Member. If it was properly fused, there may be no damage. If it was not properly fused, it may have blown the reverse protection diode (if it had one), the PS FETs and the power supply driver IC. If there were op-amps on the primary side (used in the protection circuits), they may have failed also.Member. If it was properly fused, there may be no damage.

What damage can reverse polarity cause?
Reversed polarity can damage or short-circuit your electronics, including TVs, radios, phones, and computers. Electronic equipment controls voltage in one direction; thus, the internal components can overheat or short-circuit when you reverse the electrical flow.
What happens if you reverse the polarity on speakers?
If both speakers are wired the same, whether in the correct polarity or reversed polarity, there will be virtually no effect.
Can reverse polarity damage electronics?
This can damage the battery and other electrical components. Any battery-powered product you use while it's plugged in will be energized through its full circuit and thus a potential source of electrical shock. Reverse polarity can cause PCB damage and even PCB failure, yet the damage can be hard to see.
What happens if you mix up positive and negative speaker wires?
Reverse polarity leads to phase cancellation when more than one speaker is being used. Sonically, this causes certain frequencies to be canceled out and has an undesirable effect on the audio quality. Wiring speakers backward won't cause any damage to the devices, nor is it a dangerous practice.
How do I fix reverse polarity?
Reverse polarity is when the hot and neutral wires are wired in reverse. This can create situations where people get electrocuted by using appliances like a toaster or a lamp. Reverse polarity can easily be fixed by switching the wires to their corresponding sides.

Will a speaker work if wired backwards?
This action is known as making the speaker "out of phase," and results in audio oddities. Although this is not dangerous to a speaker or amplifier, proper power delivery and speaker response is not possible with reversed speaker wires.
