Protection displayed on screen

The word "protection" is displayed on the screen after a 1 second warm-up. The fan is working during this first second. Then nothing works but the screen display.

My 07 Saturn Relay shows ac off for engine protection but the gauge shows cold. The hoses feel normal. What is happening?

A/C Off For Engine Protection
Refer to Cooling System Description and Operation

DTC P1258: Engine Coolant Overtemperature - Protection Mode Active.
This is something you need to take to a qualified repair shop .
The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) or engine control module (ECM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood junction block. The ground path is provided at G100.
During low speed operation, the PCM/ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the cooling fan 1 relay coil, closes the relay contacts, and supplies battery positive voltage from the cool fan 1 maxifuse® through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan relay and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation, the PCM/ECM supplies the ground path for the cooling fan 1 relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM/ECM supplies a ground path for the cooling fan 2 relay and the cooling fan relay through the high speed cooling fan relay control circuit. This energizes the cooling fan relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the cooling fan 2 relay coil is energized closing the relay contacts and provides battery positive voltage from the cool fan 2 maxifuse® on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.

CPU Overheated
If the system shutdown automatically after power on system for seconds, that means the CPU protection function has been activated. When the CPU is over heated, the motherboard will shutdown automatically to avoid a damage of the CPU, and the system may not power on again.

In this case, please double check:
1. The CPU cooler surface is placed evenly with the CPU surface.
2. CPU fan is rotated normally.
3. CPU fan speed is fulfilling with the CPU speed.

After confirmed, please follow steps below to relief the CPU protection function.
1. Remove the power cord from power supply for seconds.
2. Wait for seconds.
3. Plug in the power cord and boot up the system.

Or you can:
1. Clear the CMOS data.
2. Wait for seconds.
3. Power on the system again.

If after clearing the CMOS you still have no display, you may have damaged your motherboard, CPU, or RAM. If you need further assistance with this Motherboard, let me know.

Where is the fuse inside the power supply model fsp200

The unit is only 200watt and the fuse cost about $2,Thats if there one built into it,
The replacement power supply is about $20-00 NZD
Probably 20minutes to fix (for a novice) depending on their skill level and tools available,

BEST ADVICE Replace it

Power is something you dont want to mess with because it can kill.
The power packs are replaceable but people arent.
Be very careful and dont mess with the power.

I am an Electrician and I respect power.Misterdj

Hi,

Take every single cable out of the unit, now power on the unit.

If the power protection still shows then there is an internal fault, usually a short or a component defect.

If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.

Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.

Cheers

Protection displayed and shuts off

The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.
