That means you have a bad speaker, speaker wire, or a componet in the output stage of the amp blew out. First thing to try is to disconnect all the speaker, Turn on the unit. If it still reads the same, you have a problem with the amp. these are solid state units and have no user replacable parts inside of them.. You will need to have it serviced or get a new unit, as to have these repaired or even estimated these days is very costly. Good Luck Please dont forget to rate this thread.

SOURCE: I have an error on the display screen which say's

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

Introduction

The DVD Upgrade is an advanced modification to your DVD player, which adds extra features and enables you to get more from your machine. The upgrade supplements the DVD player and in no way harms the playback quality or removes any performance features of the machine.

The following DVD players are supported by this version of the DVD Upgrade:

 Sony DAV-C700
 Sony DAV-S400
 Sony DAV-S500
 Sony DAV-S800
 Sony CMT-S9D

Macrovision & CGMS disable

All DVD players have a system called Macrovision built in to the player, which is designed to stop the copying of DVD discs to video. However, this system can have adverse affects on some projectors. For this reason the DVD MOD Upgrade disables Macrovision to solve any problems.

Protect


The protect message indicates that a problem was found in the output stage of the amplifier. Unless this gets repaired, nothing will work. As a verification that the speakers or the wires are not the problem, unplug all of the speakers and try again. If protect still is displayed, the problem is inside the unit.
