amp's gain if it's set too high and see if that helps.

What's feeding it? The sub comes on automatically when it senses a signal, which seems to be what it's doing. Perhaps the loud clicking is originating at the other end of the cable.

Hello SuziCanevaro,

This may have been the sound of electrolytic capacitors exploding. I would not suggest plugging the set back in until you can have it checked by a qualified TV technician. If you are skilled in Electronics and would like to work on this yourself, you will need:

The schematic diagram, a multimeter, a signal generator, an oscilloscope, and an isolation transformer.

I hope this helps,

Thank you,

If this is a heat pump system it is possible that your fan blade is hitting ice on your condenser coil.
