I know nothing about stereos. My Marantz SR5000 went into a mode where it just says "protect." I tried to reset it with the reset button, but it does not work. Is there something simple I should do? Is there a fuse that needs to be replaced, or do I need to send it to the factory?

Re: Marantz SR5000 Protect mode
The Marantz SR5000 and others of it's make, design type, and year group are prone to this problem. Many such units can be reset by pressing a sequence of three buttons with sporadic results... the SR5000; however, does not provide any such option. If the "Auto protect" mode comes "on" then you know it's not a simple power supply "fuse" problem that can be fixed for a dollar by opening the case and replacing the glass fuse with one of the same rating value that is stenciled on to the power supply circuit board. (Easier than trying to read the old fuse.) If you can get the schematics and know a bit about replacing electronics parts using a low-power soldering iron, then you might want to take a shot at fixing it; otherwise, it's time for recycling. (Tip: Look for discolouration on a part on a circuit board first, this indicates overheating and a possible short. Then trace the schematic circuit for the "Auto Protect" circuit to diagnose which integrated circuits is at fault.) Typically, it costs more to fix it in a commercial shop than it's worth as someone has to pay the cost of benchtime diagnostics... the repair part is fast once the faulty parts are discovered. There are free sources on-line of the service guide for this receiver; however, downloading the plethora of rar files to assemble a complete manual is a challenge.

------------------ " display mode OFF"
You can select the display mode for the front display of the SR7001.To select this mode, press the DISPLAYon the remote control or the front panel.When this button is pressed, the display mode is switched in the following sequence.Input Mode?Surround Mode?Auto display OFF?Display OFF?Normal Mode?Input ModeNormal Mode:Displays the selected input function. If the function has been renamed using the Function Rename feature (see page 26), the renamed name appears on the display.Input Mode:Displays the input mode set via the Function Input Setup feature (see page 25).Surround Mode:Displays the status of the selected surround mode.Auto Display Off mode:The display is off. But, if you make a change to the unit such as the input or surround mode, the display will show that change, then go back to off after about 3 seconds. When changing the volume, it is not displayed.Display Off mode:The display is off completely.Note: • Only the DISP indicator will be illuminated on thefront display in display off condition http://www.scribd.com/doc/53431794/Marantz-SR-8001-Owners-Manual
Your stereo went into protect mode to prevent complete failure of the amplifier inside that radio. Most of the time this happens from playing the stereo real loud for a real long time and it overheats. Most of the time disconnecting the receiver/stereo and letting it cool all the way down or at least 5 minutes and then reconnecting it to the power source will reset the protection mode. You want to make sure you are keeping the radio cool. Don't stack anything on top of it and try keeping a small fan blowing on it to expedite the heat out from the unit. Also turning it down every now and then to let everything cool down a bit will help prevent it from going into protection mode as well.
Try disconnecting your battery, reconnecting it, and resetting your stereo. If that doesn't work, the constant power (yellow wire) or ignition wire (red wire) may have come in contact with ground or isn't properly connected. Make sure everything is connected properly and try resetting your stereo. If it is still flashing "protect", the unit needs servicing Contact JVC Customer Care Center at: 800-252-5722.
Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!
Not unless you know how to troubleshoot solid state electronics. If you disconnected the speakers and the unit still goes into the protect mode, most likely you have a short in one of the power output stages. Good Luck
