I am highly skeptical that the CPU is the problem; protection mode is designed for protection of the amplifiers.

Use an artists brush to remove any dust and grime off the voltage rails and heat sinks. Reinstall the CPU and the chassis cover. Turn your attention to the rear connector panel; check for any broken or loose speaker terminals. If your speaker wires are still connected look for any stray wire strands and pull them off or bend them away from the connector panel. Check the connection for tightness, or simply disconnect any corroded wiring that you may not be using a banana or spade connector with and clip and redress it. Perform the same inspecting and maintaining procedures on all of your speaker channels.

When placing the receiver it must also have adequate air flow around it. Anything you can imagine that would allow the unit to retain heat increases the chance of it getting it into protect mode for thermal protection. Out in open air is best.
When the receiver is properly positioned and all connections are secure, power it up; it will likely still be in protect mode. If so, press and hold the power button down until the unit "clicks" inside the chassis; this takes approximately 15 seconds. Protection circuit is reset and you can now operate the receiver.

Unit goes into protection after a few seconds. Yamaha amp model no RXV 350


Disconnect all the speaker connections, and just switch the set ON. Even now the set goes to protection mode, the fault will be with its audio output section circuit. If it does not go to protection mode without speaker connections, check all the speakers. Connect on by one at a time; and switch ON the set; thus you can get the faulty speaker box. http://electronicshelponline.blogspot.com/

If the receiver goes into protect mode with no speakers connected, you will have to troubleshoot the receiver itself to find and correct the problem.

A-SV640 KEEP GOING TO PROTECT MODE


Hi, try powering up the unit with out any speaker connected if it still goes to PROTECT try factory reset if possible.
To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter standby mode.
If this does not fix your problem you should take your unit to service . :)

Acer pc and lg monitor blank screen says power save mode on start up, anyone know how to fix this?


Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU.
It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.

Amp goes to protection mode. if the fuse is too small?


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. . Double check all connections. Good luck.
A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

My denon avr1200 receiver once it is turned on goes into Protection mode. How do you reset or make work?


The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.
